If there isn't enough gasket compression, any gasket will leak. If the valve cover is distorted no gasket is going to seal.
My prior posts in this thread outline how to identify and solve the problem.

I found some pictures in other threads (
Cam cover leak repair and
Valve Cover Modifications for OM617 ). I hope they help!
My genuine Mercedes (Bruss, made in Ireland) valve cover gasket is leaking, but I might have installed it 8 years and many miles ago, and it's been in an extreme hot and dry desert environment. I noticed when it was new, that it had a cratered sealing surface (bad casting, worn mold?) that didn't seem like it would seal well. But, it worked for several years.
Now I have a new genuine Mercedes Bruss gasket, and it looks even worse. I wonder if it will seal at all.
