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.

Re: diesel oil for wrangler?
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> |
