I'm no engine expert, but in my experience when a cam goes bad the engine needs to be disassembled and cleaned out. I helped my brother with his LS6 after it had a cam go down and we just pulled the cam and replaced it. About 30 minutes after installing the new cam it was down again. The oil passages had filled with metal from the first cam and it caused the new cam to go bad quickly. The next time we disassembled the engine and completely cleaned the block. It didn't have any more cam failures after that.
