I have a 2002 2500 5.9 that when started on a cold morning blows white smoke for a min then stops. When I stop some Where and get back in and start up it puffs white for a second. No loss of power no CLE no soft codes. Not sure of fuel pressure. I know I need a gauge. My question is is this somwthin I need to worry about or no? I just started seeing it the last few days. But the temp has been colder the last few days. Thanks for any and all help!
