Leak?

I'm probably using the wrong term. I'm talking about the valve head cover where your PCV valves are on top of your engine. If I'm saying it wrong by referring to it as a head gasket, sorry! Like this one

Yes, you are using the wrong term. A head gasket is a totally different thing. You are referencing a valve cover gasket.
That's the valve cover (sheet metal material), which is bolted down to the head (cast iron piece that the spark plugs are mounted to). A valve cover gasket is a DYI job for someone even remotely mechanically inclined. A head gasket replacement, which is the gasket sandwiched between the head and the engine block, is far more involved. Totally doable, but lots more involved (technical) and lots more work.

Looks like a rear main seal to me, I just had a shop do it for around $450, (1 year warranty) that's with a new oil pan...looks like you could use one. I also purchased the 9th degree skid plate for my oil pan, all my damage was done by previous owner when the jeep was stock height. It has a 3 " lift and 1.25 body lift now for a little more clearance.
Having just done this repair on an 04, both the video that @JMT posted and the How-To guide so a slightly different RMS than what I found. The difference is in the lower half of the seal. There are two "legs" if you will on the lower seal on EVERY guide I've seen. When I opened mine up, the legs are no longer present. The upper and lower seal halves are identical. Unfortunately, I didn't take any pictures, but here is a pic of the seal from Amazon...I'll update the "how-to" as well.

A few months ago I asked @Chris if he could update his RMS Replacement How-To Guide for that reason since I ran into the same problem ... he did.
RMS leak is one of those things that will happen lol mine leaked while it was still under warranty. Leaked some time after that again and I replaced it myself. maybe about 4 years ago it started leaking again. Not worrying about it until the leak gets to be too much lol.
I should make a sticker that says something like this
"RMS Leak ... It's a Jeep Thing You Wouldn't Understand"
IMO unless you are losing so much oil that you can read the word "add" (between oil changes that is) you don't need to change it. I have no place to change mine and do not want to pay someone so if mine were to start leaking I wouldn't replace my RMS until it was leaking too much. It's not hard but would prefer to lift it off the ground to do it. I live in an apartment so I am kind of stuck at the moment.
Make sure your valve cover isn't also leaking. That could mimic a RMS leak. Mine has been leaking ever so slowly for years.

I'm going to change mine here in the next couple of weeks, hopefully that takes care of my leak, if not RMS change time
