Review on High-Quality Donepart Valve Cover Gasket VS50504R1 with Grommets for 1997-2016 Chevy Cadillac Pontiac GMC Buick Avanti Hummer Isuzu Saab – Perfect Valve Gasket Cover Set! by Andre Noel

My truck has never had a rocker cover gasket leak, but I ordered these gaskets to be proactive on other repairs. Unfortunately they don't seal very well because they are now leaking at the back of the engine. This is not the first time I have replaced valve cover gaskets on an LS engine and I cleaned the gasket surface very carefully and installed the replacement.
