Update!
Finally got the PCV valve off from the left elbow (over the fuel pump)by using heat. Then used heat again to unscrew the PCV valve....very clean...just light sooty deposits...cleaned and replaced so not sure if this is the culprit for the oil loss.
Still trying to figure out where the oil is going. I have not driven the jeep for 2 days due to bad weather so I looked underneath and nothing was leaking at all. After a drive, a drip or two comes out of the rear main seal, seal between the engine & transmission and lesser weeping form one differential....that's it!
