PCV valve?!!!!!!

I am assuming my 2005, 4.0 does not have a PCV valve.

Is this correct?

From MDM on another forum:

The 4.0L doesn't have a PCV valve.

It has CCV (Crankcase Ventilation) fittings. They are plastic fittings mounted through rubber grommets on top of the valve cover, one towards the rear and one towards the front. They serve the same basic purpose as the PCV valve but unlike the PCV valve they don't typically need replacing if that's your concern.

Best Always 🍀,
