If there was any smoke coming from the exhaust than that wouldn't be a valve cover leak, right? What you are desribing woud lead me to believe it's the valve seals. I was always told blue smoke was from a head gasket gone bad (coolant). Been there with two of my Buicks blowing the gaskets. I could be wrong though. I guess I am confused. I hope it would be a valve cover gasket and not the valve seals or any other seal for that matter (rear main would suck)! I am just scared to take it in for warranty work and find out my warranty (not factory) won't cover it. I s a repuatable(sp?) company too. I think its time to trade it in.![]()
