My truck is white smokeing when first cranked and when you try to get on the throdle pretty good, seems to play out when good and warmed up. I do have an antifreeze leak but it is coming from around the tanks on the radaitor. It's had it since I've had the truck. But the white smokeing has recently started. Any help would be great! Thanks!

 

fuel is not burning completely when cold causes white smoke. as long as like you say it quits when warmed up then your probably alright

 

Mine does that too through the winter season. Nothin to worry about, like you said once it warms up its fine

 

thanks for the help

 

Ok...what about the white smoke (all of a sudden) and continues for 20 minutes straight? Wife had the truck and freaked taking it to dealership to look at. EGR valve or something else? We live in East TN and have had a significant amount of rain and cold these past 3-4 days....possibly water? HELP

 

my 04 started white smoking on day while driving, i ran a diag and a injector tip broke off in the motor and i had to rebuild my 6.0 don't whait to long. but that was a constant white smoke if it stops after awhile you might have an injector sticking open. some fuel treatment / injector cleaner my fix that.
