XJ rear main seal: replace or leave alone?
While having my 93 XJ I-6 auto inspected by the dealer, he diagnosed an
oil leak as coming from the rear main seal. He suggested that it wasn't worth it to get it fixed, and suggested I just keep tabs on the oil level. A few days later, I had an independant mechanic change the front differential fluid (dealer said there was water in there, but there wasn't- go figure). This mechanic said that the seal might leak a little oil for a time, but then catastrophically fail at an inconveniant time. So, any ideas if I should have the seal fixed or leave it? At the moment it's slow enough that it's not even an annoyance. -- Monte Castleman, <<Spamfilter in Use>> Bloomington, MN to email, remove the "q" from my address |
Re: XJ rear main seal: replace or leave alone?
Ill bet you 10 bucks right now that it isn't your rear main seal. Its your
valve cover. Wipe your finger along the back of the head near the firewall. If its oily, there's your leak. If not, the rear main is a breeze to replace. The only hard part is cleaning the old stock original gasket. http://www.jeepin.com/features/rearmain/index.asp KH "Monte Castleman" <qmdcastle@skypoint.com> wrote in message news:vs8ijdfvff1a86@corp.supernews.com... > While having my 93 XJ I-6 auto inspected by the dealer, he diagnosed an > oil leak as coming from the rear main seal.

Re: XJ rear main seal: replace or leave alone?
If it leaves a puddle, then it could be the rear main seal, if it only
leaves a drop or two then its the valve cover. That was my experience... everyone said it was my valve cover but there was much more oil on the garage floor than was coming down the back of the block. I don't know if I would call it a breeze as Kevin did, but its not too bad. I had the take the passenger side motor mount off to get the oil pan off. Then you have to be very patient when installing the new seal so as not to damage it.

The valve cover gasket is a very common oil leak, as the oil runs rearward and down, main-seal happy mechanics may misdiagnose it as a rear seal. As for sudden failures of main seal, guess it could happen, never heard of it. And the seal is reasonably simple to replace anyway. -- Still a Raiders fan, but no longer sure why. |

Re: XJ rear main seal: replace or leave alone?
A leaky Valve Cover Gasket looks amazingly similar to a blown rear main
seal. I would be looking at the VC first. Then, if you really do need a rear main, it is a pretty easy fix in the grand scheme of things.

Re: XJ rear main seal: replace or leave alone?
I didn't see any confirmation from the mechanic at all. What he said,
according to the poster, was that it might leak a little for a while, then fail catastrophically at an inopportune moment. The mechanic may very well have given a backup diagnosis, but the original posted did not tell us of it. All we know for sure is that the dealership said the rear main was gone. We all know that this is a commonly mis-diagnosed problem, and we should not be surprised that the dealer might get it wrong. "L.W.

All it is, is a statement that if it is leaking, it can leak for a long time before it completely fails. Despite all of this, we all know that the Valve Cover Gasket does a very good imitation of a rear main that has gone south. Before anything else is done on the rear main, it must be confirmed that the VC gasket isn't the real problem. Then, if the rear main is gone, the repair should take about 2 or 3 hours for a shop, and 3 or 4 hours at home. > God Bless America, ßill O|||||||O > mailto:-------------------- http://www.----------.com/ > > CRWLR wrote: > > > > I didn't see any confirmation from the mechanic at all.

All it is, is a statement that if it is leaking, it can leak for a long time before it completely fails. Despite all of this, we all know that the Valve Cover Gasket does a very good imitation of a rear main that has gone south. Before anything else is done on the rear main, it must be confirmed that the VC gasket isn't the real problem. Then, if the rear main is gone, the repair should take about 2 or 3 hours for a shop, and 3 or 4 hours at home. > God Bless America, ßill O|||||||O > mailto:-------------------- http://www.----------.com/ > > CRWLR wrote: > > > > I didn't see any confirmation from the mechanic at all.

Re: XJ rear main seal: replace or leave alone?
Jeff, I will remind you, I used the term "seamed" which is like
guessing, right? Anyway, the mechanic set him up for the kill, as I did in those days. What it actually takes and the Flat Rate, are two different things. Guess which one will be used.

JD, I did indeed go to Park Jeep, not because I like them but because they were offering free vehicle inspections and I had the day off, so I figured I'd take it in and see if they turned up anything that needed to be dealt with before winter, having no intention of paying them to do the actual work. They quoted: 1. Replace Front differential fluid (contaminated by water) : $75 2. Replace missing exhaust clamp: $58 3. Replace rear main seal: $550 My regular mechanic, (the one I emailed you his name and address) wasn't available that day, so against my better judgement I called another place I was familiar with- an inner city outfit, and they quoted $45 for both 1 & 2. They're the ones that said the seal might suddenly fail, and quoted $350-$400 to replace it. Previously this place had tried to tell me my drive chain needed replacement. My regular mechanic, who opened the transfer case in order to replace the seals, found nothing wrong with it. Thanks for the recommendation. Might be good to see what someone who works on 4wd stuff all the time but is not a dealer has to say. Everyone, I'm pretty sure it's not the valve cover gasket, since that was replaced a few months ago- It was obviously leaking oil on top of the engine. (Also replaced the O-rings on the filter adapter). I've not washed the bottom of the jeep since then, but the oil does appear to be fairly fresh, and looks like it might be coming from between the engine and the tranny. It's leaking enough to give the bottom of the tranny a good coat of lubrication, but is not really enough to drip onto the ground yet. Why might the dealer think water got into the differential when it hadn't, or were they just putting me on? The fluid needed to be changed anyway, but I don't like being lied to.

The split main seal is is a rather weak design and can require frequent attention on some Jeeps, virtually none on others. ( My '94 YJ gets a new seal about every 20k miles.) |

As I pointed out above, mine would leave a puddle when parked after a drive.
