Should the valve cover gasket be replaced if the valve cover is leaking oil?
1 Answers
The valve cover gasket needs to be replaced if the valve cover is leaking oil. Here is a detailed introduction to the valve cover gasket: 1. Function: The valve cover gasket is primarily used to seal and prevent oil leakage. 2. Causes of leakage: Since the valve cover gasket is mostly made of rubber, it inevitably hardens and ages over time, leading to oil leakage. Oil seepage at the valve cover gasket may also be caused by uneven screw pressure, excessive screw pressure, deformation of the valve cover gasket, clogged crankcase ventilation valve, or poor-quality sealing adhesive. 3. Symptoms of leakage: The valve cover is located at the top of the engine, and the leaking oil flows down along the cylinder. The high operating temperature of the engine directly evaporates the oil on the cylinder block, producing a pungent odor.
