Introduction
Valve cover gasket is generally made of a sealing material, usually nitrile rubber or silicone. This sealing material is widely used in automobile engines because of its heat resistance, good elasticity and sealing properties. The valve cover gasket covers a large area and must take into account both sealing and durability.
When lubricant from one pipe flows to another pipe, it is retained at the valve cover by the valve or valve spring. In this way, the various instruments and mechanical parts of the car engine can fully obtain the lubricating oil required for operation, thus ensuring the normal operation of the engine. Therefore, if the valve cover gasket leaks, it will have a serious impact on the normal operation of the engine.
