The rear main seals are known to leak with age. Not two within 4500 miles.

Not to sound like I'm accusing, but was it the same mechanic who fixed it the first time? Makes you wonder if whoever fixed it the first time tightened it enough then... I'm not the world's greatest mechanic but when I had to get the tie rods fixed on my 92 Dogde colt a few years back and the mechanic told me the boot got wrecked cus it had fishing line wrapped around it, I said ok, it's under warranty anyway, fix it. 6 months later I brought it back to him for similar noises, he told me the OTHER side had a tie rod problem cus the boot got wrecked when fishing line got wrapped around it. Apparently he didn't remember telling me that the first time... I told him that since he didn't notice it when he examined it 6 months before trying to find the same noise problem I was taking it elsewhere... long story short it was a lube problem that was causing wear and cost little to fix when someone else examined it... never went to that guy again and it's a shame, before that he had always treated me right, still not sure what changed...

Its always been my understanding that the I6 rear main seals have been an ongoing instalation issue for years. Dealers even screw them up when fixing under warentee, so Im guessing some sort of design flaw between the block, pan and the seal inself.

These engines are produced by the tens of thousands years before they get installed by DC at the factory. So the problem excists way in advance of production and even when DC knows about the issue prior to the build date, they leave it for the end user to find and thier dealer to repair. Rather than fix before build. Its cheaper for them due to the large amount of owners that either ignore the problem or never look under and see whats going on.

My 99 Ram w/5.9lt V8 had a blown intake seal right off the lot. This was a common problem.....another that DC wouldnt admit was a problem btw Rolling Eyes sort of like the auto tranny problems that they wouldnt admit were a problem.......But the symptom was extremly poor fuel mileage. As the engine sucked air past the seal they EPU would see a lean condition and pump more fuel to the engine, hence the excess fuel use. I got 5 more MPG after the repair was made under warrentee.....again many owners just ignored the problem and it didnt cost DC any money to fix.

I use to own a 90' Cherokee with a I6 and had rearmain seal problems. I did the dealer thing twice, but it still leaked. I wound up doing it myself and had no leaks afterwards. I checked for nicks, gouges and other flaws that might cause the leak, but found nothing.
But let me tell you, it was a BIG pain in the ass to do.

ok several things.

when they said they were going to "tighten the bolts", how long did that take them. to get to those bolts you have to drop the oil pan, and just re-tightening won't fix it anyways.

secondly there is a bulletin about the rear main on the TJ's leaking. there is a hole right at the very top of the tranny to engine. dirt gets in there and ends up clocking/grinding at the seal causing it to leak sooner. the vehicle is to be inspected and the rear main replaced if required. after that the hole is to be sealed with RTV to prevent future contamination.

but other than that rear main seals are relatively common. all 3 of my jeeps were leaking from the rear main but they all had between 80,000 and 176,000 miles on them.

they had the car for about 6 hours, they said they tightened the bolts and ran the jeep for an hour and did not notice any more leaking.....went on a 4 hour ride and it is leaking.... the service manager said that this is suppose to happen to keep the bottom of the seal lubricated....he wanted to show me a 2006 tj doing the same thing . so i would drop it... i paid 24000 for this 7 months ago. i will be more than happy to get my money back if jeep is that incompetent....will keep ya informed....gonna take back to dealer in 2 weeks.

it's supposed to leak to keep the bottom of the seal lubricated??? boy then i must be in alot of trouble. because i just resealed my entire engine, and i don't have ANY oil leaking anywhere at all. i guess my seal must not be getting lubricated now???????????

i really hope you told him he needs to quit eating so much shit for lunch cuz he's already full of it.

a brand new engine should not leak.

a properly placed seal in good condition should not leak.

the rear main is meant to keep fluid in. not let it leak. it should be bone dry.

and why are you waiting 2 weeks??? if you had a problem taken care off, and it's not fixed then TAKE IT BACK RIGHT AWAY....no offense, but the dumbest thing you can do is to keep driving it before you go back with a complaint. i know...i used to work at dealerships.

take it back. tell them you want the rear main seal replaced. that requires droping the oil pan, which will require replacing the oil pan gasket. tell them that when you come to pick the jeep up you want to see the old rear main seal (which is a 2 piece seal) and the old oil pan gasket, and that it better be as dry as the desert.
