If it's leaking at that PCV box, then definitely change the o-ring that seals to the valve cover. Also, have you checked the PCV and breather hoses for cracks or looseness?
That was 1994 or 1995. I had no problems with any vintage, have owned 1985, 1992, 1993.Later steel valve covers were redesigned as well for a better seal. No idea of the year that happened.
I don't have any problems sealing the stamped steel valve cover. But the two methods that work best are either cork gaskets for the long side, glued in place with Indian Head shellac, and rubber end pieces; or simply RTV on the long sides, and rubber end pieces. The Felpro Permadry plus gasket looks great, but those aluminum rails with rubber trim just don't seal as well they advertise.
- OH YES it is ,that old Style with Rubber Grommet !!!!!!! -pos for sure ----I use a cheap gasket, throw away the cork, use the rubber end pieces and RTV the long rails. I'll let it sit overnight and then torque the bolts just a little in the morning (like 1/8 or 1/4 turn). The trick is not to torque them too much when the RTV is wet or you squeeze it all out.
Also to OP, check that your front cam seal is not leaking and oozing out on the passenger side rear. I had that happen and thought it was the VC gasket since the smear of oil was in the corner around the VC seam and getting on the exhaust manifold (and smoking).
I never had good luck with that expensive 2.2/2.5 permadry single piece gasket and once they get hot, it is tough to get them off and re-use them. It is a good idea, but I never had good success with it.
I remember that PCV plastic arrangement. I think that can be eliminated with an emissions hose elbow. There should be a restrictor orifice inside the VC for that opening. EDIT: Is this the old style that has the rubber grommet?
-------------------------------------------------------------------------------------------------YES the old style with Funny Grommet ,what a stupid design from MOPAR, what where they thinking???? I called alocal Chrysler Dealer & they cannot get this part ,hmmm. I was thinking of finding Some Sort of Industrial Surplus gasket Grommet to go in place of that Distorted Old Grommet , By-the -way , John Wood Sir, the Hole in the valve cover on that 2.2 is NOT a perfect circle ,it has 4 - slots set in a cross hair pattern ,so the Sillly PCV breather Box/module ,gets Locked in Place when you twist it in Correctly.
