i got a weird problem going on once in a great while. i know white smoke is a really bad thing with diesel but i have now 8000 something miles on my truck and three times now when im on the high way and get on it sometimes white smoke will come out and then the truck is fine. it did it once before i even put my dpf delete on or did the chip. and it did it for the third time today and the truck runs fine still. so i dunno wat is causing can any of you guys relate or help me out.
