Although the valve cover gasket is just a small sealing gasket, once there is oil leakage, there are still great safety hazards. So what are the hazards of the valve cover gasket?

1. The oil pressure of the valve cover gasket is reduced due to oil leakage
Due to the oil leakage of the valve chamber cover gasket, the oil level is directly reduced, and the oil pressure is too low, and the lubrication is not in place during the engine operation, which will accelerate the wear of various engine parts and reduce the service life of the engine.

2. Oil leakage of valve cover gasket corrodes peripheral parts of the engine
The oil leaked from the valve cover flows downwards, and adheres to some peripheral parts of the engine, which will corrode these parts, such as the engine wiring harness. If the periphery of the engine wiring harness is corroded and peeled off, it may directly cause many sensors or actuators to work badly and affect the normal operation of the engine.

3. The oil leakage of the valve cover gasket has potential safety hazards such as fire
First of all, the oil leakage of the valve cover gasket has potential safety hazards such as engine fire. As the valve cover gasket leaks, the leaked oil will flow down the engine body. As the temperature of the engine body is very high when the engine is working, the oil adhering to the surface of the engine body will slowly evaporate and produce a pungent odor. It will enter the compartment along with the air conditioning system and affect the compartment environment.

Secondly, when the oil leaking from the valve cover adheres to the exhaust manifold of the engine, the hazard at this time is not just the pungent smell. When the vehicle is driving at high speed in the hot summer, due to the exhaust The temperature is very high, causing the oil adhering to the exhaust manifold to burn, ignite other combustible parts, and cause a fire in the engine compartment.
