Rear main seal

Well i just took it in to the shop and they had it for 1 day, i have to pick it up tomorrow, they replaced my rear main seal, I know that daryhunter has had this same prob, Do you think their is anyway possible that the 1704 superchips could have anything to do with that, I have not had a problem it seemed like intill i installed my SCMT or is it just bad luck. Oh and by the way nice to talk to you guys again.

Probably not! I have an early 03. I have had two rear main seals replaced at 3500 and 7500. I now have 25,000 plus and all is fine.

Mine actually had a bit of a drip before I started using the SCMT so I don't think that the problem is related to its use.

When I took my truck in, they first replaced a front seal of some sort and thought that would do the trick - didn't though. Brought it back the next week because it was leaking worse than ever and they next replaced an injector pump seal.

That went a long way towards clearing up the bad leak.

I had cleaned off the bell housing and surrounding areas when I changed the oil a week ago but when I looked under the truck this morning the bottom of the bell housing had an oil film and a drip starting to form. No oil spot on the driveway yet. I'll clean things up one more time to make sure that it isn't due to any remaining oil still dripping down from the injector pump seal. If it is still leaking, then back in again it goes.

What they did with mine is they put some kind of dye in it and told me to drive it for about 500 mi then they put a black light under it and they knew right where it was coming from with no messing around, but mybe they all do that i dont know.

My RM leaked at 200 miles.. First one didn't take.. They pulled the rear engine cover and 'created' another leak along with the second seal replacement.. Third one held just fine... Ran the Predator 'during' and 'after' the last rear seal.. Never leaked again, even with the Predator tune for thousands of miles until traded.. Dye check is normal procedure.. If you do your own oil changes, the oil will have a green color to it when drained..

They did put some dye in mine, or at least had it on the invoice under the parts.

Hope they got yours fixed first try.
