Leaking oil

I was changing the oil on my JK today (3.6) and noticed what looks like evidence of a minor oil leak but I can't figure out where it's coming from without tearing things apart (something I do not trust myself to do). I did snap a couple pics from below. I can't see anything from the top. Any ideas where it's coming from?

There is a "weak" spot where the head meets the block and front cover.
Could be that the gasket sticks out a little bit or not enough RTV during assembly.
Its difficult to see though it is right behind steering pump braket.
Good news is, there is no hight pressure oil galley in that corner just some splashes from the chain (s).

Hoping it's simple and not the oil cooler...

Not sure, but I'd get the timing chain cover checked. Had a leak like that on a 2015, and that was the culprit.

I degreased the motor, located the leak and started to inspect it regularely.
It was dripping a few drops a week and after switching to a thicker oil almost stopped.
To reseal the chain cover they have to remove a lot of parts: head covers, oil pan, everithing from the front - belt, pulleys etc. I know its covered by the warranty, I just dont think it worth it. I might spray some clear permatex sealer on that area one day though.

Covered by warranty? Go it it repaired! That's why you paid extra $ for one.
