Oil leaking out my rear main seal when I get on it?????????????? When I get on it I start leaving a trail of smoke. It is not a little one either. I jacked up the car today and noticed it was coming out of the rear main seal. The bottom of my car is soaked with oil. When I drive the car normal it seems to stop leaking. I just got the tranny rebuilt and change dthe oil recently. The tranny was not doing this until I changed the oil and raced it last night. I am thinking I just over filled it. WHAT ARE YOUR .02 ON THE SITUATION?????

Yeah, it looks like the highest point of leak is the rear main seal, but it was fine before I changed the fluid and raced the car last night.

No, you're not alone on this one. I too have a leaking rear main seal, which started after I installed my Spec II. So far I've changed the rear main three times, with no improvement. The only thing I haven't checked/replaced is crank walk (movement fore and aft of the crankshaft). Reason? Don't know how, and I'm not paying someone else to do it. I wipe down the bell housing and every oil change pull the tranny out and clean out the bell. BTW, I can strip the tranny out in just under 20 minutes now.

I have a 86 MOnte Carlo SS that does the smae thing. When you hold it wide open after about 1/8th mile it will start smokin like hell from oil on the exhaust. They guy I bought it off of said that he was sure he got the rear main seal in wrong. it does the same thing

LOL no man, they are talking about the rear main seal on the back of the motor behind the flywheel.
you are losing tranny fluid then right? which is leaking from your tailshaft seal?
you just got your tranny rebuilt how easy was it to slide your driveshaft in? normally after I rebuild a tranny its really hard to get the yoke in. maybe they didnt replace that seal or put a new one in or left it out!
You said "OIL", not "FLUID". we were soooo

when I looked at the title, I thought that should be in internal engine. I actually know 1fstGM, so I thought id chime in, hehe. glad to hear its not the rear main seal that is a freaking nightmare and a half.

If they put in a new pilot bearing they very possibly moved the plug in the center of the crank [right behind the pilot brg. it is easy to do if you dont know its there, it will cause a large oil leak. repairing the problem is not easy the plug has to be driven out [to the inside] then a new plug installed from the rear ,you will have to remove the pan to get the plug out. good luck getting the tranny shop to fix their screw up.

My bad I should have said fluid. What trips me out is that the first time I put the tranny in and filled it up and it was cool, but when I change the fluid about 400 miles later and top it off again this happens. It was just kind of weird to me. The smoking has decreased ever since, but I will have to check and see if it is leveling off or if it is because there is no more fluid in it. First impression was that I must have blown something in the tranny since it was the first time I raced it after changing the fluid, but I guess the worst it can be is just a bad rear main seal.
