just noticed this happen this evening. start the truck and a small puff of white smoke comes out. every time i start it. never noticed this before but havent really paid attention to it either. good or bad? injectors or a hg issue maybe??

 

Dose it go away? Power ok? Fuel pressure ok? VFO valve ok? Oil in water, water in oil?

 

could be water in cylinder ( investigate)or timing slipped
