Nope,..... My 1st guess is, yer over-tightenin' the bolts, or the valve cover is bent,....

They do make silicone rubber gaskets,.... donno 'bout the 3.0l though,...
I put 'em on a pair of I6s last year,... no more leaks,.... take-offs were probably original, 'n were cork,...

The use of sealer on a cork gasket is a bad idea.

An old mechanic's trick is to turn the cover over and knock the indentations (where the bolts go) back the other way.
