HI,
I have a Mercedes 1993 300D and I recently replaced the valve cover gasket. I used what the Napa parts guy said was an original manufacturer from Germany. I haven't kept the box.
However, the gasket is leaking at the back of the engine where it has the wierd 1/2 circle of rubber. Is there a trick to installing it? Any tips to getting it to stop leaking? I installed it dry with not gasket sealer.
Thanks,
Mark
