replacement of the cylinder head gasket

The cylinder head gasket is installed between the engine block and the base of the cylinder head. The gasket element is designed to seal the connections of the cooling channels and combustion chambers in the internal combustion engine. If the gasket is damaged, the engine loses the ability to operate normally, in particular, antifreeze mixes with oil, the cooling system becomes airy, and liquids penetrate into the cylinders.

 

When is the cylinder head gasket replaced?

 

A complete replacement of the cylinder head gasket is necessary in cases of damage to the element, which may occur due to engine overheating or improper operation. Due to serious boiling of the internal combustion engine, the plane of the head is deformed, which negatively affects the quality of the fit of the cylinder head to the block. Weak spots break and technical fluids mix with possible breakthrough of crankcase gases into the cooling system. Operation of the engine in this case is strictly prohibited, as it can lead to complete mechanical failure of all main components.

 

How the work process is carried out in the service

 

Replacement of a damaged gasket is carried out after diagnostics of the internal combustion engine. Experts determine the specific location of the fault. To replace the gasket element, it is mandatory to dismantle the cylinder head and part of the attachments. The following stages of repair can be distinguished:

 

Carrying out diagnostics
Dismantling of attachments
Replacing the gasket
Checking the integrity of the cylinder head
Installation of head and equipment
Replacing technical fluids
Repeated diagnosis

An oil change is only necessary when the fluid is mixed with antifreeze or has been seriously overheated. In case of significant damage, grinding of the cylinder head and lapping of the valves is required. After comprehensive work, the car will be able to operate in the same normal mode.

 

Correct selection and purchase of gaskets

 

You need to buy cylinder head gaskets in special stores where there is a wide selection of products. When purchasing, you should pay attention to the technical dimensions. One car model may have different cylinder diameters, so cylinder head gaskets are selected taking these parameters into account. High-quality sealing elements are distinguished by the presence of sealant and metal rings around the slots for the combustion chamber. If you do not have the skills to purchase spare parts, it is better to turn to specialists.
