The smoke is thick white and irritates my eyes, and i can hardly breath. I basically have to hold my breath. For instance, it doesn't smoke as much when i'm driving casually but i still smell a little coolant. It's when i push the car a little. (my car still isn't tuned yet, and i don't pass 4000 RPM'S).

The return line on the turbo is fine. There isn't much shaft play with the turbo.

what i'll do is check the turbine side of the turbo to see if there is oil, but it still doesn't make any sense... the smoke would have a blue tint to it...
