Archived oil leak

[clong6343]

I have a 96 2500 with a 12 valve in it and I am having trouble with the valve covers leaking . I put new felpro gaskets on and they still poured so I bought new valve covers and still pouring oil . Anyone ever seen this before ?

Did you defeat the design and put washers under the bolt heads? I've seen that before. Pushing the valve covers too far down splits the gaskets. If not, make sure the gaskets' surfaces on the head are clean.

Check the crankcase breather, could be building up pressure and letting loose at the covers.
