Is the ventilation valve chamber cover gasket overhauled?
The valve cover gasket is not an overhaul. The valve cover gasket is a vulnerable part of the vehicle. It will loosen or fall off due to aging and other reasons, resulting in valve oil leakage. Therefore, check the valve cover gasket on time. The engine valve cover mainly plays a sealing role to prevent oil leakage. The vehicle shall be inspected every 20000 km. If it is worn, it shall be replaced on time. If the valve cover gasket is damaged, it is easy to cause valve oil leakage, resulting in potential safety hazards. Among them, there are two main reasons for valve oil leakage: poor assembly process and aging of valve cover gasket. The assembly process is not good. If the valve has problems during assembly, it is easy to deform during extrusion, resulting in oil leakage. In this case, reassemble it, replace it with a new valve if necessary, and the valve cover pad is aging. When the vehicle is purchased for a long year or the driving mileage is too long, the aging of the valve cover pad is a normal phenomenon, In this case, only replace the valve cover gasket and sealing ring.
Relevant real cases
Q: After replacing the valve cover, how long can it be opened to determine that there is no oil leakage?
It is said that now the crankcase is forced ventilation. As long as the hot car does not leak oil, it proves that the sealing is OK. It has nothing to do with the length of time. I think the pressure inside the hot car engine will not increase with the length of time. In that case, it will be necessary to hold oil everywhere for a day?
Follow up: The spark plug was replaced two days ago. As a result, the worker removed the wrong screw and screwed down the screw in the middle of the valve cover. If it was wrong, he would rather have a screw. Is this OK? My valve cover is plastic. Also, I'm afraid of oil leakage. How many kilometers will it take to ensure that I'm ok if I don't leak oil?
Chase answer: It's OK. It's a common thing. If you don't see it, you won't care so much. The oil leakage is that the sealing ring or gasket is broken. You unscrew the screw. How can there be oil leakage.
Question: My valve cover is plastic. Won't it crack for me? At present, it has driven 1200 kilometers and no oil leakage has been found. Will it be all right.
Chase answer: You can rest assured that engineering plastics and ordinary plastics are too strong.
Question: Well, engineering plastics are stronger than ordinary plastics. Thank you.
