maybe tomorrow, steady drip right from shaft area, I believe I need to get a harm bal repair sleeve because the crappy cranks wear out at the contact point, 127,000 miles, records show third engine maybe not....or all 3.8l have soft cranks....

never in my 25 years with jeep have i seen a 3.8 minivan motor wear the crank or balancer the 4.0 yes but the 3.8 was used in millions of minivans and wranglers there is a sleeve that must be used to prevent the spring in the seal from rolling out when installing the new seal, if you don't use it the seal will leak

I've found a few articles on the subject, and most importantly, I believe there is a repair sleeve on it already, which I believe is worn and needs to be replaced....

so do you still want assistance?

The new seal is screwing with me, now at idle no leak, as if it broke in,,,,, then when we rev the engine the leak starts again..?????
Expert:  bill replied 1 year ago.

if the balancer has a sleeve on it I would replace the balancer, and install a NEW OEM seal preferably using the guide tool to prevent damage

found this..
Expert:  bill replied 1 year ago.

looks like that crank is junk, what was the end play on it, while not common it is very possible the crank is moving around killing the seal, by the way the oil pump is inside that front cover and is driven by the crank

I pulled the sleeve off and used an install tool and installed a new seal. So far all looks good no leak. Theory, those that installed repair sleeve did not have simple install tool and could not get seal in without damaging seal.....

not a theory I have seen this that's why a timing cover comes without the seal installed now it is EASY to damage
