There is no pcv valve on the 4.0 engine. It is a CCV engine (crankcase ventilation).
If you are having issues with this system, I recommend you do the following:
1. Remove valve cover
2. Pry out both CCV grommets on valve cover
3. Clean valve cover thoroughly until you could eat out of it
4. Replace valve cover and valve cover gasket along with new CCV hoses (2)
You can buy the entire CCV kit for about $50 either aftermarket or from the dealer.
