remove the PCV and clean it out with carb cleaner/brake cleaner....shake it back and forth and make sure it is clicking....if not, replace it. It is on the top of the valve cover....

watch this....

if the PCV is not operating as mentioned, it may create pressure in the engine which may force oil out through weak gasket seals.

I feel for you guy, same thing happened to me. i would bet it is the pan gasket at the rear in the half circle it has to fit into the grove on the engine side. did you do like i posted previously to keep from getting the seal in wrong.
i ended up selling my jeep cause i could not get the leak stopped!!!

I'm just going to replace with a single piece gasket. I'm pretty sure that is now contributing to the issue.

ok! this is just to help others reading this forum: I found this video that shows the procedure...
https://www.youtube.com/watch?v=pyV3O34ttu0.

Now that I see this. I did two crucial mistakes during installation.
a) When I re installed the rear bearing cap, I applied RTV all over the joining surface. BIG MISTAKE. I must have changed the arc by adding distance and hence the leak.
b) The four piece gasket is a crap(well, four pieces of same crap). I will install one piece gasket and RTV ONLY (ONLY) at the corners.

I will order parts on my way to work tomorrow.

To check for a valve cover leak, just take a clean rag and wipe the back of the top of the engine, just below the top cover. Find oil and you have found a leak that imitates a rear main leak. (That top part the PCV goes into is the valve cover)

pay close attention how the gasket fits at the back of the pan in the half circle it must go into the grove on the engine side. i don't know how you will know for sure if it seats correctly since no visual. when i took mine apart twice it was all crimped over and did not seat??????? good luck......

A little goes a long way. This will keep your gasket from getting pushed out of place. Used to buy it by the case weekly at the Jeep Shop.

I placed order for all items @ PepBoyzzz.
1) Two PCV valves.
2) FEL-PRO One piece pan gasket.
3) FEL-PRO Valve gasket (this was the most expensive $36+)
4) New rear main seal
5) Oil filler cap
$88.57 total. Let's see if I can get this right this time around. At least it will not take me 2 days. I think I can get it done in a matter of hours. Also, I like the idea of Adhesive. I will buy that in the store (thanks Old4x!!!)

You only need one PCV valve to suck fumes out, the other hole is an elbow with a line to the air filter for fresh air in.

I'd add this to what old4x suggested...If you have the aluminum valve cover off already take the time to clean out the baffles. If they are clogged you'll get back pressure that will blow oil out of any weak gasket. I had just replaced my rear main, valve cover and oil pan gaskets. I had enough pressure that it was blowing out the new rear main, fuel pump and the distributor gaskets. Last weekend I cleaned out the baffles, replaced the gaskets on the fuel pump, distributer, reinstalled the valve cover and so far all is good!

Naw, what? Old jeeps are eminently renewable like a 60s VW Beetle. Other than rusted out frames they're just parts and even rusty frames can be fixed. Just my opinion
