What is a car valve cover pad
automotive valve chamber cover pad , also known as valve chamber cover pad, is an important sealing part inside the engine. It is located on the valve chamber cover, and its main function is to prevent the gas and coolant in the combustion chamber from entering the crankcase and ensure the tightness of the engine inside. Valve chamber cover gasket is usually made of rubber, has good elasticity and wear resistance, can work in high temperature, high pressure and oil and gas corrosion environment .
The valve cover pad is subjected to great pressure and corrosion during engine operation, so it needs to be checked and replaced regularly to ensure the normal operation and performance of the engine. With the increase of use time, the valve chamber cover pad may appear aging, hardening, deformation and other problems, resulting in reduced sealing performance, affecting the normal operation of the engine. Therefore, the owner should check and replace the valve chamber cover pad as an important part of engine maintenance .
The material of the valve chamber cover pad also affects its service life. There are two main materials on the market: rubber and composite materials. Rubber valve cover pad is common, but it is easy to age. The composite valve chamber cover pad has better durability and wear resistance. The owner should choose the appropriate material according to the specific use of the vehicle and the manufacturer's recommendation to extend its service life .
The main function of the valve chamber cover pad (valve chamber cover pad) is to ensure the tightness of the valve chamber and prevent oil leakage . It is connected with the cylinder head and the valve mechanism cover on the top to ensure the smooth operation and full lubrication of the engine valve structure, while playing an important role in dust prevention and sealing .
Valve chamber cover pads are usually made of rubber and may harden with age after prolonged use, resulting in oil leakage. In addition, uneven screw pressure, excessive screw pressure, valve cover gasket deformation, crankcase forced ventilation valve blockage, sealing ring or sealant quality problems can lead to valve cover gasket oil .
The oil leaking out may be squeezed into the valve chamber cover, blocking the oil passage and affecting the normal operation of the engine. Long-term oil leakage will lead to the lack of oil lubrication in the internal parts of the engine, aggravate wear, and may lead to engine scrap in serious cases.
Therefore, when the valve chamber cover gasket is found to be leaking oil, the gasket should be replaced in time to solve the problem of oil leakage, ensure the normal operation of the engine and extend the service life .
