    710 n valve

    does any one have a picture of a 710 n valve in an aby to show its correct fitment?

    In the interim before an ABY photo is posted, go to the link below and click on the "By-pass Valve" label (live link that probably has your answer):

      The pipe which is at 90 degrees to the vac nipple goes to the Turbo to IC hose, the one coming from the bottom of the turbo. (opposite way to what you would expect if it were a dump valve) The pipe opposite the vacuum nipple goes back up to the MAF hose.

        As shown here for an AAN (similar for an ABY or ADU)
