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.

That does sound like manifold gasket

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 :'(

I was looking on vxon this morning  ::) and there was some one asking the same question but the answer they suggested was to change the oil  :o Now even I know that this is likely to be the gasket  ;) I sent him a pm suggesting he try OOF  :y I think I suggested this site to a couple pf people today  :y
