sidewinder1350 Posted June 26, 2005 Share Posted June 26, 2005 Hello everyone, I have a r model mack 72' with a 6cylinder in it, it also has a turbo. I am not a expert on diesels this is my first one, It smokes, blue smoke, right when you start it , it thins a little after it warms up but it still is blue, when I give it throttle it gives a big puff of white and a little black then to the light blue. Could this be engine adjustments, or maybe the turbo is passing oil, what should I check first . Or it might be the rings and sleeves. It starts right up should I do a compression test first maybe. well knowledge hopefully will be shared, or like always Ill just read my butt off, thanks everyone have a good day Quote Link to comment Share on other sites More sharing options...
