Well I guess it is back to the parts store for a new gasket set, What fun. The noise I am hearing is after the engine is shut down not while it is running. It sounds like metal contracting or maybe a valve spring uncompressing. Maybe I will buy a new valve cover gasket set also and pull them off to take a look. It seems as if I will never get to injoy driving around on a beutifull spring day. well thanks for the advice so far.
