Does it only do it when it's cold or all the time? If it does it all the time it sounds like you're burning coolant, maybe with a blown headgasket. If it only does it when it's cold it's just incomplete combustion and somewhat normal.

white smoke (alot of the time, but not all) is a sign of a dieing IP. Have the codes pulled on the truck, and hope you don't see a 0216. There are 2 kinds of vp44's, dead ones and dieing ones. If you drive a VP'ed truck long euongh, you will change the IP.

it mainly does it when its cold and the VP44 was changed not even 20k ago. hopefully that not the prob. but i will hook up my superchips and see if it pulls any codes, hopefully none tho.

Thanks Jturs

Hopfully that's not it. I had one pump only last 8k on my truck and had new one on a buddy's truck go out at 15k, but they were both heavy bombed trucks.
