Oil Leak between Engine and Transmission Question

Hi guys

I noticed a oil leak that stops when the jeep is OFF. but its dripping fast when its turned on.

I got under the jeep and i noticed that its leaking from like a cover that has a hole on it.. I bet underthere is the REar engine seal or something. here are some pics



I Cleaned it so theres no oil in the picture.
its leaking by that hole/gap there in the middle of that cover. What's that gap for? Its leaking from inside there.
I dont know if put some silicone there to hold a little until I get it fixed. I dont know the purpose of that hole. anybody knows?

also... i bought a BAR's LEAK Engine oil STOP LEAK.

WHy you experienced guys recomend? Should it work? Should I add it and see if it helps unti I can get to the problem?

I read somewere Bar's are one of the best. There are other junks that clogs stuff.

Please feed back.

I hope its not the real seal. Heard its very expensive and the trans or engine needs to be removed

It is probably the rear main seal and you don't have to remove the engine or trans to replace it. You have to drop the oil pan and the seal is in the bottom of the engine. I don't have a write up on hand but there are quite a few out there.

From the picture it looks like the oil pan seal. They don't cost too much. I changed mine a month ago and it was a pain in the ***. The oil pan wouldn't fit out because the exhaust pipe. I un-hooked the exhaust at the engine and it still wouldn't fit out. I had to drop the belly up to detach the exhaust under there. I know there has to be an easier way.

That's true for the 4.2 and the 4.0 but NOT the 2.5.
The 2.5 uses a 1 piece RMS which requires pulling the tranny to replace it.

What color is the fluid that's leaking?
Brown/black-ish or red-ish?


Red-ish would be you automatic transmission input shaft seal around the torque converter.

Brown/blackish could be your engines...
- rear main seal (RMS)
- the very back of your pan seal
- or your valve cover gasket. Oil can drip down the back of the engine and appear where you see it.

My 97 Sahara stars gushing out red fluid in between the engine and trans when I put in gear. What could that be?
