oil coming outta exh. pipe at start up

oil coming out of exhaust pipe at start-up
First of all, yes, the car is running super rich . When I start the car, oil is sputtered out of the exhaust pipe. What does this mean? At first I thought it might be gasoline, but now I think it may be oil because it leaves little black stains where the rear pipe is. If it were gas, I am assuming there would not be any stains.
BTW, my motor is rebuilt with about 7K miles on it and I am running the Apex single turbo.
Any info appreciated.

Thanks - Bobby

If this happens during a cold startup, check to make sure that what are seeing is not just water with exhaust soot in it. That is normal. And, yes, if you are running rich your rear bumper will turn black.

If you are getting oil out your exhaust and it actually is "wet" oil, then most likely your bearings on the turbo(s) may be shot.

I really thing you are just seeing water, and the soot is from the rich exhaust.
