diesel oil for wrangler?
I have a 91 wrangler (6 cyc, manual trans.) and it has a leak at the
front bearing seal. (~$700 to replace the seal) The mechanic suggested I use 15W40 diesel oil (since it is thicker) together with some sealant additive to minimize/eliminate the leak. However the guy at PepBoys says it is not such a good idea to put diesel oil in the jeep, plus it will have problems with cranking/starting in cold Jersey winters. What do you guys suggest? Ozzy... |

Replace the seal. If your reasonably competant with tools it's not that much of a job. Just takes a while to break everyhing down. But before you do that make darn sure it's not your valve cover that's dripping down.

Re: diesel oil for wrangler?
Diesel rated oil won't hurt anything, but probably won't help either. Best
just to replace the seal. If you do use "diesel oil," try Chevron Delo 400 or Shell Rotella, two of the best. Both available cheap at Walmart. Robert Bills KG6LMV Orange County CA http://www.outdoorwire.com/4x4/jeep/...p-l/billsr.htm http://www.RobertBills.com |
Re: diesel oil for wrangler?
My theory is that thicker oil will not flow through the relatively smaller
oil passages as well as oil intended for your engine. You may get insufficient oiling of bearings and especially pistons and rings if you use it. Do yourself a favor and fix the leak instead. I am guessing two hours labor tops for the job. No way does this add up to $700.

Well, here is what says in the estimate;
Crankshaft main bearing seal replace (B) 7 hours x $ 80.00/h rear main oil seal $10.00 oil pan gasket $40.00 oil and filter: $25.00 I think I was wrong in the first post, this is rear main oil bearing seal, is it not? Is $700 still too high?

Many of those jobs can be done in less than half the time, but they still charge the full 7 hours. Also, you may want to shop around. I don't know about your area, but here $80 per hour is high even for the dealers. Our dealers are about $60-65, but the independent mechanics are even less, usually in the $45 range. Chris |
Re: diesel oil for wrangler?
Rear main makes more sense for that kind of price. Is this one of the model
years where they have to remove and replace the transmission to get at the seal? If it is, consider replacing the clutch at the same time.

Rear main seal on the crankshaft. > Is $700 still too high? Yes. If it's a split rear seal that's about a 2 beer job basically you just empty the oil, have a beer, drop the pan, loosen the back two carrier bolts, and remove the seal. Then scrape off any old oil pan gasket, put the new seals in, torque the carrier bolts to spec, a little sealant, gasket, and the pan. Add oil, and have a beer. While your in there may as well clean the oil pickup screen. Just remember to put it back.... Best to have a service book though. |
Re: diesel oil for wrangler?
Do you have the plastic valve cover? If so, it is almost certainly
where your leak is coming from. Check very carefully, no matter which valve cover you have, for leaks. They almost always look like a main bearing leak. Wipe it down good, or take it to the car wash and spray it off, or just replace the gasket, (it's cheap) and wait a few days to see what happens. Good luck, happy holiday Tookie |

Even on an 88 that, to all appearances, never had the pan off in it's 150,000 miles I spent under 3 hours including scraping off the hardest, nastiest gasket I've ever seen and pounding til my arm was tired before the upper seal half finally gave. Of course, I was smart enough to pull the starter and tranny mount (so that I could jack it up) to get enough clearance to get the pan out... -- Will Honea <whonea@codenet.net> |
Re: diesel oil for wrangler?
Ahh, so they sound like they are charging you to remove the engine to do
the seal change... It 'can' be done from the bottom in the driveway. It is a good half day's job for an amateur wrencher. A couple hours for an experienced one. (the gasket clean on the oil pan can be the hardest part) Before you think more on this, you should do yourself a favor and check for the 'normal' cause of a 'rear main seal' leak. Nope, it isn't 'normally' the seal. Start the engine up and run it for a bit, then take a clean rag and wipe it around the back of the engine head just below the valve cover by the firewall. If the rag comes out with oil on it, you have found the leak. The valve covers are really prone to leaking and because the engine is tilted, the oil runs down the back of the engine. The bell housing has a hole at the top and the oil just runs right straight down doing a real sweet imitation of a blown rear seal.

Re: diesel oil for wrangler?
Diesel oils have a higher level of calcium based detergents I thought... I
can only think that the added cleansing would tend to loosen up large amounts of exactly what we would rather not have floating about in our oil sump. I can't see it helping too much in any case.... I would go for a new seal... "Robert Bills" <rdbillsjr@aol.comxxxxxxxx> wrote in message news:20030703132146.06709.00000037@mb-m11.aol.com...

FSM for the 88 MJ/XJ just says to remove the starter as do both the Chiltons and Haynes books I have. On both the 88 MJ and 91 XJ, you actually have to jack up the rear of the engine a bit to slide the oil pan back past the bellhousing - that's safer and easier if you unbolt the rear tranny mount where ever it's easiest to get at. That might be a tad tougher on the YJ with the skid plate and no lift but pulling the tranny sounds like make-work to me - you would have to pull the flywheel/flex plate for that to do any good. -- Will Honea <whonea@codenet.net> |
