The main function of the Valve Cover Gasket is to seal the gap between the valve cover and the engine cylinder head. During the operation of the engine, high-temperature and high-pressure gases will be generated inside. Without a good seal, these gases will leak, resulting in reduced engine performance, such as reduced power and increased fuel consumption. At the same time, it can also prevent the oil from leaking out of the valve cover, avoid oil contamination of the engine compartment, and ensure the normal operation of the lubrication system inside the engine.
