2004 Honda Accord Engine Noise

My car is making this weird noise around the pulley and timing belt area. However, it stops when I rev the engine to 2 grand. It sounds as if something is loose or if a bearing is broke. The noise is hard to describe, it sounds like a ticking scraping sound. I have been reading that the belt tensioner pulley is a common problem, I wonder if that is the case. Any body with any advice would be appreciated.
