Replacing camshaft seals VAZ 2114 8 valves

In some situations, it may be necessary to replace the camshaft oil seal on VAZ 2114 and 2115 (8 valves).
This is necessary if there are leaks that are best fixed immediately. Often drivers are afraid to replace the oil seals on the engine themselves, but in fact this is a completely harmless job. It can be performed even without special skills. Actually, it is very difficult to break the engine by doing such manipulations. And usually the repair is completely painless for the car and the driver. Please note that it is better to perform all actions strictly in order, this will simplify the task. Replacing the camshaft oil seal on VAZ 2114 and 2115 (8 valves) can be done in any garage. There are no particular difficulties here; all actions are performed using a minimum number of tools. Also, you will not need to make additional engine adjustments after work.

Replacement

Having prepared the necessary tools, you can get to work.

First of all, disconnect the negative terminal from the battery on your VAZ 2114.
Move the piston of the first cylinder to top dead center.
Remove the pulley from the camshaft.
The key is then removed from the camshaft.
The seal is easy enough to install. You just need to pry it off with a flat screwdriver.
Before installing the new device, pay attention to the inner edges on both sides. They should be free of all kinds of damage, dents, rubber sagging, etc.
The working edge must be lubricated with simple motor oil. This will allow the element to easily settle into a new place and also protect it from premature wear.
If problems arise with the reverse pressing of the oil seal, its seating edge can be processed with a file or fine sandpaper.
Inside the block head, the element is installed with its working edge. A regular wooden stick will help you carefully place the element in its place on the camshaft. Just do not use metal elements for pressing.
It should be pressed in until it stops.
Perform the assembly reassembly procedure.
The camshaft pulley is installed as a protruding element of the hub in relation to the power unit. Be sure to adjust the camshaft belt tension level.

At this point, the installation procedure for the camshaft oil seal can be considered complete. The most difficult stage is rightly considered to be the disassembly stage. Replacement is quite simple. Every VAZ 2114 owner is able to cope with such a task with his own hands.

Method 3

The stuck crankshaft pulley of the VAZ 2114 can be removed with some effort. Even an additional lever in the form of a pipe does not always help to remove the nut. In such a situation, you can resort to a rather tricky option for removing the spare part - using a starter. Because a working starter drives the flywheel and the pulley itself - its force can be useful for sharply unscrewing the fastener. Step-by-step instructions for removing a part in this way are simple:

After dismantling the generator and timing belts, proceed to securely fix the nut with a wrench without blocking the pulley;
The photo below shows one type of reliable fixation;
Move the gearbox to neutral;
For safety, remove the high-voltage wires from the spark plugs;
Move into the car interior and sharply turn the key in the ignition a couple of times;
Cranking the starter will cause the nut to loosen.

Before carrying out work, we also recommend treating the contact surface of the nut with a special lubricant. After this procedure, all fasteners can be unscrewed with ease.

Having torn off the nut, remove the part and carry out the necessary manipulations. When reinstalling the spare part, it is not necessary to tighten the nut with great force.

The only difficulty that arises when carrying out such a procedure: souring of the thread. Treatment with chemical lubricants only partially solves the problem, so when dismantling, use great force to successfully unscrew it.

Replacing the camshaft oil seal on a VAZ 2113, VAZ 2114, VAZ 2115

Welcome! Seals - not a single car with a gasoline engine can do without them, because they are one of the main protections thanks to which dirt does not get into the engine and oil, coolant, etc. do not leak from it, oil seals are used in many components car, for example, they are in the steering gearbox, they are also located at both ends of the crankshaft and are also present on the camshaft, due to them oil does not leak out when the engine is running and when it is stopped, as well as various kinds of dirt into the inside of the engine does not penetrate and the engine remains protected from this, but over time, any seals deteriorate and a number of problems begin, one of which is increased oil or coolant consumption in the car.

Note! In order to replace this oil seal, you will have to take with you: A screwdriver, also socket heads, as well as a wrench for them, and a set of wrenches will come in handy for all this!

Causes of malfunction

First, let's look at why the oil seal may need to be replaced. Normal wear and tear is usually the main cause. The oil seal is a rubber-metal ring that is designed to prevent leakage of lubricant under pressure. Gradually, the effectiveness of the part decreases and should be replaced.

Replacement may also be required as a result of increased oil pressure in the engine. This can cause excess oil to be squeezed out through the seals. In this case, they should also be changed. But this situation is rare for a camshaft; usually in this case the crankshaft oil seal suffers.

How to replace the camshaft oil seal on a VAZ 2113-VAZ 2115?

Removal: 1) At the very beginning of the operation, you will need to remove the timing mechanism cover and then set everything according to the marks; how to do both of these actions, read the article: “Setting the valve timing according to the marks”, in which we explained and described everything in detail.

2) Now remove the Gas Distribution Mechanism belt from the tension roller and from the pulley, again we described in detail how to do this in another article which is located on our website, and it is called: “Replacing the tension roller on a VAZ”, study point 2 in it .

3) Next, we move on to removing the camshaft pulley, we will warn you right away that it is not advisable to turn it (Especially if you have an engine that bends the valves, then with the timing belt removed, turning this pulley is generally prohibited, because the valves will definitely meet with the piston group and if If you turn this pulley too much, there will be an impact due to which the valve will bend slightly, but still bend), but if you need to turn it, do everything very carefully and think with your head while doing this (If your engine does not bend the valves, then they are piston the group will not meet in this case with the timing belt removed from the car), by the way, still try to remove the pulley (this is mandatory) in such a way that it is directed according to the marks at this moment, well, let’s get started, the first thing you need to do is So, use your hand or something else to stop the pulley so that it does not rotate, after stopping, unscrew the central bolt that secures it (see photo 1, at this time still hold the pulley with your hand) and then remove the pulley from the camshaft (see photo). photo 2), as soon as the pulley is removed, remove the key using a screwdriver by simply sliding it longitudinally (see photo 3, the key is indicated by an arrow), and then remove the oil seal itself by prying it with the same screwdriver or something else similar to her (see photo 4).

Note! When the oil seal is removed, inspect it all; the working edge, which is indicated by the letter A, must be in good condition and not damaged, there should be no dents of any kind on it, and the oil seal spring, which is indicated by the letter B, must be intact and unstretched, otherwise the oil seal must be repaired. replacement, by the way, check the new oil seal in the same way and if there is anything on it from the above, then do not install such an oil seal, but find a new one, in addition, when installing a new oil seal, the working edge of which is in contact with the shaft (It is also the letter A indicated) lubricate with engine oil (Preferably the same one you fill in the engine)!

Where is

The oil seal is located under the timing belt boot, behind the camshaft gear.

The oil seal must be replaced if engine oil leaks through it. This leak can lead to oil getting onto the timing belt, which is strictly prohibited. Oil can damage the belt and lead to its breakage, which on 16-valve engines can lead to valve bending.

Replacing the camshaft oil seal VAZ 2114 8 valves

The oil seal leaked, I decided that I would change it myself, because I was tired of leaving money for a hundred. and so there have been a lot of expenses lately - replacing the pump, thermostat, in addition, I spent 6 thousand to restore the car after it fell into an open hatch (2700 for the rear beam and 3300 for replacement work).

therefore, what I can do, I’ll do it myself, especially since all this is quite interesting, considering that there is nothing complicated in it, in fact it’s necessary

1). loosen the tension roller and remove the timing belt 2). Carefully, so as not to lose the key, unscrew the gear 3). pull out the old oil seal and, after lubricating it with oil, install a new one

I wanted to film the whole process, but to be honest there was no time for that.

the old oil seal was all oak and was pulled out piece by piece.

that’s all, except that when I unscrewed the gear, the marks got lost and then I couldn’t cope with tensioning the belt, it was dangling. but it’s good that just after that I went to a hundred (got there :)) to change the rear pads, where they tightened my belt. I had to remove the wheel. ok, the main thing is that the oil seal has been changed) by the way, replacing this camshaft oil seal costs 1000 rubles :) but it takes about 15 minutes, essentially.

Tools

It is worth paying attention to preparing all the necessary tools. This will somewhat simplify and speed up the repair process. So, you will need:

Set of heads and knobs;
Slotted screwdriver;
Spanners;
Wheel chocks;
Mandrel for oil seal.

Before starting work, be sure to set the car to the handbrake; wheel chocks will also come in handy.
This will improve work safety. Be sure to keep in mind that to replace the rear oil seal on the crankshaft, you will need to remove the gearbox. It’s better to do this in a pit, it will be much more convenient. If this is not possible, then you can simply make simple entries to gain access to the bottom of the car.

The camshaft pulley is installed as a protruding element of the hub in relation to the power unit. Be sure to adjust the camshaft belt tension level.

Method 1

The first step is to try to remove the pulley bolt using the standard method. The set of tools for this procedure is as follows: heads, spanners, jack. The step-by-step removal process looks like this:

Unscrew the right wheel and jack up the car;
Remove the plastic protection (if any);
Loosen the generator belt tension bolt and remove it;
Reach the pulley and lock it in one position;
Remove the timing belt;
Place a socket or a 19mm spanner on the pulley nut and try to tear it off;
If the fastening does not work, treat the nut with WD-40 or tap the pulley with a wooden block. Often this allows you to get rid of sticking.

This method of dismantling is considered the easiest, but it is only possible if the fastening nut is slightly soured. Remember that treating with chemical lubricants before starting work will greatly simplify the removal process.

If this method does not bring results, check out the second one.

How to replace the camshaft oil seal on a VAZ-2114

Having a passenger car, the owner must not only monitor its cleanliness, but also, first of all, its technical serviceability. Quite often, car owners notice that what comes out of the exhaust pipe is not ordinary smoke, but bluish and oily smoke, and in addition to this, oil consumption during operation of the car increases several times. This may indicate that the camshaft seals are simply worn out, and a simple replacement operation will help fix the problem for the VAZ-2114.

For many, this work sometimes seems problematic, so cars that need it are most often transported to a service station. In fact, this process is not so complicated, and if you follow the recommendations in your work and carry out the whole process step by step, then everyone will be able to replace failed camshaft seals on a VAZ-2114 16 valves with their own hands.

When is it time to change the camshaft

Emergency intervention in the operation of the VAZ 2114 8 cl camshaft is necessary in the event of any obvious malfunctions.
Signs may be different, for example, a knocking sound is heard when the engine is running or problems with the seals. You need to check what’s wrong in such a situation immediately, either on your own or at a service station. If you determine that the problem is in the seals, then 10 minutes will be enough for you to make a replacement. The oil seals are located in easily accessible places and installing a new one does not require dismantling large systems and components. If you don’t know which one you need to replace, you can check this simply by looking at which one is already installed.

New oil seal

A more complex malfunction may occur if you hear a knocking sound in the engine. This malfunction may not progress, that is, the knocking does not increase, while the readings of all sensors are normal. Some drivers take this calmly; they are not bothered by this state of affairs and continue to use the vehicle without paying attention to it. But the solution is simple: if your engine knocks, it means that the axial play of the camshaft has increased. In this case, you can put a washer between the camshaft and the cover and there is a high probability that the knocking will stop. A fairly simple way out of this situation.

Washer installation location

Some cars are equipped with camshaft position sensors, whose task is to signal in case of malfunction or malfunction of the system. But sometimes sensors fail and may need to be replaced. It is inexpensive and the price of such a sensor on the market does not exceed $10, and you can find out which one to buy from the car’s instructions. Installing such a sensor is simple, so there is no point in stopping there.

Replacing the front oil seal

It is recommended to replace the front oil seal yourself in the following sequence:

use a screwdriver to remove the oil pump;
remove the worn oil seal from the cover of the removed pump using a screwdriver;
By resorting to the frame, a new part is installed in place of the worn one. The outer size of the new element should not exceed 41 mm; during installation, the working edge should be directed inside the pump;
After making sure that the oil seal is well pressed, the oil pump is installed in its original place.

At this stage, the process of replacing the front valve that has become unusable is completed.

How to change the rear oil seal

Changing the rear oil seal will be a little more difficult, but this does not mean that a car enthusiast cannot cope with such a task on his own. The most important thing is to follow the instructions, and every car enthusiast can do the job no worse than a professional:

The negative terminal of the battery must be disconnected from the power supply.
The flywheel is dismantled. Before removing the flywheel, you need to mark its original location, taking into account the location of the crankshaft.
The rear clutch housing shield is removed from the bushings.
The fasteners that secure the oil seal are unscrewed; there should be 8 fasteners.
The holder is removed.
Next, you need to carefully remove the seal that has become unusable from the holder.
Using a mandrel with a diameter of 99 mm, the new oil seal must be pressed into place of the one just removed, making sure that the working edge of the element is directed inside the holder.
You will definitely have to replace the holder gasket, even if the appearance of the old one seems quite normal.
To ensure reliable installation of the gasket, it is recommended to use a thick consistency lubricant.
Before installing the oil seal, its working surface should be treated with engine oil; the same procedure should be done with the crankshaft flange.
It will be much easier to insert the holder of the working edge of the new oil seal onto the crankshaft flange using a wooden tool, for example, a stick of the appropriate size. But metal products are strictly not recommended for this event.
After making sure that all elements are installed correctly, you can begin fixing the holder and engine crankcase.
Next, the clutch housing protective shield, flywheel and gearbox are installed in their original place.

Experts recommend using sealant for all threaded fasteners for a more durable fixation. After reviewing this information, it is easy to come to the conclusion that every car enthusiast can replace camshaft oil seals. So why waste money on paying service station workers? Of course, this activity must be carried out step by step and very carefully, and for replacement it is imperative to purchase high-quality components so as not to repeat the entire process after a short period of time.
