Soot in the overflow tank? Is this possible?
Hopefully someone can shed some light on this mystery. Over the holiday weekend I did a motorcycle trackday at Willow Springs here in So Cal. So I was prepping the truck to tow the toyhauler, increasing tire pressure and checking fluids, etc. and I noticed a dark shadow inside the radiator overflow tank. The truck has a tendency to blow a little coolant now and then but nothing too crazy. So I decide to reach my finger in the tank and see what this darkness is and it feels sooty, or even a better description...resiny.
Is this due to overboosting and slightly blown headgaskets or what?
I have a Banks 6gun+SL, and occasionally get on the throttle pretty good.
I have no fluid leaking on the block, or in the driveway, nada nowhere.
So Im wondering if anyone has ever heard of this phenomenon before?
Thanks much in advance.

That was with blown headgaskets and only 7 injectors!
