Oil coming from under oil fill cap
Got a 2002 4.0L that runs great, just one issue: it pushes a very small amount of oil out from under the oil fill cap on the valve cover. Not much, every 300 miles or so I have to blot up a small amount. I checked the cap, it seems fine, secured tight. There is no gasket on the cap, not sure if there is suppose to be. If the cap is fine, could the PCV/CCV valve be the reason why oil is coming out of the cap?
