The valve cover gasket seals the valve cover to the top of the engine and prevents oil leaks, while the engine head gasket is located between the engine block and cylinder head, sealing the combustion chamber and preventing oil, coolant, and gases from mixing. The valve cover gasket is relatively easy to replace and often … Read more
Valve cover gaskets go bad due to prolonged exposure to engine heat, which can cause the gasket material to become brittle, crack, or shrink. Aging, engine vibrations, and improper installation also contribute to gasket failure. Over time, the gasket loses its ability to seal properly, leading to oil leaks and potential engine issues.
