Removing the engine sump on a VAZ 2107 and replacing the gasket

How to remove the pallet on Niva 21213

Lada 4x4 (VAZ-21214): Replacing the oil pan gasket

We replace the gasket when an oil leak is detected at the junction of the crankcase pan and the cylinder block, when tightening the pan mounting bolts cannot eliminate the leak.

We carry out the work on an inspection ditch or overpass.

We remove the mudguards of the engine compartment (see “Removing the mudguards of the engine compartment,” p. 282). Drain the oil from the engine (see “Changing the engine oil and oil filter”, page 18). We unscrew the nuts securing the cushions of the left and right power unit supports to the front suspension cross member brackets (see “Replacing the power unit supports,” p. 97). We unscrew the nuts and bolt securing the front axle gearbox to the suspension brackets of the power unit and the engine cylinder block (see “Removing the front axle gearbox,” p. 191).

Place the adjustable stop under the clutch housing.

. raise the power unit. For fixing the power unit.

. We insert wooden blocks between the support pads and suspension brackets.

. and lower the adjustable stop.

After cleaning the mating surfaces of the cylinder block and oil pan, install a new gasket. We carry out assembly in reverse order.

Removing the engine sump gasket on a VAZ 2121 and Niva 2131 is done to replace it in case of damage, which is accompanied by the presence of oil smudges at the junction of the sump and the engine block. The cause of a leak can be not only its damage, but also deformation of the pan itself, which often occurs as a result of engine overheating. In this article, we will consider the process of replacing the gasket. First of all, you need to try to tighten all the bolts securing the pallet, while observing the cross-to-cross sequence; if this step does not help, then proceed to the repair. First of all, prepare a standard set of tools; the car must be driven into an inspection hole or overpass. Then do the following sequence of actions:

• First of all, you need to drain the oil from the crankcase. It must first be warmed up; to do this, the engine must run for several minutes. Hot oil drains better.
• Next, we dismantle the protection of the oil pan and the engine compartment.
• Loosen the left and right power unit mounts.
• We disconnect the gearbox mount to the brackets of the front axle and the engine block, which will give us the opportunity to slightly raise the power unit and thereby remove the pan.

We place an adjustable stop under the engine, lift it, which allows us to make the previously loosened support fastenings, and insert suitable sized wooden blocks into the gaps between the supports and suspension brackets. Then we lower the adjustable stop, thereby putting the load on the wooden blocks.

• Using a ten-point socket, unscrew all the bolts securing the pan and remove it.
• Next, remove the gasket itself.
• Before installing a new one, thoroughly clean the mating surfaces on the block and pan.

At this point, the repair work to replace the oil pan gasket on the VAZ 2121 and Niva 2131 has been completed. We install the new one in the reverse order.

Remove the pan in the field without removing the engine

How to remove the oil pan on a foreign car

Instructions are provided for the 2003 Mitsubishi Space Star 1.6. In this case, the pan is bolted and located above the muffler. First you need to drain the oil and unscrew the bolts securing the exhaust pipe to the muffler.

Now place a stop under the muffler and remove the rubber bands (usually there are two of them). The stop is necessary to ensure that the lambda probe is not overly stretched and the wires are not damaged.

First you will have to unscrew the gearbox casing, which prevents you from removing the necessary part - you need to remove the casing itself and the plate under it.

Cover that needs to be removed

Next, unscrew the bolts located around the perimeter of the pallet (with a 10-point head), due to which it is held in place.

After this, the tank is still held in place by the sealant. In order for the pan to begin to detach, it is necessary to tap its body with a rubber mallet. If the spare part is not yet worn out, do not hit it too hard, otherwise you may pierce the metal.

Now the part will come off easily

After removal, it is important to check the condition of the oil sump mesh. If there are deposits, the mesh is unscrewed and washed in solvent

It is also important to remove any remaining sealant and then treat the surfaces with a degreaser.

Old and new oil pans

Then everything is put together in reverse order.

In addition to the instructions given, you can also watch a video with step-by-step removal of the pallet:

Diagram of the standard crankcase ventilation system

The crankcase ventilation system of VAZ engines consists of two circuits that operate at different load modes and speeds:

• The small ventilation circuit is connected to the valve cover and the intake manifold (behind the throttle body). This connection diagram provides intensive crankcase ventilation due to the vacuum that occurs in the intake manifold when the throttle is closed. To avoid an effect such as hyperventilation, the cross-section of the small circuit is limited by a jet in the cable throttle body with a diameter of 1.7 millimeters. This circuit operates in the region of 800-1500 rpm.
• A large ventilation circuit is connected to the valve cover and the air pipe (in the pre-throttle space). This scheme provides intensive crankcase ventilation at high speeds. The cross section of the large contour is 16-18 millimeters

Why are oil seals needed and how are they designed?

Engine cylinders need protection from foreign substances entering the combustion chamber. It is the oil seals (or valve stem seals) that play the role of a kind of protector. Their task is to prevent oil from penetrating while the valve stems are operating. If the caps have lost their function, they must be replaced. Otherwise, carbon deposits will begin to appear on the walls of the engine, which will lead to increased oil consumption.

Valve seals have a very simple structure. They consist of only three elements:

1. Base. This is the oil seal frame, which is made in the form of a steel bushing. This element ensures the strength of the spare part.
2. Spring. It ensures the tightness of the mechanism by pressing the rubber tightly against the valve stem.
3. Cap. This is the main element of the device, made of rubber. With its help, excess oil on the rod is eliminated.

Elimination of internal leaks.

If the cause of large internal leaks (fumes) is the hardening of the oil seals, we also recommend that you first try a simple and inexpensive method - the German Liqui Moly Oil Verlust Stop additive.

An important point in preventing oil leaks is the use of anti-friction additives, which reduce friction and prevent engine wear. Anti-friction additives in the engine extend its life by reducing ring wear, which will reduce engine oil consumption. You can read more about the differences in antifriction additives here.

An integral part of wear prevention is the use of the correct and recommended lubricants for this type of equipment and regular flushing of the engine before replacing lubricants, observing the recommended replacement intervals. You can select the necessary flushing here.

In addition, it must be remembered that improper operation of the fuel system contributes to accelerated waste consumption. For example, if the injectors are dirty, then they incorrectly spray fuel into the combustion chamber, which directly correlates with the amount of oil consumption (waste).

In this case, the fuel system should be cleaned, for which there is also an inexpensive and simple solution - fuel additives (in the tank). You should choose additives from well-known, reputable brands that will not only clean the fuel system, but will also do it safely for all fuel equipment. We recommend choosing fuel additives from the German company Liqui Moly. More detailed information can be read here.

RESULT

Each engine has a clearly established lubricant consumption rate. There is a normalized level of consumption and oil consumption is higher than normal. The level of consumption that does not meet established standards occurs due to two factors: external leaks and internal ones (waste). If your oil consumption is low and has only recently appeared, there are simple and inexpensive ways to fix the problem. To do this, first of all, use oil system sealant. Flushing the oil system, anti-friction additives and fuel additives will help you prevent consumption that does not meet the standards. If the consumption is higher than optimal, then this may result in other reasons for increased oil consumption, which, in turn, will lead to large expenses for engine repairs.

Replacing the oil pan gasket on a VAZ 2110 with your own hands

Actually, why is this crankcase gasket necessary? The “tens” engine includes many units, components and systems. The crankcase is the engine body and plays a vital role. After all, it is it that contains all the main elements of the engine inside itself and provides them with the necessary protection and allows oil to circulate.

Main reasons for replacement

In fact, replacing the oil pan gasket on a VAZ 2110 may be necessary if it is damaged. There are not many reasons:

• Impacts on the oil pan;
• Gasket deformation;
• Exposure to high internal pressure, which violates the integrity of the gasket;
• A confluence of several factors at once.

Symptoms of a problem

If the replacement is carried out incorrectly, the rupture may occur again, foreign particles will get inside the crankcase, sealing will be insufficient, which will lead to failure of the engine or its individual components.

It would seem like a simple gasket, but what a burden of responsibility lies on it.

To determine the need to replace the gasket, you should pay attention to the characteristic signs of such a problem:

1. Oil is leaking.
2. There is a decrease in pressure in the oil system.
3. The oil level drops more rapidly than usual.

Preparing for work

Preparation plays a big role in successfully replacing the oil pan gasket. Actually, this event will not be very difficult.

• Drive the car into the pit or lift it using a lift;
• Provide high-quality light so that you can carefully inspect the condition of the pallet;
• Remove the crankcase protection if you previously installed it on your VAZ 2110;
• The oil pan must be cleaned because a large amount of dirt and oil accumulates on it. It is also recommended to clean the areas adjacent to the oil pan;
• The easiest way to detect a leak is when the engine is warm, but only at idle speed. This will increase the pressure in the oil system and will show how serious the problem is with oil leaking through the oil pan gasket.

Replacing the pan gasket

Nowadays, various types of sealants and additives that can eliminate leaks have become quite popular. But these are all the machinations of marketing companies. In fact, these funds are of little use. The sealant can only give a temporary result so that you have time to get to the garage or service station, where you can change the gasket.

Attempts to use such methods sometimes end sadly. The pressure increases, the gap becomes even larger, and the oil leaks out almost completely. If such a problem catches you on the road, far from the service station, no one will envy you.

Now we will tell you exactly how this is done.

1. It is necessary to remove the oil pan in case of a leak or during engine repairs. If you need to repair the engine, but you have never installed a gasket before, we advise you to combine these two activities.
2. Also, dismantling the crankcase and installing a new gasket makes it possible to perform another useful procedure for your car - changing the oil. Combine them.
3. First of all, remove the mud flaps from the front wheels of the car.
4. Now drain the oil. If you have changed it at least once, there should be no problems at this stage.
5. Unscrew the three bolts that secure the lower clutch housing cover and remove it.
6. Arm yourself with a 10mm socket, with which you unscrew all 16 bolts responsible for fastening the oil pan.
7. Remove the pan. It would be advisable to clean it, rinse it thoroughly with special products.
8. After removing the pan, you will find a gasket at the joints. If the car has been in use for a long time, its condition will not be the best. But you don't care anymore, since you plan to change it.
9. Remove the old gasket from the joint and clean the surface of all kinds of contaminants. The cleaner the connection, the more securely the new gasket will fit into its rightful place.
10. It is recommended to strengthen all joints using a special automotive sealant. The gasket itself does the job well, but it is never a bad idea to supplement its level of protection. Sealant is an affordable pleasure for every car owner.

As you can see, the procedure for replacing the oil pan gasket in a domestic VAZ 2110 car is not at all complicated. Try to combine several procedures at once, since you decide to remove the pan. Let’s hope that you won’t have to repair the engine; the “ten” will serve faithfully for many years to come.

Step by step replacement

1. We drive onto the overpass.

2. Unscrew the four bolts securing the crankcase protection.

3. Unscrew and remove the engine splash guard. It is secured with several bolts.

4. Unscrew the drain bolt. Prepare containers for used oil in advance.

Before unscrewing the plugs, the engine needs to be warmed up.

5. Unscrew the nineteen bolts securing the crankcase cover.

6. After unscrewing the fastening bolts, the crankcase cover cannot be easily reached. The beam is in the way.

7. In order to remove the cover, you need to unscrew two engine mounts. The first airbag unscrews from under the hood on the left side. The other one is from under the car, through the hole in the beam.

Next, we raise the car 10-12 centimeters, go to the pit and place a wooden block under the gearbox. We lower the car and it turns out that the body will lower, and the engine and gearbox will stand on a block. Please note that you do not need to lift the car higher than 10 centimeters; if you lift it higher, you can bend the fuel pipes when you lower it.

8. Remove the crankcase cover and the old gasket, usually it sticks to the block.

9. Install a new gasket on the base of the pallet, seat the gasket on the sealant.

10. Coat the upper part of the gasket with sealant and install the crankcase cover in place.

11. Secure the crankcase cover with nineteen bolts.

12. Remove the stand from under the gearbox and screw on two engine mounts.

13. Tighten the drain plug in the crankcase cover and fill in new oil to the level.

14. Install and secure the mudguard, as well as the crankcase cover protection.

Video lesson

You can replace valve seals (oil seals) with your own efforts, without removing the cylinder head. Even a novice car enthusiast can do this, without the help of professional car mechanics.

Purpose of valve stem seals VAZ-2107

When the car engine is running, parts of the gas distribution mechanism are constantly in motion. In order to reduce friction, oil is supplied to them, which can seep through the gaps into the combustion chamber of the engine. To seal the gaps and protect the internal combustion engine cylinders from external influences, caps are placed between the guide bushings and valve stems. They are also called valve seals or seals.

Oil scraper cap device

The design of the valve seal is quite simple and consists of the following elements:

• Ostova. The steel bushing serves as a strong frame for the seal.
• Pressure spring.
• The rubber part that fits tightly to the stem.

The cap consists of these elements

In Soviet times, the rubber element of the oil seal was made from fluorine-containing polymers (fluoroplastic), which were not durable. Currently, wear-resistant valve cuffs are produced from rubber and its derivatives, resistant to aggressive influences.

When should the oil seal be replaced?

During operation of a car engine, valve seals are constantly exposed to temperature, oil and exhaust products. This leads to natural wear of the rubber part and weakening of their springs. The resource of high-quality cuffs is designed for 100 thousand kilometers.

If the car has not been used for several years, then before using it it is also necessary to replace the caps - they have dried out during the period of inactivity.

Signs of seal wear

Deformation of oil seals can be identified by the following signs:

• The color of the exhaust smoke becomes white, blue/gray.
• Oil consumption increases sharply - more than 1 liter per 1 thousand kilometers.
• Spark plugs become covered with soot and carbon deposits.

These signs may also require checking the cylinder-piston group or the entire gas distribution mechanism.

If worn valve seals are not replaced in time, then due to loss of tightness on the cylinders, valves and pistons, carbon deposits will form and the pressure will decrease. The power unit will begin to stall at idle or lose power, and will soon require major repairs.

How to replace valve seals on a VAZ-2107 yourself

Let's consider replacing valve seals using the example of a Lada 2107 equipped with a carburetor internal combustion engine.

Required tools and accessories

- standard set of garage keys;

— a device for dismantling valves (depressurizer);

- tweezers or magnet;

Step-by-step replacement of valve seals

Replacing valve seals begins with dismantling the timing shaft. This process is described in detail here. After completing the dismantling work, you need to unscrew the spark plugs.

The crankshaft is set to the TDC position of the first and fourth valves - they are kept from falling into the cylinder by the pistons, and the seals can be replaced on them.

To ensure that the valve is “closed” after drying, insert a tin (or other soft metal) rod into the spark plug hole.

A rod of tin or other soft metal

This is how the desiccant is fixed

Special tool for removing oil seals

We perform pressing using this mandrel:

After installing new seals on the valves, you need to return the camshaft to its place.

1. Install the bearings, put washers on the studs, and tighten the housing mounting nuts.
2. Align the mark on the crankshaft sprocket with the block mark.
3. Install the gear to the camshaft.
4. Return the chain to the shaft pulley and tighten the sprocket mounting bolt. Adjust the chain tension level.
5. Adjust the valve mechanism clearances. Install the distributor caps, cylinder heads and air filter.

Replacing the cylinder head cover gasket of a VAZ 2107

The valve cover gasket (cylinder head cover) is a layer of sealing material that performs the following functions:

• reliable fastening of the cover to the cylinder head;
• protection of the valve block from aggressive elements, dust, dirt;
• sealing the space under the cover, preventing oil leaks.

The following materials are used to produce valve cover gaskets:

1. Rubber. The material is elastic, but due to temperature changes it changes its characteristics - it “dumbs” in frosty weather, and softens in the heat. The rubber gasket does not last long.
2. Rubber with the addition of cork or other porous fillers. Such a gasket has high sealing characteristics, but it must be installed very carefully. Often, during installation, the rubber-cork gasket is treated with liquid sealant.
3. Paronite (asbestos or non-asbestos) is a rubber material with mineral additives that has been molded and vulcanized. Paronite gaskets for cylinder head covers are the most common today. They seal well, are resistant to aggressive influences and are relatively durable.
4. Cardboard. The material for valve covers undergoes special treatment and is resistant to water, oil, gasoline, etc. They are characterized by the least durability.

Signs of valve cover gasket wear

— presence of coolant or oil stains at the junction of the cover and the block head;

If the "seven" engine is covered with oil smudges, then it is necessary to replace the valve cover gasket.

Tool

1. 10mm socket head.
2. Collar.
3. Dry rags, rag.

Step by step replacement

1. Remove the air filter and unscrew its housing.
2. Disconnect the throttle valve drive.
3. Unscrew the cover fasteners and remove the washers.
4. Remove the cover from the studs. Remove the old gasket. Carefully wipe the joints with the new seal, removing any dirt.
5. Install the new gasket exactly and carefully place the cover in place.
6. Tighten the valve cover fasteners.

The previously removed parts are installed in the reverse order.

How to avoid engine damage in the event of a sump failure

Let's start with the fact that the damage listed above threatens not only passenger cars, but also vehicles with increased ground clearance (city crossovers and SUVs).

At the same time, one of the most serious problems, along with dented sills or various problems with the chassis, can be considered a situation when, for one reason or another, the engine sump was broken.

It is important to understand that this malfunction can cause the car’s engine to fail in a matter of seconds, and its restoration will require expensive repairs or even a complete replacement of the internal combustion engine with a contract engine. First of all, you need to take into account that it is strictly prohibited to continue driving a car with a broken pan.

The fact is that the pan itself on most cars is a kind of reservoir for engine oil (an exception is a system with a dry sump)

First of all, you need to take into account that it is strictly prohibited to continue driving a car with a broken pan. The fact is that the pan itself on most cars is a kind of reservoir for engine oil (an exception is a dry sump system).

From the sump, the oil pump of the lubrication system constantly takes in lubricant, after which it supplies engine oil under pressure to the loaded rubbing elements and components inside the power unit.

It is quite obvious that the engine oil will simply leak out even through a minor crack in the sump, and without the proper amount of lubrication, the oil pressure will drop, oil starvation will begin, as a result of which the engine will be subject to severe wear. If the leak is strong, then the power unit can completely jam in just a few minutes.

In view of the above, the following recommendations must be adhered to:

• If, while driving, there was a collision with any obstacle or the driver felt an impact in the area of ​​the front axle of the car, then the load should be removed from the internal combustion engine as quickly as possible (release the gas, reduce the speed, lower the engine speed to the minimum, stop car and turn off the engine).
• Then you should open the hood and carefully inspect the car engine from above and below. When inspecting the upper part, you should check the integrity of the engine mounts and their fastenings, inspect the internal combustion engine for fresh leaks at the gasket locations, etc. As for the lower part, it is highly advisable to find the place where the blow directly fell.

As already mentioned, most cars have a “wet” sump that contains the oil. In this case, the pan is conditionally the lowest point of the motor. It is necessary to carefully inspect the specified pallet for cracks, strong dents, fresh chips, etc. If there is no oil leak, then you should just remember where the impact point is.

Then (only if there are no strong and extensive dents on the pan) the engine can be started, after which you need to evaluate the operation of the power unit for extraneous noise, knocking, etc. You also need to make sure that the emergency oil pressure light on the dashboard does not light up. If everything is in order, you can continue driving on your own.

At the same time, in the future, you still need to visit the service station, showing the specialists the area where the impact occurred. The fact is that this place may need to be further strengthened, since next time even a slight blow to the pallet can lead to the formation of a large split, etc.

So, if a strong dent is visible, but there is no leak, or a crack was found in the oil pan through which engine oil flows with varying degrees of intensity, then the engine cannot be started. In this case, it is necessary to replace or repair the broken engine crankcase.

Types of engine protection

Depending on the material used to make the protection, there are several types of engine sump protection.

• Structural steel . It is the most excellent option for any car, which is achieved by the presence of stiffeners. In addition, the steel from which such protection is made has good elasticity, which allows it to return to its original shape after deformation.
• Aluminum . Unlike steel, aluminum protection does not have stiffening ribs stamped on it, but this does not prevent it from being a worthy competitor to steel, the weight of which is much higher than that of aluminum. Aluminum protection is quite expensive.
• Plastic . Usually, it is made of carbon, Kevlar, carbon fiber, etc. It has a fairly low weight, but is significantly inferior in strength, since it usually crumbles upon impact.

How to disassemble a generator in a VAZ-2107

To quickly disassemble the VAZ-2107 device you will need the following set of tools:

• open-end or socket wrench designed for 19;
• ratchet equipped with an extension;
• heads size 8 and 10;
• hammer.

After they are unscrewed, follow these step-by-step instructions:

1. Turn the unit over and lightly press the ends of the bolts. Your task is to ensure that the fastener heads penetrate between the pulley blades; this is the only way to secure it in a stationary state.
2. Armed with wrench 19, unscrew the pulley fixing nut, securing the VAZ-2107 generator well in a stationary position.
3. Next, separate the 2 parts of the device; this is easy to do if you tap the ear of the fastener with a hammer. You should have two parts left in your hands: the rotor and pulley, as well as the stator and winding.
4. There is a pulley in the rotor that needs to be removed by pulling it towards you.
5. Be vigilant - after removing the pulley, the key is no longer fixed and may get lost, so remove it carefully and set it aside for now.
6. Pull out the rotor with bearing. If you need to replace the old rotor with a new one, now is the time to do it. A new device costs 350 rubles in auto stores. If you need to replace the winding and stator, then you will have to pay a little more - 400 rubles.

Replacing the oil pan and its gasket on a VAZ 2101-VAZ 2107

Welcome! Today, many people already know such a thing as an oil pan, but not everyone knows what it really is, when it needs to be changed and how to properly replace it on cars of the “classic” family - we will look at these questions today.

Note! To replace the pan and its gasket, you will need to prepare a few things in advance: First, be sure to stock up on wrenches, or you can use an extension, universal joints and sockets instead!

Where is the oil pan and its gasket located? The pan is located at the very bottom of the car engine; unfortunately, in order to fully see the pan it is necessary to remove the crankcase protection, which is done in the figure below:

Note! The blue arrow indicates the gasket that is located between the cylinder block and the crankcase pan!

When do you need to replace the oil pan and its gasket? The pan must be replaced if it is deformed, due to which the engine oil that was located in it begins to flow out of the pan itself.

The pan gasket must be replaced if it is strongly compressed and if it is torn, how do you understand this, you ask? Usually, when the gasket is deformed, engine oil begins to flow through it, but the leak can also be treated by simply tightening the bolts that secure the oil pan, but if tightening the bolts does not produce any results and the leak does not stop, then replace the gasket with a new one.

Necessary tool

To clean the breather on a VAZ engine, check and replace the hoses, you don’t need any special skills or specialized equipment; a standard kit is enough. To complete the work you will need:

• set of keys No. 7-13;
• flat and Phillips screwdrivers;
• washing liquid, kerosene will do;
• container where washing will take place;
• rags;
• breather gasket;
• heat-resistant silicone-based sealant;
• if necessary, a set of new hoses will be required - separately for the carburetor and injector.

This tool can be found in any garage, so there are no problems with its selection. It is better to take rags that do not separate into individual elements, since during washing they can get into the engine.

Repair

Removing the oil pan is a fairly simple procedure, which is performed after first hanging the car on a lift. During its implementation, the specialist inspects the condition of the pallet and its internal part, after which a decision is made on the advisability of replacing it. It goes without saying that if the source of the oil leak is the gasket, the pan will not need to be replaced. The entire removal and installation procedure takes about an hour.

At the same time, installing the oil pan in place is a more labor-intensive operation, since it requires careful adjustment and careful tightening of the bolts. It should be noted that during the procedure, regardless of its tasks, it is necessary to replace the gasket, as well as the oil in the vehicle’s power unit. In addition, it would be useful to install engine protection on the car in order to protect the sump from possible damage.

What problems most often arise

Despite the decline in quality indicators, the body of the “seven” was subject to corrosion in the third year in certain places. These are the sills, supports, side members and wings, since the elements were not hot-dip galvanized.

The front and rear parts of the VAZ 2107 body are protected by a metal bumper, but after an impact, loads are transferred in waves to the bottom, as well as to all base elements, this leads to the formation of cracks in the protective coating. When moisture gets in, the bottom begins to rust both inside and out.

The most common problems with the bottom of the VAZ 2107 model range:

1. It ages quickly from dynamic loads when driving on uneven roads.
2. The first spots of corrosion are in cavities and closed pockets.
3. If the bottom of the VAZ 2107 is not treated with an anti-corrosion coating, then the machine steel sheet used for the body loses 0.2 mm per year.
4. Welding seams, bolt attachment points, sills, fenders are the most vulnerable elements.

Bottom repairs are carried out both with and without welding, depending on the degree and depth of corrosion.

Product quantity

Buy motor oil only in specialized stores for car enthusiasts, otherwise you risk spending your money on a low-quality fake, which will have a very negative impact on the operation of the car’s engine. In this case, you need to know how many liters you need to use.

The VAZ 2107 engine, type injector and carburetor, holds about 4 liters (according to experienced car enthusiasts, approximately 3.75 liters). No one can say exactly how much it will be consumed by the machine, since leaks are always possible. That is why it is necessary to have a couple of liters in reserve so as not to get into an unforeseen situation.

System assembly

After cleaning the breather is completed, you need to assemble the crankcase ventilation system. When installing the glass in place, you need to carefully align its tube with the seat. Next, a pin is screwed in, which is tightened with an open-end wrench to 13.

Before installing the breather cover, a paronite oil pan gasket is placed on the seat, which prevents gases from escaping from the system. After each disassembly of the breather, it is better to replace it, additionally treating the seating area with heat-resistant silicone, which will increase the reliability of the connection. The breather is put with a cut on the hole in the glass tube to form a channel for installing the oil level dipstick. A washer and a special nut with a rounded head are put on the stud, which is clamped with a wrench; when tightening, you do not need to pinch the nut so as not to strip the thread.

After this, the hose is put on the carburetor and the main hose. It must be inspected first, and if it is cracked, it is better to replace it with a new one to avoid excess air being sucked in. At the entrance to the air filter or in the hose itself, experts advise placing a special metal brush called a flame arrester.

It retains oil well, which may be contained in crankcase gases and enter the air filter, clogging it. As a result, the quality of the air-fuel mixture decreases and engine stability is lost. This is especially important for cars with high engine mileage; used oil and emulsion are deposited on it and flow back into the crankcase. When choosing this part, it is better to consult with specialists so that the wire from which it is made is of high quality and does not break, getting into the crankcase.

Possible faults

Malfunctions of this part do happen, and it is dangerous to ignore them, since loss of oil threatens serious and expensive repairs of the internal combustion engine. They can be easily diagnosed by oil leaks - a characteristic small puddle that remains on the asphalt after an overnight stay and a wet sump. The causes of leaks may be:

• loose oil pan bolt;
• gasket wear;
• loose drain plug;
• cracks in the metal.

Cracks in metal are a much more serious problem than a poorly tightened bolt. They can appear as a result of impacts with large stones, curbs, etc. Even if protection is installed under the crankcase, it can crack due to non-compliance with the bolt tightening torques recommended by the manufacturer. A crack can also occur if the drain plug is overtightened after an oil change or repair. It has a slightly conical shape, is made of a harder metal, and can tear the pan. Such a crack is difficult to see, and some service workers, trying to eliminate the leak near the plug, tighten it even more, which subsequently aggravates the situation.

Replacing the oil pan gasket

Replacing the oil pan gasket

The work associated with replacing engine seal parts is quite labor-intensive and requires a lot of time and effort. But what can you do, the car requires care and attention, such is the lot of every car enthusiast.

If you notice that oil leakage has appeared around the perimeter of the oil pan mounting to the cylinder block, try to eliminate the leak by tightening the mounting bolts. When tightening, the bolts should be pulled smoothly, since excessive force can lead to pulled threads or tearing off the bolt head, which entails additional repairs (you may have to drill out the bolt or re-thread the cylinder block, which is extremely inconvenient in cramped conditions).

After tightening the bolts, you again find oil leakage; you need to replace the oil pan gasket. In exceptional cases, it is possible to eliminate a leak using a sealant (this is if, for example, you are on the road and you do not have the opportunity to replace the gasket with a new one). Next, you will need an inspection hole or a lift, and you will also need a tool. A set of 10.13 socket heads, universal joints, and a long adapter is best suited.

1. Remove the shield protecting the crankcase.

2. Next, you need to drain the oil from the engine, unscrew the oil plug from the valve cover, which is located on top of the engine, thereby ensuring air access necessary for normal oil drainage, prepare a bucket or any suitable container, unscrew the lower oil plug on the crankcase, and completely drain the oil.

3. since, due to the limited distance, you will not be able to remove the crankcase, you will need to lift the engine, to do this you need to unscrew the nuts securing the engine mounts on the right and left sides.4. It is possible to lift the engine using two devices: a manual hoist and a cross beam. Next, we will describe the method of lifting the engine using a traverse. Having installed the yoke, lift the engine by about 3 cm; to do this, you need to turn the nut in the middle of the yoke.5. It is necessary to lift the engine so that the pins do not come out of the bracket holes.6. Carefully, so as not to lick the edges on the bolt head, use sockets or a spanner and unscrew the crankcase mounting bolts.7. Using a screwdriver, pry up the oil pan and separate it, together with the gasket, from the cylinder block. If any gasket residue remains on the cylinder block, you must remove them with a sharp object or a knife, without leaving scratches on the attached surface.

8. Before replacing the oil pan gasket with a new one, it is recommended to remove any remaining oil from the attached surfaces of the oil pan with a clean rag. cylinders and oil sump. Next, apply a thin layer of silicone sealant to both sides of the new gasket. Install the gasket on the pallet, tighten the bolts, and, pressing the pallet to the block. cylinders, crosswise without using excessive force, tighten the bolts, assemble all the early removed parts in the reverse order of disassembly.

Replacing the oil pump

To replace the VAZ 2106/07 oil pump, the car should be placed on a lift, inspection hole or overpass. In extreme cases, you can use a jack.

Necessary tools and equipment

To replace the oil pump you will need:

• set of socket wrenches;
• knife;
• jack;
• durable wooden block;
• wooden spacer;
• container for draining oil;
• new oil pump gasket;
• new pan gasket;
• new oil pump.

Oil pump removal procedure

The oil pump is replaced as follows:

Clean the bottom of the engine from dirt. After unscrewing the protection fastening, remove it.

When replacing the oil pump, it is necessary to remove the crankcase protection

The oil drain plug is unscrewed with a hex wrench

To disconnect the engine from the body, you need to unscrew the nuts securing the lower supports

The engine is lifted using a jack and a wooden spacer

To dismantle the pallet you will need to unscrew the mounting bolts

The oil pump is removed along with the gasket

Oil pump installation procedure

Installation of a new or repaired pump is carried out as follows:

1. Install a new pump with a new gasket.
2. Tighten the pump fastenings.
3. Reinstall the pan cover along with a new sealing element. Tighten all mounting bolts evenly.
4. Lower the engine and install the supports in place. Tighten the fastening nuts.
5. Install and secure the crankcase protection.
6. Fill with new engine oil.

Greetings to all colleagues, in an unequal fight against the dark side of unfinished components in our machines =)

Preface... I went to work early in my life, from the age of 15, I didn’t like any science, I didn’t want to study)))) I immediately went and got a job in a convoy with passenger buses, taxis and cargo equipment. In exchange for my studies, I began to comprehend the technique, so to speak, experimentally in practice, right on the battlefield, so to speak))) But then I also went to study at the same time, where would I be without theory =) And when it came to the point of changing the repair oil in a bus engine, for example, when you unscrew the drain plug to drain the used oil, there was a magnet on the plug! This magnet collected fine shavings from the production of various parts of the internal combustion engine. My duties included cleaning off this “hedgehog” of shavings and screwing them back in, pouring in fresh oil, etc. In gearboxes or axles, transfer cases, there were also such plugs, with the same magnets, and the same functions)

And now thorium) With such plugs, the service life of the internal combustion engine increases, since metal shavings are caught by a magnet, which could get into rubbing areas, and like lapping paste or a file, would increase friction and, accordingly, the production of the same journals of the crank mechanism, which quickly leads to engine overhaul. Naturally, we don’t want this, so I thought, why did the VAZ auto engineers miss this, well, it’s not so much perfect metal or some other technology) And I decided to introduce neodymium magnets into our drain plug! But before doing this, I got rid of our standard plug, it has a problem, no matter how you tighten it, it still leaks, and there is nothing to do about it:
