First off, the truck is a 2004 RCSWB 1500, with a 5.7 and 4x4. I was changing the header gaskets and oil, and replacing my belt this weekend. I decided to do the header gaskets first. Upon removing the passenger side, I seen what looked to be a demolished pulley. It is right below the tensioner, and slightly to the passenger side. I will get a better picture, either later today or tomorrow when I get the fan shroud off.
