So, I just got me a 2000 Z28 with 130K on the clock. It runs like a champ, except for the noise under the hood. Sounds like I need some pulleys. I replaced the tensioner and idler pulleys for the accessories and the ac. I thought that took care of it, but this morning I heard something like a messed up pulley....?

What could be the possible problems? List em, and I will go and check to see!

I am a mechanic, but new to the "new" stuff. Any and all help is appreciated.
