Ok, I've got a brain teaser for you... I have a 93 Legend Coupe, Type II, 6-speed, with 292,000 miles on it. I've had the car since 48k miles. It's my daily drive (obviously!). Since 100,000 miles I have put synthetic oil in it.
Well, recently I took the car into the dealership to have a TON of stuff done to it. Ever since then, when the car idles for a while it will blow out oil smoke from the tail pipes for a few minutes. Drive the hell out of it for a bit and it goes away. Sit a while idleing and it comes back. The smoke is definitely oil but some times it seems like steam (I think). Now I've checked the radiator and there's no oil in it. The car does not blow any smoke at start up, only after it's been running for a while. Any ideas?
