Wow...don't know what to say except thanks!

OK...so here is what I have done....I have driven the jeep for a total of about 400 kms since I have had it....the bell housing hole has not been plugged (I just plugged it yesterday when I saw it so dust-dirt will not get in-but I have since removed it) and oil has never come out of it. I will keep that hole unplugged from now on!

OK...now to the PCV valve....I took off the round cover from the side valve cover and rotated it out towards the fender....then I unscrewed the ventilator control valve from the PCV valve...and was able to actuate and see the open/closed when using the lever.....great now I know that "level" is open and 90 degrees or vertical its closed...great...however, try as I could with two 12 inch wrenches, I could not crack open the PCV valve or disconnect it from its left side elbow for cleaning....even after 2 hours soaked in liquid wrench....so, I was not able to clean the PCV valve...back to square one in figuring out the oil loss.

Thanks Rob....you are a wonderful resource that's making it easier to maintain this jeep.

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!
