Question about 2006 Jeep Cj
How to install 2 rubber rear main seals in a M38A1 Jeep engine without damage.
Actually yeah you are in luck that combination only requires dropping the oil pan. The seal is actually fairly easy to do it yourself, if your inclined. Parts about $20.00 and it's book rate is 5 hours. around here shops charge around $85/hour. About $500.00 out the door or under $50.00 if you want to get greasy. Here's a good picture guided step by step on a Jeep CJ with a 4.0 liter, yours is pretty much the same:

Wrong. just remove the oil pan, exhaust downpipe and O2 sensor, and starter. take off the crank bearing brace and finally remove the rear main bearing cap. half the seal will be in the cap and half you push out from around the crank with a small brass punch so as not to damage the crank pull out with needle nose pliers and slide the new one in ( noting that oil should go on the mating surface of the crank and liquid dish soap on the outside of the upper seal). rtv the lower seals wings (top and bottom) and reinstall. rear main cap 80ft.lbs i believe, 35ft.lbs for the bearing brace. or just follow this tutorial with pics http://dailydriventj.com/forum/viewtopic.php?t=811

SOURCE: Rear engine oil leak....
Oil leak can be attributed to several factors.
1. Gasket failure.
2. Uncontrolled Crank case pressure Failure.
Tighten both the valve cover and oil pan bolts.
Replace the Positive Crankcase Ventilation Valve and vacuum line.,
This is a valve causes a negative vacuum on the engine while its running, As to say if it had a leak in a valve cover it should not be leaking while its running, only when the engine it turned off.
Hope this tip guides you in the correct direction to solve this problem.
