Hello, dear blog visitors and readers. In this article we will look at how to eliminate oil leaks from the gearbox on your own. There is nothing complicated, and it all depends on the wear of the mechanism and the complexity of the damage. Most gearbox oil leaks come from seemingly insignificant transmission components. Many have fallen into disrepair or been damaged.

Oil leaks from the gearbox occur regardless of the age of the car. The driver's driving style and timely maintenance of the car are affected. There is no need to remind you of the danger of oil deficiency for the gearbox.

The friction force between transmission elements increases, which leads to a reduction in service life. Malfunction of the gearbox will reduce the efficiency of the vehicle. Transmission repair costs caused by oil shortages hit the car owner hard.

At the end of the article you can find an interesting and entertaining video on how to fix an oil leak from a gearbox. It will help you quickly resolve the problem and stop transmission oil leaks.

Easy to fix oil leaks from the gearbox

An attentive driver who cares for the car can quickly detect an oil leak. Measurements are taken of oil droplets on the asphalt surface. The appearance of oil indicates that there is a problem that needs to be solved. Ignoring the problem in the future will cost a lot of time and money.

Oil leaks appear on the surface of the gearbox housing. If you don't look closely, they are hard to notice. As the amount of oil increases, droplets appear.

After parking the car, small black oily puddles form on the asphalt. You need to drive the car onto a viewing hole or lift. It will make it possible to quickly find the location of the leak and fix the problem.

Cleaning the crankcase ventilation system | Repair of VAZ 2110

The crankcase ventilation cleaning system on VAZ 2110-2112 vehicles is designed to remove crankcase gases. This system has three hoses:

1. One is the so-called breather, which runs from the bottom of the cylinder block to the valve cover.
2. The second is connecting the valve cover and the thick inlet pipe (air filter)
3. The third - the thinnest - goes from the valve cover to the throttle body

If this system is clogged, problems may arise such as: constant leakage of oil from under the gaskets and seals of the engine, release of oil into the air filter bellows, and contamination of internal engine parts beyond the norm

To avoid this, it is necessary to regularly clean the ventilation system. In addition to checking all hoses for integrity and contamination, be sure to clean the screens that are located under the oil separator housing in the valve cover.

To do this you will need a 10mm socket with a ratchet and an extension, as well as a Phillips-blade screwdriver:

The first step is to remove the valve cover. After this, on the inside you can see two oil separator mounting bolts that need to be unscrewed:

Then remove the cover, as shown in the photo below.

And take out the block to the mesh, which is located under it:

Pay attention to their condition. Usually, if no one has ever cleaned them, you can see something like the following picture (mileage over 150,000 km).

What is an engine breather and why is it needed?

Everyone knows that the internal combustion engine, the same one that is installed under the hood of your car, does not run on gasoline, diesel or gas, but on their mixture with air. Moreover, it is air, which costs nothing (unlike fuel, for which we regularly pay a tidy sum at the gas station), that is required many times more. But in addition to the influx of clean air and the removal of exhaust gases through the exhaust pipe, parasitic gases are formed during the operation of the internal combustion engine.

A breather is nothing more than a breathing valve that constantly relieves excess pressure that forms inside the engine during operation. The need for this simple, relatively inexpensive part is difficult to overestimate.

Difficult to eliminate causes of oil leakage from the gearbox

To eliminate an oil leak, you will have to spend time and sweat. The reasons require the participation of car repair specialists, but if you set a goal, you can cope without them.

Replacing oil seals.

If the obvious causes of oil leakage have been eliminated, but leaks continue to appear with enviable frequency, the seals are examined.

Special rubber seal in a metal frame. Serves to prevent leaks and oil on the moving elements of the engine and gearbox.

Long-term use of the oil seal wears out the rubber base. Oil pressure does not hold. If the oil seals have been replaced recently, you need to think about the quality of the oil used.

The replacement procedure is as follows:

• oil is drained;
• the wheel bearing mount is dismantled;
• the bolts securing the ball joint are unscrewed;
• the steering knuckle is retracted;
• the axle shaft is dismantled;
• remove the oil seal using a regular screwdriver;
• Before installation, the oil seal is lubricated with oil;
• Installation of the cuff is carried out by lightly tapping the hammer through the mandrels.

Why does oil squeeze out through the breather: how to fix the problem

A fairly common problem on many domestic and foreign-made cars is that oil flows through the breather. In winter, especially with the onset of significant cold weather, you can encounter a malfunction when the breather freezes, oil is squeezed out and streaks are visible on the outer surface of the power unit. Let us immediately note that this symptom, as well as smoke and oil from the breather, are a reason for immediate engine diagnostics, since ignoring this problem can lead to quick and expensive engine repairs.

Note that if there is oil coming through the breather, diagnosing the root cause may be difficult. To accurately determine the underlying problem, skills, special equipment, etc. will be required. However, in some cases, the driver can understand why oil is leaking from the breather without the involvement of third-party specialists. In other words, diagnostics are carried out independently in a garage environment. In this article we will talk about why oil drips from the breather, as well as what a car owner should do if oil comes out through the breather.

Breather oil: what to do and how to find the cause

Let's start with the fact that during engine operation, so-called crankcase gases accumulate in the crankcase. To prevent excess pressure from being created, there is a special valve for ventilation. This solution allows the closed crankcase to communicate with the atmosphere. This valve is the breather. In simple words, a breather on an internal combustion engine is actually needed to equalize the pressure inside the engine.

It should be noted that in the crankcase gases mix with oil mist. As a result, lubricant particles enter the breather. Although there is a special oil trap inside the device, a certain part of the oil may escape out. Given this information, minor contamination of the system is acceptable, which is normal. In cases where a lot of lubricant leaks, you should look separately for why oil is leaking from the breather.

Replacement

Replacement is carried out in a certain order. This will be discussed below.

Diagnostics

Replacing drive seals on a VAZ 2109, 2108 usually begins with determining the location of the oil leak, the degree of wear and damage to the drive seals. This degree of wear can be determined by oily streaks that appear on the gearbox housing and, during long-term use, look like spots of greasy, non-drying dirt.

Advice! Replacing drive seals on VAZ 2108, 2109 should first begin with checking the breather, since the lack of ventilation in the gearbox is the main reason why oil is squeezed out through the side cuffs by crankcase gases.

Dismantling

Replacing drive seals for VAZ 2109 and VAZ 2108 involves removing the drives and draining the oil from the gearbox , so we will need... Tools:

• Keys for seventeen and thirty (with a long knob);
• Container for drained oil (volume of at least three liters);
• Installation;
• Screwdriver;
• Tools for pressing in a new oil seal (hammer and mandrel)

Of course, in order to press in a new oil seal, you can use the body of the old one, but, believe me, this is not very convenient, so it is advisable to select the necessary mandrel according to the diameter of the oil seal, for example, by taking a suitable piece of pipe for this.

In arctic conditions, a simple crane from model 2108 is more reliable.

In Arctic conditions, a simple faucet from model 2108 is more reliable. In Arctic conditions, a simple faucet from model 2108 is more reliable.
For many, shock absorbers work, as they say, until the bitter end - until they completely leak. Of course, you shouldn't wait for this. Body sway and loss of trajectory stability already by 60,000 km (a very worthy resource!) became quite noticeable, and we replaced the shock absorbers. Instead, they supplied SS20 products from System of Technologies. These, working to this day, do not knock, do not leak, and with them the car holds the road well.

The battery, after serving for three years, stopped accepting a charge. The reason is simple: the charging voltage is low - about 13.9 V, and even less when the headlights are on. The battery, remaining undercharged, quickly sulfates, and it is not always possible to “boost” it to its nominal capacity. Therefore, having bought a new one, we built a diode into the voltage regulator circuit, raising the voltage to 14.5 V. Since then, the battery has served faithfully.

Once, while traveling in the winter Arctic, the climate control failed - the heater damper drive burned out. There are no spare parts, and in the cold you can’t do much without a stove. We had to look for a solution. First of all, we forcibly opened and locked the damper. Heat entered the cabin, and its excess was dumped out the open window. The next day, the mechanics of an unknown service station cut a tap from a G8 into the heater hose, and its drive—a choke cable from a Lada—was brought into the cabin under the steering column.

Reasons for changing transmission oil in a VAZ 2109 gearbox

Replacing the transmission fluid in the “nine” box may be necessary for the following reasons:

• When extraneous sounds and creaks appeared. Gradually, the liquid loses its properties, and particles of metal and moisture can get into it. In turn, this leads to accelerated wear of parts.
• If the transmission fluid has become dark or black in color, it should be replaced regardless of the vehicle's mileage.
• Purchasing a used car. Especially when it is unknown how long ago the former owner changed the fluid.

The dipstick, which has 2 max and min marks, will help you find out the level of transmission fluid in the VAZ 2109 gearbox - you need to add it if the level is below the min mark

VENTILATION DESIGN FEATURES, OPERATING PRINCIPLE

The simplest diagram of the crankcase ventilation system used on internal combustion engines previously consisted of only one fitting - a breather installed in the crankcase. This breather connected the internal cavity of the cylinder block with the external environment, and crankcase gases simply escaped through it into the atmosphere. But this scheme had one significant drawback - the exhaust gases contained oil particles, which also entered the external environment. And this is not only loss of lubricant and the need for periodic refilling, but also air pollution. On modern cars the ventilation system is closed. It also has a breather, but a pipe is connected to it, allowing gases to be vented into the intake manifold or air filter housing, from where they enter the cylinders and burn. That is, the atmosphere is not polluted by them. Additionally, the system includes elements that ensure oil separation and return back to the crankcase so that it does not enter the cylinders along with the gases.

There are several options for oil separators, and on cars from different manufacturers they may differ in design and operating principle. It is worth noting that part of the exhaust gases enters the supra-valve space, and they must also be removed. Therefore, the entire circuit of the engine ventilation system on a modern car consists of a breather, an oil separator and two pipes. Additionally, a special valve can be included in the system to regulate the pressure of gases entering the intake manifold. The configuration of the system can be very different, but this does not change its purpose and operating principle. For example, consider the ventilation design of the VAZ-2110. At the bottom of the cylinder block of this car there is a breather, onto which a pipe is attached; the second end of this hose is connected through a fitting to the cylinder head cover. At the same time, an oil separator is located inside this cover at the inlet of the pipe. On its other side there is another fitting, to which a tube is connected that goes to the air inlet pipe.

The principle of operation of such ventilation is simple - gases enter the cylinder head cover space through the breather and pass through the oil separator, while the separated oil flows to the valve assembly. After this, the gases are mixed with those that have broken into the supra-valve space and are supplied to the air pipe, and then to the manifold. There is no pressure regulating valve in this car. On other machines, the oil separator may be located immediately next to the breather, and a valve is installed behind it.

Let's sum it up

Taking into account the above information, it becomes clear that even with its apparent simplicity, the breather of a gearbox, engine or axle performs a rather important function. This means that the condition and proper operation of this element must be monitored.

This is especially true for SUVs, trucks and special equipment, where in addition to gearboxes and internal combustion engines, breathers are installed on bridges. Such machines are often operated in harsh conditions, as a result of which the gearbox or axle pressure reduction valve may become dirty or fail more often (especially the rear axle breather).

Engine tuning

Since the 21128 engine is already a boosted version of the 21126, the possibilities for increasing power are limited:

• The piston stroke is already “long”, if you additionally bore the cylinders, it will take a long time to select a suitable ShPG and crankshaft;
• a new design receiver is already installed on the intake tract, but it is possible to install a “zero” air filter and a damper with a cross-section of 54 mm, a “spider” on the exhaust manifold instead of the standard one, this will bring the power closer to 130 hp. With.;
• tuning is possible by turbocharging the internal combustion engine - PK-23-1, cylinder head gasket from the 2112 engine, Nuzhdin 8.8 camshafts, channel cutting, Bosch 107 injectors and 51 mm exhaust pipe.

Thus, before buying a car from Super-Auto with a 21128 engine, you should seriously think about whether it is worth choosing such power, overpaying for road tax and insurance, being content with a resource of just over 100,000 km. In addition, the pistons are not protected from “meeting” the valves, despite the Gates belt with a service life of 200,000 km.

How to replace gearbox seals

At the same time, as practice shows, if the gearbox has not experienced shocks, and the wear of the unit itself is not too great, then most often the culprit is the gearbox seals. Below we will look at how to replace them.

Often the seals (cuffs) in the gearbox are placed on the input shaft, there are also axle shaft seals, and there is also a gear selector rod seal. To replace drive shaft seals, you will need:

• drain the oil from the gearbox;
• Unscrew the wheel bearing nut and the ball joint bolts;
• Next you need to move the steering knuckle towards the side;
• dismantle the axle shaft and remove the old oil seal (removed with a flat-head screwdriver);

Before installation, the working surface of the oil seals must be separately lubricated with oil, and the installation itself must be performed by carefully and lightly hitting the spacer (mandrel) with a hammer.

If oil leaks as a result of wear of the cuff of the gear selector rod on machines with a manual transmission, then the oil seal is replaced as follows:

• at the initial stage, you need to unscrew the screw securing the gear shift drive hinge, then disconnect the element from the rod;
• then the protective cover of the hinge is removed, the oil seal is removed with a screwdriver;
• then you will need to install a new cuff, striking through the spacer, while the oil seal must first be lubricated with oil.

We also note that often experienced owners of cars with front-wheel drive, if this is possible, recommend additionally installing one or two more similar oil seals on top of the gear selector rod oil seal, between which a layer of sealant is placed.

To gain access to the oil seal, you need to remove the release bearing bushing. The oil seal is removed with a special hook, and installation is performed by tapping it with a hammer through a mandrel.

Components

In fact, this is a large plastic jar with activated carbon inside, because it is this composition that perfectly fights gasoline vapors. The main parts can be described as follows:

• Separator + gravity valve
• Pressure meter
• Filter part (usually carbon)
• Connecting tubes
• Solenoid valve

As you can see, there is absolutely nothing complicated. Separator - serves to catch part of the gasoline, then sends it back to the tank. Gravity valve - almost never used, but it is needed in emergency situations, for example during accidents, it prevents fuel from overflowing from the tank (for example, when a car overturns).

The pressure sensor is a very necessary thing - it monitors the pressure of gasoline vapors inside the tank, if necessary, it opens and resets it, preventing the structure from being damaged.

The filter part is, as I wrote above, a large jar into which coal powder is poured, in fairly large granules. This is done so that vapors can pass and condense freely.

Connecting tubes are needed to connect all the main parts, filters, sensors and valves, I think this is clear.

Solenoid valve - used to switch modes for capturing gasoline vapors, we will talk about it in more detail below.

Breather VAZ 2110 2112 2114 2115 2109

Publication date Jul 08, 2014, Categories Spare parts for VAZ |

The breather of the VAZ 2110 2112 2114 2115 2109 “makes itself felt” when the oil seals in the car’s power unit begin to leak. Also, the cylinder head gasket may be squeezed out. If such problems are observed, therefore, it is necessary to remove the cylinder head from the engine and pay urgent attention to the technical condition of the power unit breather. The VAZ engine breather is a screening element whose task is to ensure the passage of gases that accumulate in the cylinder block under the valve cover, on the one hand, and on the other, to block access for the return passage of engine oil.

It is worth drawing the attention of motorists to the fact that the design of the VAZ 2110 2112 2114 2115 2109 breather does not present any complexity. The breather is an aluminum multilayer mesh, which is not at all intended to carry out any filtration; its task is simply not to allow access to oil. Therefore, the VAZ breather does not break, but becomes clogged, or, to put it more precisely, clogged. The reason for this may be the use of low-quality motor oil or a violation of its seasonal use; also, the failure of the breather may be caused by failure to comply with the vehicle maintenance regulations, including changing the oil and oil filter. One way or another, the technical quality of the oil and the proper operation of the VAZ 2110 212 2114 2115 2109 breather are indivisible factors.

During the operation of the VAZ 2110 2112 2114 2115 2109 engine, excess low-quality oil settles in the breather, gradually transforming into fuel oil, which finally clogs it. Partly, this happens due to changes in temperatures in the car’s power unit. As for gases, their excessive pressure, which is formed as a result of combustion of the combustible mixture and is accompanied by very high temperatures, ensures their accumulation under the engine cylinders, which leads to squeezing out and leaking of the aforementioned oil seals and cylinder head gaskets. The breather in VAZ cars is designed to remove these gases, which is not a difficult task, but extremely important for the normal functioning of the car’s power unit. All of the above factors force you to once again pay attention to the brand of motor oil that your VAZ vehicle runs on.

Cons of SVKG in Lada Priora

By cleaning the atmosphere from the emission of toxic substances, SVKG creates problems for the engine. The gases that are removed from the pan, despite the presence of an oil separator, are saturated with microscopic oil particles, which after some time leads to contamination of the fuel intake system.

This leads to engine interruptions. Gas particles settle on the valve components, which leads to its failure. This disrupts the fuel injection system into the combustion chamber and increases oil consumption. If contamination is severe, fuel injection does not occur. In this case, the valve must be completely replaced. It is necessary to periodically inspect the crankcase ventilation hoses, because under the influence of the environment they age and crack.

If you detect oil stains, an increase in the amount of oil consumption, an increase in the consumption of fuel and lubricants, as well as disturbances in the engine (stopping, does not start for a long time, makes exhaust and other uncharacteristic sounds), be sure to immediately contact a service center to have the engine checked and repaired. Timely treatment will reduce the cost of engine repairs and prolong its operation.
