High-quality repair of the cylinder head (cylinder head for short) is the key to coordinated and uninterrupted operation of the engine under any conditions. The future level of fuel consumption, engine thrust, its power and dynamics indicators will depend on how well the repair work was performed. In this article, we will consider how to make a high-quality repair of the cylinder head VAZ 2110-1113 with your own hands.
The process of removing parts from a car
Each spare part is pre-disassembled before repair. And repairing the cylinder head is no exception. So, the step-by-step process:
- Drain the anti-freeze (coolant) from the engine.
- We dismantle the carburetor, having previously disconnected all the wire hoses from it.
- Remove the air filter.
After dismantling all these parts, remove the head cover and combine all the marks on the crankshaft pulley with the mark that is located on the camshaft cover.
How is a cylinder head repair done?
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 down the drain. Therefore, if you are not confident in your abilities, entrust the work to professional masters. Below are the steps, following which you can make a quality repair:
- To begin with, all cracks that occurred during the operation of the cylinder head should be repaired. This must be done using argon welding. If, in addition to chips, the cylinder head is also deformed, then its design should be leveled using a milling or grinding machine.
- Next, replace the valve guide bushings.
- After that, change the valves and install new valve stem seals.
- If a malfunction of the pushers, rocker arm or camshaft has been detected, they must be completely replaced.
As you can see, this process consists of very serious work, so before starting and during this process, you should carefully monitor the sequence of your actions and not violate this algorithm.
Why is the head of the unit in need of repair?
The main reason why the cylinder head prematurely fails is the frequent overheating of the engine. In the summer, you can see more than once overheated "Lada" or "GAZelle" on the sidelines. And in order to prevent this from happening, it is recommended to install a radiator with a large number of sections and not squeeze all the power out of the engine. If the motor overheats several times, then the cylinder head is not only covered in chips and cracks, but also deformed. The latter type of breakdown is very difficult to eliminate by yourself, and the situation in the service station is no better - repairing the cylinder head will result in more than one thousand rubles. Therefore, take care of your car and try not to overheat it in the summer, and also not exceed the maximum permissible speed, otherwise a premature failure of the cylinder head will be inevitable.
