What causes this and how? It was just rebuilt due to having the same problem, but obviously wasnt taken care of. Mostly after the car sits over night does this happen, it does happen on occassion just when driving and smokes pretty bad then goes away, and I have tried it on 2 cars and the same results so I know its not the motor. The turbo is a TE-61, I think the center section might be bad but how?? Can I use my good stock center and just change the wheels?
