LB7: White/light tan soot on bumper

[diesel53]

What would cause this?? The truck only has 100k miles on it. Im guessing an injector but I didnt expect tan soot. I have not seen it haze at idle or any other time yet.

Its not the head gasket from what I can tell. Truck is completely stock by the way..

Truck needs a wash? Just funnin...all filters clean, do you use a fuel additive? If there are no lights, it runs good and your not loosing and fluids clean it off and keep an eye out for things! Nothing to worry about till there is a problem.

Thanks, everything is good so far. It ran diesel klene recently but Ive never seen that in any other truck I ran it in. Ill just keep an eye on it. Thanks!
