It's a weird noise... hard to describe but I'll try... I think it is coming from the alternator - not sure, it ONLY happens when the engine is at idle @ operating temperature. Anyways, it sounds like a cat eating (ya know, the nyahnyahnyah noise they make) only more tinish. I wish I could get an audio clip of it... hmmm.. it's not a rattle or a squeek... dangit.

Re: car 'chatters' when hot... (slumberbunny)

could be the water pump, too. run the car without the belt for the accessory in question to troubleshoot- if you don't have power steering or a/c then see if it goes away without the belt and check for play in the pulleys to try and narrow it down.
edit- one of those mechanic stethoscopes may help, too.
