Like several owners here, I recently started getting the white smoke on startup only after the truck has been sitting for 8 hours or more usually. It clears pretty quickly. The greatest amount of smoke is right when it starts then it tapers off and by about 20 seconds later its just about gone. By the time I drive off its completely gone. I've changed my fuel filter, I've run a couple of tanks of PS through it, haven't tried 2 stroke oil yet, and I'm checking my oil level at every fillup to make sure its not making oil. So, I'm pretty sure its an injector with a slow leak while the truck is off.

So my question is...should I even worry about diagnosing and repairing the offending injector(s) or just let it go? Is there any problem with letting it go (other than it might worsen over time)?

 

I would have a return flow test done on them just to be sure you O.K. A bad injector can melt a piston.
