Smoking 6.6L Duramax My 2002 Chevy 3500 6.6L Duramax is smoking like a chimney at an idle (white smoke). There has been no coolant loss or oil consumption. It has 135,000 miles on it. It is showing no diagnostic codes. Is or has anyone else had this problem? Could it be the vacuum pump or turbocharger waste gate?
