changed rear main, bad oil leak???????

i changed my rear main today and at the same time i did an oil pan gasket, and now there is a pritty bad leak from the rear main, not quite as bad as it was befor i changed it. is it normal for it to leak some? if so how much? and how long does it leak for?

Sounds like the O-ring for the oil filter adapter is leaking. You can get it from Jeep, or at NAPA on the HELP! section "tree" (yes, I work for NAPA, but don' get a kickback for this) There is a multipack of the o-rings and it's the orange one.

Did you line up the two pieces with the cap? Did you use the right sealent on them? I think it takes the red locktite gasket maker. Lastly, are you sure it is not leaking out around the rear of the oil pan gasket that surrounds the rear main? I know this portion, and the front as well, can be a little tricky to seal up. That is where I would start.

Dollars to donuts the little spots that are supposed to get sealant didn't.

I had to do the rear main seal on our 90 XJ not long back. Not sure if it is the same as the 94 but I found that the two sections have to go it in a specific direction so the oil pressure causes the seal to "spread" when the pressure is against it. I used the one piece pan gasket and used red permatex where recommended. I found a lot of good information by searching the tech forum. I haven't had any leaks since but no amount of skill will beat dumb luck. Do a quick search and you'll find a lot of information about it.


HTH,

It took a few tries to get mine right. Make sure you add plenty of sealer where you're supposed to and let the whole thing sit overnight to cure.
Jeep on!

thanks for the help guys, i re did everything today, it took about 3 hours to do the job over again so i made shure to use plenty of rtv silicone on just about everything and there are no leaks, thanks again for the help

Make sure your CCV system is working properly, a clogged CCV will allow crankcase pressure to build and will blow that rear main seal in short order.
