I'm gonna have to chime in, after watching the video, I too had puffs of blue when warm,and that smoke is blue not white, have you seen white out of a tailpipe yet there is no mistaking it, I replaced my turbo problem has not come back yet, I plan on rebuilding my turbo to check it out, it is either ccv oil being sucked from valve cover into turbo then pushed through your intercooler then into the intake, or turbo seals going south. if you take apart your intake boost tubes you will be relieved, there is enough oil in there to lubricate a briggs and stratton 1hp motor
