Oil Leak Help

I have a little oil leak going on, its dripping inbetween the bell housing and the cover, I'm not expert yet, but does anyone have any idea what it might be or where to start? I can get a picture here in a bit if you need it.

Probably the rear main seal, fairly common problem. It could be leaking from higher up. Clean things off well and watch it. Check the valve cover. Folks sometimes spill oil on the side of the block when changing the filter. If it isn't cleaned off, it will run back and then down looking like the rear main is leaking.

Keep in mind that free advice can frequently be worth less than you pay for it.

well, if its the rear main seal, wouldn't it be dripping alot when the Jeep is running? And when i feel around the back of the motor, my hand is covered in oil, I think it might be a head gasket. How hard is it to replace a rear main seal? Im a DIY guy. I just did the headers.

Make sure its not running down from the valve cover, or running down the side of the oil pan from the oil filter adapter. It could still be a rear main or oil pan gasket too. I highly doubt you have a head gasket leaking oil. A bright flash light a small inspection mirror might help, after you clean the area with brake clean to try find a leak.

I dont know you mech ability but rear main seals are not too bad to do, along with all the other problem areas I mentioned above. I would at least try to eliminate the easier things first before suspecting the rear main. There are a few good write-ups on all these oil leaks on this forum so search for those before you try to fix yours.

I had similar problem. Mine was oil filter adapter. Still cant get the damn thing off. The t60 bolt is on there!! Lots of good advice here though, like degrease and really watch for it man. Its tough to pin point oil leaks sometimes.

My standard response:

A RMS done with the engine in the vehicle is not fun but doable. Fact of the matter is that many owners have their Jeep's oil leaks diagnosed by someone else who proclaims the RMS is leaking when it isn't.

Since our engines sit "nose-up" in the engine bay, any oil leak up above is gonna drip from the RMS area. Therefore the misdiagnoses.

You don't have to be a certified technician to diagnose the oil leak on your Jeep.

Start by looking at the valve cover, especially around the back side. Move on down to the oil pressure sending unit mounted above the oil filter. From there, inspect the oil filter adapter housing that the oil filter is screwed on to.

Repair them from top to bottom and you may find that the "RMS leak" is gone.

The only thing that kinda makes me think twice is that it isn't leaking bad at all, but the leaking is coming from in between the bell housing and the thin metal plate that goes on the front of it.
