What is the effect of leaking valve chamber cover pad?
01 Affect the air tightness of the engine
Leakage of oil from valve chamber cover pad can cause damage to engine air tightness. When oil leakage occurs, the working pressure of the engine will leak from there, which will affect the stability of the engine. There is an exhaust gas recirculation valve connected to the throttle valve inside the engine, and air leakage will interfere with this system, thus affecting the working stability of the engine. In addition, oil leakage from the valve chamber cover pad can also be caused by aging of the valve chamber cover pad or blockage of the crankcase forced ventilation valve.
02 Affects engine heat dissipation
The leakage of valve cover pad has a bad effect on the heat dissipation function of engine. The oil leak will cause the engine to reduce the oil inside, which will affect the engine cooling effect. Especially in turbocharged engines, heat dissipation problems due to oil leaks can increase the risk of spontaneous combustion. Therefore, once the valve chamber cover pad is found to leak oil, it should be repaired in time to avoid engine damage and other safety hazards caused by poor heat dissipation.
03 Affect engine lubrication
An oil leak from the valve chamber cover pad will affect the lubrication of the engine. Specifically, leaking oil can result in inadequate lubrication of the valve chamber. If this lack of lubrication continues for a long time, it will cause wear and tear of the parts, and then damage the engine. Therefore, it is very important to solve the oil leakage problem of the valve chamber cover pad in time to ensure the normal lubrication of the engine and extend its service life.
04 The engine is badly damaged by oil shortage
Severe engine oil damage can lead to a variety of problems, one of which is the valve chamber cover pad oil leakage. This kind of oil leak not only causes the engine dirty, but also may start a fire. Leaking oil will combine with dust to form sludge, and when it encounters an open flame, it may ignite the engine, causing serious safety hazards. Therefore, once the valve chamber cover gasket is found to be leaking oil, it should be repaired or replaced immediately to avoid further damage to the engine.
05 Burning oil
Oil leakage from valve chamber cover pad may result in oil burning. When the valve chamber cover pad is leaking oil, the oil may enter the combustion chamber of the engine and burn with the mixed gas. This will not only reduce the efficiency of the engine, but may also cause engine damage. In addition, burning oil also increases fuel consumption and may produce harmful exhaust emissions. Therefore, once the valve chamber cover gasket is found to leak oil, it should be repaired in time to avoid further damage.
06 Rapid reduction of oil volume
A leak from the valve chamber cover pad can cause a rapid loss of oil. This is because an oil leak means that the oil is leaking from the inside of the engine to the outside, thus reducing the amount of oil inside the engine. When the amount of oil is insufficient, the lubrication and cooling effect of the engine will be reduced, which may lead to engine damage. Therefore, once the valve chamber cover gasket is found to leak oil, the gasket should be replaced as soon as possible to avoid further reduction in oil volume.
07 Swelling of wiring harness and hose
Leakage of valve chamber cover gasket may cause swelling of wiring harness and hose. This is because oil spills are usually accompanied by oil leaking around the engine, which can come into contact with wiring harnesses and hoses. The oil has lubricating and insulating effects, but too much oil can cause the harness and hose to swell. Swelling can affect the performance of wiring harnesses and hoses, and may even cause a short circuit or rupture, which can affect the normal operation of the vehicle. Therefore, the valve chamber cover gasket leakage is not only a mechanical problem, but also may involve problems with the electrical system.
08 cylinder pressure reduction and weak power
The leakage of valve chamber cover pad will cause the cylinder pressure to drop, which will weaken the vehicle power. The main function of the valve chamber cover pad is to seal the valve chamber and prevent oil leakage. When the gasket is leaking oil, the oil will enter the combustion chamber, resulting in a decrease in the compression ratio in the cylinder. Compression ratio is an important index to measure engine performance, when it is reduced, the engine combustion efficiency will also decline. Therefore, the dynamic performance of the vehicle will be affected, manifested by slow acceleration, difficulty climbing and other problems.
09 Stink in the engine compartment
An oil leak from the valve casing cover can cause a foul smell in the engine compartment. This is because oil leakage is usually accompanied by oil leakage, and oil is prone to produce bad odors in the high temperature environment of the engine. The smell not only affects the driving experience, it can also signal a mechanical problem in the vehicle. If this odor is found, it is recommended to check the engine as soon as possible to avoid more serious mechanical failure.
