Can a valve cover leak cause loss of power?
Most valve cover gaskets are made from plastic or cork and are used as a seal between the cylinder head and the valve cover itself. When this occurs, the gasket can lose its integrity and leak, potentially causing cosmetic issues like leaking oil, or drivability problems and reduced engine performance.
Why does my valve cover keep leaking?
Your valve cover gasket may be leaking for a variety of reasons. It could be shrunken, cracked or rotten, or your valve cover itself may be cracked or broken or one of the valve cover bolts may just be loose, allowing a little leak. Your car may have 1 or 2 valve covers depending on its configuration.
