Bellhousing leaking fluid
Hey guys just got my first jeep. 2002 tj x with 77k. I was walking out to my jeep this morning and noticed a little oil on the concrete. After further inspection I noticed the dribbles where coming from the bottom of the bell housing. What is the usual fix to get rid of this annoying leak?

Is it engine oil?

More than likely a leaking rear main seal. It's very common on the 4.0(mine's leaking)

It is dark like engine oil. How hard is this rear main seal to change?

A_Jeeper 08-23-2012 02:16 PM

I have never done a rear main so I can't say for sure. The transmission has to come out so it will be time consuming and difficult without a lift and proper tools.

Before concluding that its the RMS, check for an oil leak in the valve cover next to the firewall (easy fix). Seems to be pretty common and oil will drip down the motor past the RMS and onto the bell housing.

Ok will do, I just got underneath her and wiped all the residual oil.

This is a pic of what it looked like underneath. Before wiping her down.

Ok I'm starting to think it is the valve cover. After I wiped down the bellhousing and oil pan. I let it sit for about 30 mins and no residual oil. I popped the hood and the back of the valve cover does have some oil residue. I wanna degrease the engine and see what pops up. But before I do is there anything I should not get water on? I know to stay away from the electrical but is they anything else?

^ Why is that bolt loose?

goat347 08-23-2012 02:55 PM

The guy I bought it off of had the wrong bolt in I ordered a new one for it. Should be in shortly.

Ok stopped by a tranny shop and asks about the leak. And he's saying it is a cracked case most likely.

A cracked case?? I call BS!

What case is he refering to?

goat347 08-23-2012 05:18 PM

He saying that the tranny case is cracked.

bryantom 08-23-2012 05:21 PM

That oil thats on your picture doesn't look like tranny fluid to me. That looks brown, tranny fluid is a dark purple. Smell the oil, trany fluid and engine oil don't smell the same either. I'm with kfdjason on calling bs

kfdjason7620 08-23-2012 05:23 PM

If it was the tranny that was cracked then the spilled fluid would be red, IF you have an auto

kfdjason7620 08-23-2012 05:24 PM

Its either rms, valve cover gasket, or the oil pan gasket I'm betting

goat347 08-23-2012 05:47 PM

I have a manual transmission. I don't think it's the tranny leaking because I checked the oil level and it was full.

goat347 08-23-2012 05:51 PM

Hey quick question for the bellhousing bolts on my manual trans does anyone know the bottom center bolt size?
