i have a turbo that spits oil out of the exhaust side

i replaced it with another turbo

still the same problem

any idea what could cause oil in the exhaust on aturbo car without a seal being blown?

 

A little bit isn't abnormal, how much oil are you getting out of there? You may need to tap off of a different oil location, you might have too much oil pressure. Unlikely, but maybe.
You may have an oil drain problem too, if the oil isn't draining back to the pan correctly it might be pooling and leaking past the seals. Turbo might be too low, drain line might be too small, etc.

Is this a stock turbo setup or something you put on?
