light white smoke after sitting
after my truck sits overnight or at work all day, i on occasion have some light white smoke and less than smooth idle. i dont know that id call it rough, but its not perfect. and it cleans up as soon as i start driving, although burping the throttle doesnt necessarily clean it up
truck has 155,000 on it. i run 5 mic filters every 10K miles.
could i be lucky and this be a loose tube or is it more likely an injector?
truck makes no oil. EGTs are normal.
if its injectors, what is the fastest for the money way to test them and replace as necessary? downtime is money, so i dont mind spending a little more to speed it up, but i dont want to drop 3 grand on six new sticks either......

It only seems to do it after it sits 8 hours or so, but it seems to be getting more consistent. Am I going to melt a piston if I drive it for a week? I'm thinking of just ordering two injectors now and pulling all six and takin them to cummins for testing. The gamble of course being that there's not more than 2 bad.....
