White puff of smoke at startup?

[sdeeter19555]

Had this happen about a week or so ago, and has not repeated.

 

Started the truck one morning and got this big puff of white smoke...not condensation, smoke. The main reason I noted it was that I started the truck then went to close the tailgate...stuck my nose in it and it really didn't have an odor...although it hung in the air for a while.

 

Since then, I have watched it for a repeat. The only thing i can attribute it to was that I had started it briefly the night before (it ran about 30 seconds) and maybe it was something left over in the exhaust system? Thoughts?

Got any warranty left ?

Just the drivetrain...

And I have probably started it twenty or more times since then, and it just sat for an entire week until today and didn't do it. It only did it that one time...so far.

I could agree if it did it more than once...and besides, it didn't smell like coolant.
