What is the effect of oil leakage from the valve cover gasket?

The effects of oil leakage from the valve cover gasket include vehicle lubrication, engine air tightness and engine fouling. The influence of oil leakage from the bonnet gasket is as follows: 1. Vehicle lubrication is affected, and the oil leakage from the valve cover will lead to insufficient lubrication of the valve chamber and wear engine parts for a long time; 2. The air tightness of the engine will be affected, and the working air pressure of the engine will also leak from the oil leakage. The engine has an exhaust gas recirculation valve connected to the throttle, which will affect the stability of the engine; 3. It will cause the engine to be dirty and even catch fire. The leaked oil will flow along the engine and combine with dust to form sludge. If you encounter an open flame, it will ignite the engine, which is very dangerous.
