Blows White Smoke out exhaust after idling for a while

2011 6.7 f250 cc 4wd with 80K miles is my rolling office I leave it running most of the day while I am on the job site.
Yesterday the truck idled for a couple hours I started going down the road the truck was blowing thick white smoke for 3/4 of mile. This has happed a handful of times before. I searched the threads on the site and couldn't find any post with the same problem.
Anyone else have this issue ?
Any ideal what could be causing this issue ?
Thanks in advance

Hi Ty,

Since you're concerned, I recommend swinging by your dealership so they can take a look. Once you have a diagnosis, touch base with me via PM if you need additional assistance; I'll check out options. In your message, please include your name, daytime phone number, VIN, mileage, and servicing dealership info.

As long as there's no other running issues, missing, surging, etc, or trouble lights on the dash... the dreaded "Wrench" light... sounds like a classic case of "WET STACKING", liquid fuel covering the combustion chamber, pistons, rings, etc and buring off when the engine is put back under load and heats back up again.

If you're gong to leave your truck sit for more than 10-15 minutes, you should shut it off.

I didn't think the ECM let the new trucks idle that long anymore.
