Is anybody else 6.7 cummins blowing white smoke when the engine cold. Yesterday started the truck and I notice white smoke came out and then I took off it started pour out more I gas on it. Then when it warm up it was fine. Today it did it a little bit but it didn't get as cold last night as it did the night before.

WAS IT SMOKE OR CONDENSATION... mine will blow a little condensation
might want to let it warm up for 5 min before you drive anyway

How COLD does it get in TX ?

it might be someting new with the 6.7 I have to get used to but I have owned 4 different diesel the one that did it before was the 04.5 and they did a tsb and fix that problem. I never had one condensation like a gas engine before and it did matter how cold it got.

This new motor with EGR, a throttle plate, and a VGT will warm up similar to a gasser...

Smoke, and quick heat...
