Hello, my name is***** you replaced the valve cover gasket did you also replace the small square gasket that goes around spark plug chamber?
Rectangle gasket, not square. Sorry about that.
Here is a picture so you can see the rectangle gasket I'm referring to. Thanks.
I did see the picture and see the hole. If problem just started out of no where then I doubt the hole is the problem. I'd personally put silicone in the hole to see if that helps if not replace the valve cover gaskets again. If problem still exists then use a straight edge to check valve cover for being warped. I'll also open question back up to see if someone else can give you a definite answer on the hole. I just wanted to make sure the small gasket was replaced. Thanks.
