Hi all! So, seems the majority feel that at idle, blue smoke is bad injectors. Is this correct, or could it possibly be something else? Turbo seals maybe? I just HATE the thought of spending a ton of money for stupid overpriced injectors. My truck is an 01 with 150K. Out of warrenty. Thing is, it still runs good and has no fuel in the oil that I can tell. Tried the paper towel test, and looks good, not overfull either. Any suggestions?? Will it hurt it to run it that way as long as there is no fuel in the oil?? I can't afford the injectors right now......might be cheaper to trade for newer!(hate to say it, but maybe a cummins??)
