Question Whats causing the white smoke?

Recently my 06 started blowing out white smoke on occasion. it only does it when its been drove a little while and you come to a stop light or it sitting and idling. it will do it for 10 to 20 secs and let up. Anyone have any ideas what the crap is going on with it?

take it into the dealer, but odds are this is being caused by a failed EGR cooler

Thanks Marc, i've had it in once but they couldn't get any codes and said therefore there was nothing they would do yet. they didn't seem real concerned but i am tired of seeing all the smoke pass me at stop lights. there is difinetely something going wrong or they would all do this! I am going to take it back soon and have them snoop around some more.

Cool white smoke

Yah Marc, I gotta know. The 04 truck I got last month started it real bad. I thought it was my PPE tuner on 10 that did a number on the head bolts. The dealer said it was common and I can get her back in the morning. Is there anything I can do to stop this?

IMO, white smoke is probably an injector leaking somewhere. My 95 Powerstroke finally had the O rings in an injector to deteriorate and it started leaking fuel. It would smoke pretty heavy till it warmed up and the seal came back in tact.

I fixed mine by replacing the O rings on the injectors. I'm not sure if it's the same on these new engines, but that would be my guess.

Fix the whole Turbo EGR system where it doesn't rely on a VGT turbo that is prone to stick in an overboost or underboost condition. The overboosts are causing the EGR Cooler failures, there's no doubt in my mind. When your turbo is sticking wide open and makeing 40 lbs of boost, something is going to break. A 7.3 only has what? 11 pounds of boost or less? Can you immagine what a 7.3 would run like with 30 lbs of boost? You'd have to run loaded all the time to keep the truck on the ground.

Cool Smoke

Thats funny, My 7.3 hits 30psi with ease and has been up to 42psi for a few seconds. I was thinking she was coming through hood. I would like to have a 6.0 turbo on my 7.3. Hey Marc, is there a way to bypass egr cooler safely?
