Keep an eye on your oil level.

Have you ever changed your crank case filter? How many miles on the truck?

Is the truck deleted or stock? Fill us in. Smoke all the time or sometimes? My 2008 f250 used to roll blue smoke for a few miles once it started to regen.

Is it consuming oil? If so how much? I would check the turbo first.

What programmer or box are you running?

Keep a close eye on the oil it may not be oil consumption causing the smoke. If so it probably isn't the turbo.

We need more info. List every single mod on the truck. Brand and all.

Can you hear a fuel knock or any strange noises under the hood?

If it's not consuming oil, and it has no loss of power, or fuel knock, that makes me think there is a problem with the box not working correctly. Will it smoke at idle so that you can smell the smoke? There will be a difference in the smell between oil burning or smoke due to fueling issues.

Did it just start this? Blue is normal for cold diesel and depending on the fueling program, would do it more before the engine warms.
