Yes. The PCV of the 4.0L SOHC is in the back face of the driver side valve cover. You can ID it by the small horsehoe coolant tube clipped onto it. Removal is much more difficult that in earlier years (Don't blame Ford - it is mandated by the EPA to lock in place to discourage it from becoming accidentally unplugged).
My 2003 shop manual gives a completely vague non-description of the PCV valve replacement. Right or wrong, here's what I did:
Wait for engine to cool.
Pull the large PCV elbow off the PCV valve
Clamp off the two small coolant hoses that lead to the horseshoe tube. I used two needle-nosed Vise Grips.
Squeeze and slide the constant tension clamps up the hoses.
Remove the hoses from the horseshoe tube.
Turn the PCV valve 1/3 turn CCW to release it.
Reassemble in reverse order.
