Ok here is the sound clip.This was recorded with the hood open right in front of the timing belt (where it seems the noise is coming from).
It doesn't sound that loud outside of the car with the hood shut or I'd be really upset. Its just slightly audible normally, but I recorded it this way so you could hear it better.
Again it sounds like its coming from the timing belt area, and its only at idle as far as I can tell.
Any ideas?
