    Strange sound

    I am getting a strange sound from part of the emissions system, kind of a pffftt/buzzing sound, Coming from a valve on one of the main lines. ANy one know why or what this could be? I will get a pic of the piece if needed.

    Which main line? The arrangement over there on the passenger side fender? Thats the diverter valve. Probably just bleeding off air. That, or maybe one of your one-way valves for either the cats or the head air pipes is going bad and its venting a little exhaust through the diverter.

      Are those valves easily replacable?
