Exhaust Stain

***TWhaylen*** · #1 (**permalink**) 11-18-2008, 10:07 AM

So I keep my truck in the garage at all times and our garage floor is that normal smooth concrete. I was out sweeping the garage and noticed this area on the concrete that was stained and it sits right below where my exhaust pipe dumps. The outline of the stained area is like a yellowish sort of color, almost like that of urine (sorry but first thing that it reminded me of...lol) I am just wondering does this mean anything or would this color from the exhaust vapors be normal for a diesel? I have an '06 250 with the 6.0 Thanks for any help, and just want to make sure that it isn't a sign of some sort of problem with the truck.

Do you ever leave it idle very long in that spot? Maybe it's a heat stain????

Nope, I only have it idle maybe two minutes at most but when it is really cold out there is a lot more vapor.
