I recently started DD'ing a '99 Wrangler (l4) with 150k miles on it, and after noticing some oil in the driveway I found out that the engine is leaking some oil (it drips quite a bit, but nothing too extensive). I brought the Jeep to a shop near by for a little inspection, and they said that it was a rear main. I noticed that once the Jeep was warm and running it seemed to a leak a bit more. I decided to take it back, and clean the oil pan to see for myself.

It doesn't seem to be coming from the end of the oil pan where it meets the transmission. I also checked the valve cover gasket and it was completely dry after the car had been running for quite some time. I noticed that it was coming from the oil pan, but couldn't necessarily pin point where even after I cleaned off the oil pan. I was thinking of replacing the oil pan gasket but wanted some input or advice before removing the pieces and grabbing the supplies and parts. Any insight would be greatly appreciated, thanks.

Clean the area off. Install some dye. Find the leak.
 
Easy thing to check... Are the oil pan bolts all tight? I've seen them loosen a bit and look like rear main leaks.


There must have been a time
when we could have said no.
