Everyday when I first start my 2006 F350 Lariat 6.0 Powerstroke, it has a little bit of white/grey smoke coming out from the exhaust tail pipe. It's not that cold here in South Carolina over night either around 68-75 F°. My coolant temp reads at 108 and oil reads at 100. When I press the gas it shoots alot of white smoke through tail pipe. But when the engine is warmer, it doesn't shoot white smoke no more. Is this normal? Anything is helpful.

 

Not normal.

Still have a functional EGR system?
Any particular smell to the "smoke".

Pics, and especially videos, can help.
A good scan tool with thorough code reading is a requirement for a 6.0L owner.

 

Yes I have an EGR. And I'd have to find out what the smell is like tommorow. When I first start the truck

 

White smoke can be raw fuel from leaking injectors, or coolant from a leaking EGR cooler. Both can be serious (or get serious quickly).

 

So i figured out it's my glow plugs. Rough start in mornings, alot of white smoke when first cranked and fuel efficiency is decreased too. Check engine light on it.
