Demandated and pushing soot past the puck.

Now, i don’t know where the soot is coming from. I feel there must be an exhaust leak somewhere on the motor that is getting blown around while driving and using the engine fan and it had just collected on those crossover tube joints??

Anyhow, I feel a lot better about it now and I will pressure test for exhaust leaks when I get back home.

at least you know its ok to drive. that is the most important thing.

when you re-install that "hockey-puck" .. make sure you remove the metal gasket for that joint that is normally there. - It has been found that sometimes, when the gasket is still present in the joint.. it holds it apart just enough that it does not clamp the "hockey-puck" very tight. It either leaks.. or the puck vibrates and eventually has a chance for the edges of it to break off. Without the gasket in the joint, the puck itself will seal the joint.. and be held much tighter. - just letting you know.
