?Fuel? from exhaust

[dboyw]

Well the 3.5 hour drive home today in the drifting snow was fun...

When I finally got home, I saw this coming from the exhaust. It has no smell that I could tell.

Any concern, or could it be from the 35mph drive home in the snow just didn't let the truck get really warm? This is the only time I have ever seen this.

Thanks

Are you sure it's not just water? Water is a byproduct of the combustion process, and after it travels down the carboned up exhaust pipe it can be all kinds of colors when it exits. If you are driving real slow in the snow, and not using the engine much, you're not "pushing" this water out with the exhaust flow, and it puddles up in the nooks and crannies of the exhaust system. Coould just be that the nooks and crannies filled up and that's the little bit that DID come out after you stopped.

X2 with what bigrigr said.

Condensation that doesn't normaly form... due to temps, slow speeds, varying but mostly..low rpms= Soot residue mixed with water due to whats been mentioned.

In the Heavy Equipment world.. we usta call it.. Drool.

Like the Slobber lines on Big Truck (bigrigr ?) or Dozer stacks ? In the Winter ?

I wouldn't worry about it dboyw.
