Repair of cylinder head on VAZ

The quality repair of the cylinder head (abbreviated to cylinder head) is the key to the smooth and uninterrupted operation of the engine under all conditions. On how well the repairs have been performed, the future level of fuel consumption, the engine's thrust, its power and dynamics will depend. In this article, we will look at how to repair the cylinder head of VAZ 2110-1113 with our own hands.

The process of removing parts from the car

Every spare part is preliminary disassembled before repair. And repairing the cylinder head is no exception. So, a phased process:

1. Merge antifreeze (coolant) from the engine.
2. We dismantle the carburetor, beforehand having disconnected from it all hoses of a wire.
3. Remove the air filter.

After dismantling all these parts, remove the head cover and align all marks on the crankshaft pulley with a mark that is located on the camshaft cover.

How do I repair the cylinder head?

VAZ-2112 and all other models of the "tenth" family are repaired in several stages, each of which requires certain skills and knowledge. And if you do something wrong, all the work will go to hell. Therefore, if you are not sure of your abilities, entrust the work to professional masters. Below you will find the stages, observing which you can make a qualitative repair:

1. To begin with, all the cracks that have arisen during the operation of the cylinder head must be repaired. This should be done with the help of argon welding. In the event that the cylinder head is deformed in addition to the chips, then its structure should be aligned with a milling or grinding machine.
2. Next, you need to replace the valve guide sleeves.
3. After that, change the valves and install new oil-removal caps.
4. If a malfunction of pushers, rocker arm or camshaft has been detected, it is necessary to completely replace them.

As you can see, this process consists of very serious works, so before and during this process, you should closely monitor the sequence of your actions and do not violate this algorithm.

Why is the head of the unit in need of repair?

The most important reason why the cylinder head prematurely fails is the frequent overheating of the engine. In summer, you can often meet overheated "Lada" or "GAZel" on the roadside. And in order for this not to happen, it is recommended to install a radiator with a large number of sections and not to squeeze out all the power from the engine. If the overheating of the motor happens several times, then in this case the cylinder head is not only covered in chips and cracks, but also deformed. The last kind of breakdowns is very difficult to eliminate yourself, and in the SRT situation is not better - the repair of the cylinder head will not result in one thousand rubles. Therefore, take care of your car and try not to overheat it in the summer, and also not to exceed the maximum permissible speed, otherwise the premature failure of the cylinder head will be inevitable.
