It could be either debris. Or intercooler or radiator bushing im trying to remember but or air filter rubber that holds the air filter box in place. Theres a lot that could be.
I did my rdu and had some clutch material there. But nothing mayor. I did it at 26k and i track thos truck before. Im kind of worried about my ptu because i did have a overheat code before.. 😅
