Thanks for the follow-up. I have a clicking that I can't track down, I pulled the side cover off of my timing gear because of this thread. Sure enough there is an aluminum cam gear. Funny part is I really don't hear it when it's cool out like it has been lately, and never until the engine is warmed up. I'm very suspicious now that after the engine is warm, the aluminum expands and that brings on the noise.
