|freakengine||I'm frequently amazed by how much good info there is on this forum. I have a similar leak on my 98 TJ and this gives me a lot of leads to follow. Thanks to the OP and all the other posters.|

|n00g7||I have a drip (new) from the bell housing that appeared after I minorly crushed my oil pan. Waiting to see if it stops b4 next oil change prior to doing anything (might just be a little full and leak from somewhere as I need to lower oil capacity until I bang out the pan). Oil pan itself is dry. Does that eliminate any of the above, out of curiosity? I'm really thinking it tweaked the pan and its seal, but it seems odd to me that it would leak back to the bellhousing only.|

|Neil F.||You can add UV dye to the system. Just about any shop can do it or you can buy a kit. When you hit it with the black light it is very clear where it is coming from.|

the jeep leaks from these places:
1. Rear main seal
2. Valve cover gasket
3. Oil pan gasket
4. Head gasket
5. Oil pressure sensor shindig.
6. timing case cover.
reach behind your valve cover and see if its oily. yes? change tighten valve cover bolts. check a week later. Still oily? change valve cover gasket.
Is the bell housing on your transmission oily? does it look like its leaking from where the oil pan and the tranny meet? Tighten up the oil pan bolts in that area. only a little though, you can strip them.
Wait a week. oil gone? if not, change oil pan gasket and RMS.
There are a few write ups on the RMS seal changes. If you or anyone has any questions about it, ask me.

|Nich||In had the same leak and it turned out to be the valve cover on the drivers side by the firewall. I didn't wipe my clean to check and all that I just looked and it was pretty oily n wet. There is a great write on hear on how to change. Pretty simple just be careful with the old plastic hoses like the crank breather tube that goes into intake. Mine crumbled when I touched it. Hope for u it's valve cover n not rear main. Cheaper easier fix mines been good for a couple months now. Good luck bro|

This. Check the valve cover by running a rag around it to clean things up. Run it for a bit and then run the rag again around the edge again to see if you're getting any leaks.
If it's not that, could also be the pan where it meets the block and RMS is the other.

|Water Dog||Could also be a valve cover leak running down the back. You might want to check that before tearing the bottom apart.|

Oil leak and i have no idea where its coming from
Hey guys, do recently my Jeep has been leaking oil, from where I have no idea what it's called but the drain plug and pan is wet with oil and I assume the areas between the tranny and engine. What could it be? I have an 02 4.0 with th NV 3550 thanks y'all! Here are some pictures of the leak
