MY jeep started leaking oil out of the back of the valve cover I have a 2.5 L it only leaks after driving of its sitting it doesn't leak any oil. I've replaced the valve cover gasket being careful not to over tighten it but I'm not sure if it was already messed up. Any one have any other ideas? Someone mentioned PVC valve but not sure how to check that.

It took me 2-3 tries to get my 2.5L valve cover to finally seal. What I finally did was pull the valve cover off (again), pulled the rubber gasket off in one piece (looked to be a good shape still). Degreased the valve cover and cleaned it.

Then I put a ~1/8" bead of high temp oil resistant RTV around the gasket surface valve cover, then I carefully set the rubber gasket on the RTV and let it sit over night to cure.

The next morning I put the valve cover on and torqued the bolts...no more leaks.
