OK. my exhaust has been getting progressively worse and worse, missing gasket, and resonator trashed completely. but tonight, something definantly went wrong BIG TIME with engine, its just hard to tell WHAT.

The best way to describe it is a 'clack' looking in from the passengerside of the engine, underneith the plastic BOXER cover, above the differencial dipstick, there is this very large blue gear of sorts. infront of the gear(towards front of car) is this metal disc shaped thing. it APPEARS to have wear marks on it. I THINK thats where the noise is coming from. its INCREDIBLY loud. rev the engine, it goes away. its only at idle and low speeds, but its insanely loud. suggestions?
