My valve covers are original pieces and they look ok. But on the passenger side I keep getting an annoying drip right ontop of the manifold. I've changed it once and it still leaks but not in that area anymore. I used the extra gasket I had in my engine gasket kit from Fel-Pro KS2110 I think. They are the rubber coated fiber gaskets. The one that I took off was already brittle and I haven't even driven it yet, still doing adjustments. The other side doesn't leak. What's the best 400 valve cover gasket you can get to insure a leak free valve cover? I considered the Mopar performance black wrinkle valve covers but I want to run my oil cap and breather element on the passenger side and the PCV on the other side. I believe the Mopar valve covers only have one hole each side. Does anyone make new valve covers with the holes for the OEM breather, oil cap, and pcv?
