The gas distribution mechanism of the engine on a VAZ-2115 car is an adjustable design, which means that periodically it is necessary to set the required valve clearance using adjusting washers. It is necessary to carry out this procedure at the slightest knock in the cylinder head or every 45 thousand kilometers.
The frequency of valve adjustment on the VAZ-2115
The manufacturer regulates to carry out these works every 45 thousand run.
But quite often it becomes necessary to adjust them much earlier, for many reasons.
This indicator is primarily due to the quality of domestic spare parts, which wear out rather quickly under ideal operating conditions.
Adjustment of valves
The appearance of a metallic knock at the top of a running engine, very similar to the sound of a sewing machine, will indicate an increased clearance between the camshaft cam and the valve tappet. This is caused by increased wear of the installed shim or camshaft cam.... If such a sound appears, it is necessary to adjust the valves as soon as possible, which will avoid big problems.
Much depends on engine oil quality , which has a significant effect on the degree of wear of the parts of the power unit.
The use of high-quality oil guarantees good lubricity of parts, which will significantly extend the life of the camshaft and other engine components.
In this case, the need to adjust the valves occurs when the mileage is 30-35 thousand kilometers, and it is quite possible that it will only be necessary to measure the values of the valve tappet clearances.
Why do you need to adjust the valve
The correct valve tappet clearance will ensure stable operation of the power package at full capacity. The valves are divided into two types:

Conclusion
Many owners of a VAZ-2115 car do not show due attention to the state of the valve tappet clearances, as a result of which they are exposed to increased wear of internal parts, which, at a minimum, will lead to costly cylinder head repairs.
Timely adjustment will allow the power unit to work correctly and extend its service life.
How to adjust the valve clearances VAZ-2114 8 valves
If on VAZ- 2114 1.5, in other words, 1.6 for eight valves “knocked” valves, this indicates that the components need to be adjusted faster. Often, not all motorists immediately begin to eliminate such a malfunction, which leads to more severe consequences. After all, if timely adjustment is not performed, then the engine power will significantly decrease, the valve will burn out, and the camshaft may generally be unbalanced. Do not understand how to correctly adjust the valve clearances on the VAZ-2114 8 valves? Then we advise you to study the information that will be further presented.

Without the help of others, adjusting the valves can be quite easy if you follow the annotations exactly and do the work in stages. Before, you should check the dimensions of the gap, when they do not correspond to the approved value, and a typical knock will be heard during the working engine, which means that the valves are absolutely necessary adjust... To accurately check the size of the gap, you need to wait until the motor has completely cooled down.
It should not be forgotten that if the measuring device is installed on a hot iron surface, then you will not be able to identify a clear size of the gap due to an error that is not excluded when the metal expands.

Inspecting and adjusting valves is an easy job that requires everyone to handle it if the annotations are followed closely:
- It is immediately necessary to remove the cover from the cylinder head.
- The protective front cover is removed from the toothed belt.
- The candles are unscrewed. For a more comfortable unscrewing of the candles, it is recommended to use an open-end wrench of the appropriate size.
- Excess auto oil is carefully removed from the upper part of the head.
- The integrity of the cams is painstakingly examined. If, upon inspection, any flaws are found on these elements, they must be removed without fail.
- On the studs, where the head is fixed, a special device is installed to help sink the pushers.
- Then you need to turn the crankshaft strictly clockwise until the mark on the back cover of the toothed belt and pulley coincides. After matching the mark, you must turn the crankshaft 50 degrees.
- Using a set of feelers, the clearance of the 1st outlet is checked. valve and the 3rd intake, the count should be carried out from the pulley.
- If the dimensions of the gap correspond to the indicators that were previously given, then the following is done:
- pushers are recessed and fixed at the highest or highest point;
- the washer for adjusting the gap is removed and its thickness is measured with a micrometer;
- Having decided on a suitable washer width, you need to take a suitable element from the kit and install it in the pusher. With all this, it is fundamental to look that the washer enters the pusher with the other side, it is occupied) its thickness is indicated;
- the gap dimensions are re-checked.
- Other valves are regulated according to the same scheme, here each time it is necessary to turn the crankshaft half a turn, and the sequence of adjustment should occur in this order:
- 2nd inlet and 5th outlet;
- 6th inlet and 8th outlet;
- 7th intake and 4th exhaust.
Countdown, as before, you need to start from the pulley.
After reading this article, there is an option to realize that without help others adjust valves on VAZ- 2114 easy enough. But if there is not the slightest desire to do this work without help others, then you will have to contact a service station. The adjustment price in a car service varies from 600 to 900 rubles. Experts advise to inspect the clearance and adjust the valves every 25-30 thousand mileage, even if, according to the driver's recommendations, the car is working normally.
Many motorists have encountered the process of adjusting the VAZ-2114 valves at a car service or carried out this operation with their own hands. But, not everyone knows after what period of time it is necessary to carry out this operation.
The video below will tell you about adjusting the valves on the VAZ-2114:

Valve clearance adjustment process
According to the regulatory and technical documentation and the practice of motorists, the valves must be adjusted every 15,000-20,000 km or when necessary.
Adjusting washer. With the help of it, the valve clearance is adjusted.
Special shims are used to adjust the valves. There are 125 sizes of them, but only a small number have found applicability.
Consider which ones: 3.30, 3.35, 3.40, 3.45, 3.50, 3.55, 3.60, 3.65, 3.70, 3.75, 3.80, 3.85, 3.90, 3.95, 4.00, 4.05, 4.10, 4.15, 4.20, 4.25, 4.30, 4.35, 4.40, 4.45, 4.50;
Consequences of untimely adjustment
It is known that the untimely carrying out of any operation for the repair and maintenance of a car entails certain consequences, which can be, in one case, mild, and in the other, fatal for the power unit. So, let's consider the main ones:
- Deterioration of parts and assemblies of the cylinder head, namely the gas distribution mechanism.
- Camshaft wear.
- Partial or complete destruction of pushers.
- In a separate case, it leads to a break in the timing belt and the corresponding consequences, such as. !
conclusions
The valve on the VAZ-2114 should be adjusted no later than after 20,000 km of run... Untimely adjustment work can lead to unexpected and destructive consequences. Therefore, the car enthusiast must follow the manufacturer's recommendations.
The valve adjustment procedure involves adjusting the clearance between the camshaft cam and the lateral face of the valve stem. Moreover, each manufacturer of a particular vehicle determines its required value, which is called the "thermal gap" and is designed to ensure that the valves are tightly closed at any temperature of the engine.
In this article, we will consider the "thermal gap" of valves on the VAZ 2114, or rather the technology of their adjustment.
Tools needed to adjust the valves.
- A set of shims.
- A set of probes for measuring valve clearances.
- Micrometer.
- Clamp for pusher springs.
- Specialist. tool: heads and keys 8-13 mm in size.
Adjustment instructions.
1. First of all, disassemble the air filter all the way down to the case.
2. Disconnect the pipes between the valve cover and the filter and the crankcase exhaust pipe.
3. Remove the valve cover of the cylinder head.
4. Remove the front timing belt cover, behind which is the camshaft gear, and on it the timing belt.
6. Then, for the mounting bolt of the alternator pulley, turn the crankshaft in the clockwise direction - so that the marks on the back cover of the toothed belt and the pulley coincide. And then a little more, about 3 teeth of the camshaft gear.
7. Using a set of feelers, check the clearances between the tappet of the first inlet and third outlet valves (counting from the drive pulley) and their ends. The first should be about 0.2 mm (+/- 0.05 mm, no more), the second - 0.35 (the error is the same).
8. In the case when the actual size of the gap does not coincide with the named values, it must be adjusted. To do this, drown the pusher, fix it in the lower position, and then remove the adjusting washer from there and replace it with a suitable one.
9. Further sequentially scrolling the crankshaft half a turn, alternately measure and, if necessary, adjust the clearances of the fifth exhaust and second exhaust, eighth exhaust and sixth exhaust, fourth exhaust and seventh exhaust valves.
10. At the end of the VAZ 2114 valve adjustment, install the removed parts in the required places in the reverse order.

What is the correct adjustment of thermal clearances in the gas distribution mechanism of a car or what does the adjustment of the valves affect? The main advantage is lower fuel consumption (which is important given the constantly growing price of gasoline). The engine runs quieter and smoother and accelerates faster.
How to determine and why valves are knocking. How often do you need to adjust the VAZ 2114, 2115 valves, what the manufacturers say. How are the valves located in cars VAZ 2114, 2115. How the clearances of VAZ 2114, 2115 are adjusted. Preparation of tools. Adjustment of valves.
How to determine and why valves are knocking.
If the valves are not adjusted, characteristic signs appear. The engine runs with a certain noise, a knock is heard on a cold VAZ 2115 engine, similar to a metal clatter. The reason for this is the gap between the levers and the camshaft cams.
This gap is set by the manufacturer, its value is the same for all motors of the same type. In this car system, an increase or decrease in the gap occurs, both of which have a bad effect on the operation of the engine and can lead to more serious damage.
Basically, this breakdown occurs due to the use of low-quality fuel. A good fuel is one with an octane number of at least 93.
Interesting fact! There is a fuel with an octane rating of 100, but it is only used in competition, fueling racing cars.
How often do you need to adjust the VAZ 2114, 2115 valves, what the manufacturers say.
Plants, car manufacturers, recommend checking the thermal clearances every 15-30 thousand kilometers. Even if, in your opinion, the engine works well, then such a procedure will never be superfluous, especially since you can do it yourself.
How are the valves located in VAZ 2114, 2115 cars.
VAZ 2114 cars are produced with an eight or sixteen valve engine.
Note! Adjustment of the valve clearance of the VAZ 2114 is carried out only for an 8-valve engine, since hydraulic compensators are installed on the 16 valve.
The valves in the gas distribution mechanism are designed so that when fuel is injected through one, exhaust gases are released through the other.
How to adjust the clearances of the VAZ 2114, 2115.
In order for the adjustment of the VAZ 2114 valves to be effective, the 8 valve injector must be performed on a cold engine. The size of the gap on the inlet valve should be 0.2 mm, and on the outlet - 0.35 mm.
Note! The permissible error in both cases is 0.05 mm.
Preparation of tools.
To adjust the VAZ 2115 valves, an 8 valve injector, we need the following tools: a set of wrenches for adjusting the VAZ valves, a device for valve tappet springs, dipsticks, vernier caliper or micrometer, adjusting washers.
Adjustment of valves.
Remove the cylinder head cover.
Remove the air filter and the front timing belt cover.
Unscrew the candles and fold them neatly. They are removed in order to make the crankshaft turn easier.
