Porsche Cayenne S Sport Utility 955 4.5L V8 Gasket for Spark Plug Holes in Valve Cover

Replace these along with the valve cover gaskets. I had oil leaking into the spark plug wells and a burning oil smell from the engine after driving. After replacing all gaskets under the valve covers, both issues were gone. This is not an easy job on Cayennes. Be prepared, and set aside a couple of days to do it.
