If it is white, then usually its unburnt fuel, if its blue then its burning oil, when you are on boost it most likely is a oil leak on the inlet side of the turbo, if you let off and smoke billows out then chances are it could be a thrust seal in the turbo. Black stuff is the normal for diesels, just not as much as a Prime mover or Locomotive.  |
Quick note: white smoke is oil, black smoke is unburnt fuel, blue smoke is partly unburnt fuel, or fuel and oil.
