I replaced my valve cover gaskets when I did my lim gaskets three months ago. I noticed that I have oil on my front exhaust manifold from a leaky valve cover gasket. I got the gaskets from zzp for 20.00 and also replaced the bolt grommets. I plan on replacing the gaskets again since there leaking but am wondering if I should go with a different gasket maker, I'm thinking of picking up the felpro kit for 50.00 from advance auto but am wondering if it's the same thing is get from zzp. Anybody else have a problem with the zzp valve cover gaskets?
