Are you sure it's not a problem with your Secondary Air Injection System?
If you have any blowing pipes or connections, that's when this system is
operating.

Ah, right, won't be the SAIS then, as that has it's own pump and you would
hear it easier with no revs.

Seems a fairly common problem on the V6, i have both sides to do on my one and Haynes says you have to remove the engine to get off the passenger side bank :( OMFG :'(
