Bad Valve Cover??

I have resealed these covers over and over and over and.......... The valve covers are made from an extremely fibrous plastic. They warp, and sometimes they even crack, though the cracks are incredibly hard to see. (They only show up under torque) After having to warranty gaskets many times, my shop now ONLY replaces the covers. They are good for about 60-80K miles after replacement. It isn't that uncommon to have to replace the covers. If you bought all of the gaskets, including the isolator bushings on each bolt, it is only about $100 more to replace the whole cover.

The replacement cover comes with all brand new, upgraded seals, gaskets, and isolator bushings, and bolts. The one bolt that is not included, is the one at the top left corner of the valve cover. (The only one that can be removed from the isolator.) It is worth the replacement, the new gaskets are much stiffer than the regular replacements, and last much longer.

A good cleaning and a dab of RTV on the back side solved the problem
