phishy75 Posted December 14, 2004 Share Posted December 14, 2004 ... what the air suction valve (or so it is called in the haynes manual) is and/or does. It is the ~1" diameter hard tube coming off of the head right at the exhaust manifold. I think I'm getting some fluid coming down there. No idea how or why, but I pulled the exhaust pipe off as soon as it cooled down and there is a wet patch right where that tube ties into the head. cheers Link to comment Share on other sites More sharing options...
Numbchux Posted December 14, 2004 Share Posted December 14, 2004 it puts fresh air into the exhaust to make the cat more efficient, my cat's rotten, so I disabled mine, I disconnected, and plugged everything going into them. Link to comment Share on other sites More sharing options...
