I have a 2001 Ford F-350 Powerstroke 7.3 Liter Diesel that is puffing bluish black colored smoke when you take your foot off the gas pedal. The slower the vehicle goes the more smoke comes out. The smoke smells like burning oil or burnt rubber. Does anyone have any idea what may be wrong so I can fix it?

I just had the CAC tubes, O-rings in Y-Pipes and the Carm Reman Pedestal Asy replaced a week ago. It was dripping oil severely then. Now not dripping, just smoking. I believe the turbo oil seal is what has already been replaced, so does that mean it would be narrowed down to the valve stem seals?
injector o'rings or not torqued tight enough
