Valve Cover Gasket Sealing Issue
Thanks Rob
I've seen a few threads about valve covers not sealing or breaking ears off the corners of the BBM and the quality of the covers gets blamed. This is the real problem, the valve cover rails on the heads are never cast very flat and the covers snap when you tighten down the bolts because the cover doesn't flex.
I doubt your average engine shop can setup a head to machine the rails flat in a timely manner, so they don't even offer it. That's too bad, customers get REALLY excited when they learn they can use their expensive valve covers again and not have them leak.
