I've noticed in my 06 CTD when I keep her plugged in overnight, that the truck will put out white smoke during my drive to work. But when I drive it home after 9 hours of sitting in the same 20* unplugged, there is no white smoke. By smoke I mean the white crap that you see gassers pump out when the temp drops. My fear is that the block being warm is causing moisture to condense inside the engine somewhere. It was my understanding that diesel's don't create any moisture during combustion or whatever and that is why they never pump out the white stuff, so the fact that mine is smoking has me worried. Do I have anything to worry about? Thanks.

There was a TSB reflash for long crank and white smoke on first startup of the day. Can not find it right now. Your 06 falls under that TSB.

Smoke while driving depends on your engine temperature and outside air temperature.

I'm not too sure that it's smoke but I know what you're talking about; I think it's steam or something....kinda like when you see your breath on a cold day . I've noticed that my truck does it too for about the first ten minutes of driving and seems to do it more when the truck has been plugged in.....I think it's normal, I don't worry about it, the truck starts and runs good, and I'm not making oil or losing coolant......
Also temps have to be down in the 20's or colder before I really notice the "smoke".

white smoke= unburnt diesel in most cases


yeah the black stuff is not un burnt diesel, it's just a by product of burnin the diesel really fast

Black smoke is also unburnt diesel and yes white smoke on startup can mean injector problems if it is indeed smoke. White can also be coolant or just steam/condensation.
Burnin' diesel really fast won't cause ANY smoke if it is a complete burn.

The block being warm is NOT causing moisture to condense inside the engine somewhere..

When the engine is cold the timing will advance to help eliminate the white smoke.

If your truck is parked in a garage and you have the block heater plugged in, the timing will be on a standard timing table when you first start the truck. This might account for white smoke when you first take off.

Next time you start the truck, take notice if the grid heaters come on and cycle.
They should in cold weather. this warms the air to help start the engine and helps eliminate the white smoke.
