Keep an eye on your oil level.

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

dave1985

i have 31.000 on it and i changed the crank case filter at 30.000 miles

SpeedyWS6

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.

dave1985

i got dpf delete k and n cold air intake it really blows smoke when the temp is around 200 but also does it when its still cold

SpeedyWS6

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

dave1985

i check the oil often and its not consuming oil what should i check in my turbo?

SpeedyWS6

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.

I only got a box (DPF-R) the delete is from the turbo back.4in into 5in pipe Yesterday I left work and it smoked for about 2 miles then stoped but the engine was still cold at the time

SpeedyWS6

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.

dave1985

at idle it smells like rich fuel coming out of the exhaust it really stinks but i have never smelled it while blue smoke was coming out

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.

dave1985

it started about 3 months ago. i think im gonna take it to my local shop Friday. if they put a programer on it will that let me know i got a fueling problem
