I Just Purchased A New 2005 F150 Supercrew With A 5.4 And In The Morning When I First Start It Up It Will Blow Smoke For About 10 Seconds, This Only Happens When It Sits Overnight And Will Not Do It Again All Day. I Took It Back To The Dealer And They Said It Was Water Setting In The Exhaust And It Was Just Steam. There Is No Oder Or Color. Only White Smoke Any Ideas??

 

its possible, white steam is water, and the exhaust does collect water as you drive, water is a normal byproduct of a well tuned gasoline engine

 

I was under the impression that water is a natural byproduct from the cats. In either case, nothing to worry about. Tis the season for frosty windows and puffy tailpipes in the AM.

 

Sounds normal to me. So long as it ain't blue or black and you ain't losing coolant, don't worry about it.

 

You mean this:

Normal

 

Water is a product of combustion.

 

King Vinnie, that video is entirely TOO short. Awesome tone! My gf thinks I'm insane how I can't hear her sitting right next to me, but when a good exhaust fires up I can hear it in my sleep.

 

Did the dealer laugh at you ?

 

Heres a longer one scorpio333:

No worries bro. You will have that on your chilly mornings. Welcome to Fall.
