What are the hidden dangers of replacing valve cover with aluminum alloy?
There is no security risk. Replacing the aluminum alloy valve cover can indeed achieve a better sealing effect, but it is also necessary to check whether the rubber gasket is aging and damaged during installation. If the gasket is not replaced due to aging, even if the aluminum alloy valve cover is replaced, the problem cannot be completely solved.

There is no safety hazard when the valve cover is replaced by aluminum alloy. In fact, the reason why the owner wants to replace the aluminum alloy valve cover is because the gap in the valve cover is really too easy to leak oil. In fact, replacing the aluminum alloy valve cover can really play a better sealing effect, but when installing, you should also check whether the rubber gasket is aging and damaged. If the gasket is not replaced due to aging, even if the aluminum alloy valve cover is replaced, the problem cannot be completely solved. Secondly, we can also choose some oil that can soften the gasket, which can increase the sealing performance of the valve cover.

Never glue when replacing the valve cover? There is no such thing. If the oil leakage problem of your car can be solved after replacing the gasket, there is no need to glue it at all. If the problem of oil leakage still occurs repeatedly after replacing the gasket, then we can choose to glue to improve the sealing performance of the valve cover, and we can replace the valve cover together if necessary. It's just that it will be more troublesome to replace the valve cover next time after gluing, and it needs to be cleaned before replacement, and the maintenance cost may rise.

What is the function of the valve cover? The main function of the valve cover is to protect the camshaft of the engine, and at the same time form an approximately closed cavity with an oil return circuit and an oil supply circuit connected with the cavity. The valve cover can effectively prevent dust from polluting engine oil or dust from entering and accelerate the wear of valve train parts. Therefore, we usually need to check the sealing condition of the valve cover and deal with the oil leakage in time to ensure the durability of the engine.
