You will have to get under there and have a look. If you have lots of smoke you may have oil dripping on the Catalytic Converter. If this is the case it could potentially cause a fire. I would guess that if you have smoke from the passengers side it is more likely to be from the front cover or front crank seal dripping on the converter.

You took it to a shop for a repair, and it came back worse than it was. They obviously messed something up.

Unless you specifically told them to just change the rear main. Meaning you or someone pre-diagnosed the leak.

well the rear main seal was definitely leaking, i saw it my self, and yes i did tell them to change that, however when they dropped the tranny they said the seal on the tranny side wasnt good either so i told them to change that as well since it was out. but the thing is, even though the rear main was leaking, it wasnt smoking at all, it was just dripping out, this seems like its coming from somewhere else that wasnt leaking. I had told the guy that i want this car to not leak any motor oil or tranny fluid, that to take care of the leaks if he spots any, and he said it was only the rear main seal and the tranny seal along with one of those connectors that plug into the tranny... so now my question is to you all, he said bring it sat (tomorrow) so he`ll clean the bottom and wipe out everywhere so he can see exactly where its coming from.. if its the main seal, he obviously has to do it again, but if its something else, should i flip out at them? o yeah another thing i think they had put synthetic motor oil, i dont know why, but would this cause the motor to "spring" a leak from crankshaft seal or timing cover?

Imo, he should have thoroughly cleaned (maybe steamed) everything the first time if you requested a non-leaking engine.

I wouldn't flip out at them if something else is wrong. If you asked for your car to not leak, simply remind them of that fact. If it turns out to be something that would have been easily noticed, ask them for a break on the labour since it should have been done all together when you had it in. If they disagree with that, then it's time to start flipping out. People make mistakes, everyone should have a chance to correct it and that includes a business too. Yelling often gets you less far than being understandable about it. Even if they did it after being told off, they might not do the job to the standards that they would give to their nicer customers. Just imo.

if it is the main seal ( put in wrong or such) i dont want to pay a penny because it should have been done right the first time.. i was thinking about that before i go and flip on them cuz they could mess up something else if i go yell at them so... dropped it off this morning they`re going to call once they check it out, i figured they do good work since they been there pretty long and all 10 lifts has cars on em and cars anywhere else they can put em, go figure

Flipping out definitely won't help. Really on a car that old I'd be shocked if only one main seal were bad. After 20+ years the flexible material, whether natural or synthetic, has shrunk and hardened. Moving the crankshaft position in the slightest to change the rear main seal could easily disturb the front main's lip enough to accelerate leakage there.

I'm just saying as someone who's driven a lot of 20+ year old cars & trucks, that even with the best of intentions when you're dealing with plastic and rubber, sometimes **** just breaks.

okay got the car back, the mech said that he tightend the oil pan and ran the car on the lift and didnt see any smoke or motor oil but by the time i got home, the car was in a clould of smoke again. it wasnt smoking AS bad, but still smoking none the less. i called, he said he sprayed cleaners on the underside and it needed to burn off.. so me and a buddy drove the car for about 5 hours last night and still was smoking by the end of the night, and had to top off motor oil. ideas at this point fellas?

guess you`re right, if you want something done right gotta do it yourself. its just 800 bucks down the drain

When I overhauled my taurus transmission, I replaced the rear main seal as well. I also noticed a lot of smoke from the front and back, but diagnosed it to the two exhaust connections (from the exhaust manifold to the assembly I had to remove in order to drop the sub frame). While the shop manual did not call for exhaust flange gaskets, I bought two, installed them and the smoke disappeared.

Good luck.
