Did you find it? Don't know if your AIR set up is different - mine screwed into the metal pipe coming off the top/front exhaust manifold, then connected to a hose, right by the #4 cyl coil pack.

Yes,I finally found the bank 2 check valve hidden behind the engine,in the metal piping between the engine and the firewall.The AIR exhaust manifold connection,for bank 2,is a two bolt flange located between cylinders #4 and #6.The bank 1 AIR check valve is right out in the open,behind the alternator.Thanks for your help 2001NBMZ28.
