It seemed to respond more to some sort of pressure. The closest I've ever heard, was a catalytic converter had broken up and made a similar sort of noise. Doesn't really sound like a pulley or tensioner as it would sound more consistent and be in tune with the RPM. These engines are pretty complex so it's going to be either something major, or something minor that's tricky to access.
