What Is The Cause Of Oil Leakage In The Engine Cylinder Head?

2021-09-17

Reasons for oil leakage of automobile engines: First of all, most of the engine oil leakage is caused by the aging or damage of the seals. The seal will gradually harden over time and continue to alternate between cold and heat, lose its elasticity (professional name is plasticization), and may break seriously. This caused oil leakage. From the top, middle, and bottom of the engine, aging seals are common. A more important seal on the top of the engine is the valve cover gasket.
 

 
Valve chamber cover gasket: This should be the most common. You can see from the name that it is usually installed on the valve chamber cover. Due to the large sealing area, it is easy to cause oil leakage after aging over time. Correspondingly, most cars have a long life. Of car owners have encountered it. The gasket needs to be replaced. The main hazards of automobile engine oil leakage: loss of oil, resulting in waste, and severely may lead to insufficient oil and lead to engine damage. It is not caused by the oil leak, but because the oil pressure is insufficient after the leak, so just pay close attention to the oil level.


1. Engine oil leakage caused by inadequate sealing such as valve cover gasket, oil radiator, oil filter, distributor housing mounting hole, rocker cover, cam bearing rear cover, and deformation of the engine bracket plate situation.
2. When the front and rear oil seals of the crankshaft of the automobile and the oil pan liner are damaged to a certain degree to a certain extent, it will also cause the engine to leak.
3. If the timing gear cover gasket of the automobile is not operated properly during installation, or it is damaged to a certain extent, the screws produced are loosened and the oil leaks.

Treatment and hazards of engine oil leakage:
1. The solutions adopted for different models are also different. Some engine oil leaks do not require removal of the cylinder block, but some parts of the leaking cylinder block need to be removed. It is best to deal with it according to the specific situation of the car.
2. The oil leakage of the car's engine is not a major fault, and we may not need to repair the car for the time being. But if the engine is leaking oil, it needs to be carefully tested.
3. Oil leakage from a car's engine will cause certain injuries, the most important of which is the loss of a large amount of engine oil to the car, and there is a waste of it. If it is serious, the engine may be damaged due to insufficient oil.
