How did the Chevrolet Cruze valve cover leak?

The reason why the Chevrolet Cruze engine cover leaks is that the gasket is aging or damaged. The valve chamber in the engine structure refers to the cavity where the valve end is located. In the general automobile engine structure, the end of the valve is connected with the camshaft through the tappet or tappet, and the valve movement is controlled by the camshaft. The camshaft of modern engine is more placed on the cylinder head. The valve cover fracture phenomenon is as follows: 1. Damage to the valve cover will lead to oil leakage and affect the lubrication of the vehicle. Oil leakage from the valve cover will lead to insufficient lubrication of the valve cover, resulting in parts wear and tear, which will damage the engine for a long time. 2. The air leakage of the valve cover will affect the air tightness of the engine, and the working air pressure will also leak from the oil leakage. The engine has an exhaust gas recirculation valve connected to the throttle valve, which will affect the stability of the engine. 3. Leakage of valve cover will lead to dirty engine and even 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.
