My Jeeps bleeding!

I'm 90% sure it's coming from the rear main. I have seen oil dripping from the front of my trans. And.from the back of my oil pan for some time but it seems to be getting worse. I'm keeping a close eye on my oil level and it did go down a little. It is a I6 with a 5 speed... How much should I expect to pay to get something like this fixed and how much time can I let go by before it's too late?

The rear main oil seal leak is a common problem. I have a small leak in the rear main seal that leaks maybe 1-2 drops a day. I have one of those Jeep maintnence books and after reading through the instructions on getting to the rear main seal, doesnt seem like a very tough task. As for how big of a problem it is, as long as its not gushing out oil it should be fine. Just make sure to check the oil levels every so often.

Just helped my son do his, and it's really not a bad job. Worst part is all the bolts to remove the pan. The seal itself is pretty easy. I would guess that a garage would get a pretty good price for it...just because they can. You should be able to do it yourself in less than 4 hours.

I did mine a month ago. Ok, learning curve aside, i'm pretty sure i did everything right. HOWEVER, now i went from a few drips to "hey man, you're leaking oil". Haven't driven since, but before i pay a mechanic to do it "right", I think I read on some writeup it takes a while for the seal to "swell up and seal". Was this the case with yours - or dry after replacement??

Before you get too deep in to it, make sure your valve cover is torqued down. I once had that issue and upon closer inspection noticed that it was actually my valve cover gasket. I began prepping to remove the cover and change the gasket when I discovered that the bolts holding it on the head were finger loose!

I though my rms was leaking until I reached behind my valve cover and notice oil was seeping down the back of the engine.
Changed the valve cover gasket and no more oil leak.
