Degrease it and then run it. Fresh leaks will show up fast.

Here's all you need to know:




I'd be looking up ABOVE first, and VERIFYING the source of the oil leak YOURSELF.

Everybody, who doesn't own or have to pay for or perform your vehicle repairs, loves to poke their noggin UNDER the Jeep and come out bearing the false bad news that your RMS is leaking.

Many mechanics, friends, people on Jeep forums who can’t see your Jeep from where they’re at, and good old Uncle Bob seem to enjoy telling you it’s the rear main seal. Has a catastrophic ring to it, doesn’t it?

A simple leak at the back of the valve cover or other source could produce the same symptoms. You don’t need to be a mechanic to figure this out. If you have good eyesight and a dim flashlight, you’re good to go on your own. Don't jump on the RMS/oil pan gasket bandwagon right off the bat.

Almost any oil leak on your 4.0 is gonna drip from the RMS area for two simple reasons.

First off, the engine sits nose-up and any oil will run back to the RMS area. Secondly, the RMS area is also the lowest point on the engine. Simple physics and the old plumber's adage apply here. "***** flows downhill".

Valve cover gasket, oil pressure sending unit, oil filter adapter seals and distributor gasket, in that order, have to be eliminated as possibilities first.

Degrease with cleaner. Take one bottle of baby powder douse the side of the motor. Look for brown powder after running. There is your leak.... easy plus it makes it smell baby fresh...
Why does everybody make finding a leak so tough?

If its stock it sucks and if it scares the hell outta ya its just about right!

You got me. That's why I posted the write-up above. So many leaks are misdiagnosed by people with half-assed answers, it makes you wanna puke.

Lol. Novel concept! A lot like when engineers would come out to the track. Huh so that's why that design sucks.... you could talk until blue but a live "catastrophic failure of containment" was priceless!

Yep. And a systematic method of diagnosis would have been easier and cheaper. all is not lost though as the other gaskets/seals are now new.
