You don't mention how many hours/miles the turbo has on it or how the car is used. For racing applications the turbo is considered a wear item and could be to that point.
If you are having no issues with oiling/scavenging you might borrow a good used turbo and a zork from a fellow racer and swap it in (removing the oily muffler). If it stops blowing smoke your old turbo was worn out.
