White smoke tells me that there is water in the fuel possibly. When it reach the combustion chamber, it doesn't combust, it turns into steam and out the tail pipe. This is just a guess though. I would think it has something to do with your fuel system. When is the last time you changed your fuel filter?

How many miles do you have on your truck? How often do you change your fuel filter? A signature would better assist you, not only here in this section, but all around. Are we working on a 6.5L, 6.6, LB7, LLY, LBZ, LMM, etc.?
