Is it normal?

Is it normal to have a small puff of white smoke immediately after starting? It lasts about 1-2 seconds and then it goes away. The truck runs fine, just like it always has. The reason I ask is because I don't remember it ever doing that before and I have had it for about 2 years. I just passed 115xxx miles.

depends on how cold it is and how quickly it goes away

I would say its normal if its only a couple of seconds. Mine does it for a few seconds and then clears up.

The temps lately have been in the 40-70 degree range.

might want to check your coolant level. if it is low it could be an egr cooler leaking. 6.0L is notorious for leaking over night and puddling on the rear cylinders causing white smoke on cold start ups. it could be the early stages of leaking also.

I'll subscribe to the cooler temps causing the glow plugs to cycle a little longer...which results in a couple of seconds of white smoke until she warms up.

sounds normal... all of mine do it

Thanks a bunch guys! I'll keep an eye on the coolant level, just in case.
