White Smoke on Start up?

Hey guys, ever since I got back from a road trip to Oklahoma towing a 4 horse goose neck, I have noticed that my truck gives a little puff of white smoke on start up. This wasn't the first time towing, it was just after this trip. Truck has 18,500 on it and it is completely stock except for the 4 inch straight pipe.

Early signs of EGR cooler going out, water in fuel, unburnt fuel, or bad glow plugs is what I think could be causing this.

Damn, I knew it was something not fun. I know there's no water in the fuel, because I've ran through about six tanks since then.

I believe they have a flash to fix this condition.

on a 6.0 i dont see it being glow plug issues they dont give many problems for that , im thinkin more along the lines of youust got back froma trip, and i have a feeling the egr valve is sticking open a little , that may sound crazy, but o a rip is when egr function is used the most , so it may be trying to stick, and has this truck been reprogrammed to the latest calibration, that will help also

Last time the truck was in for service was in July I believe, but I don't remember them flashing it at all so probably not. Quick question, when does the EGR open and close? How does it know?

The EGR valve is always cycling open/ closed under pressure. It is pretty easy to pull out if ya wanna take a look at it yourself. Stump did an EGR valve write up some time ago.
I had my first EGR issue and Ford corrected it with flash. Each time you get flash ...... it is possible to loose some mpg. just my .02 worth
