Without wanting to be too flippant, it could just about be anything from terminal death rattle to a loose screw vibrating as noises are really difficault to type....

Is it when accelerating/decelerating, lots of electical load or not, aircon on or not, when last oil change etc etc....

If poss, how about recording it on a mobile phone, for instance, and posting up on Photobucket so we could listen??   :y

(my bet is the exhaust heat shields being loose..... ;) )
