A Couple Questions about the Diverter Valve
 

I just sent my ECU out to be flashed. I have a couple questions about the DV.

1.) I was told that the 710N was the Diverter valve to use - I pulled mine out tonight and the last digits of the part number are 710 ... However no N ... When you look into the DV in the hole that is opposite the vacume port - There is an orange nipple http://www.vwforum.com/forums/images...s/icon_lol.gif - http://www.vwforum.com/forums/images...on_biggrin.gif (sorry - couldn't resist!) ... Is this a 710N? The spring pressure is tight and sorta hurts the finger to push it open.

2.) Now that I have this little bad boy off ... Does the return line have to go back into the intake system or can I just let her dump into the atmosphere ...

Many thanks! I have done many modifications on RX-7's - This is my first German car - Its been great and I am really looking forward to having the chip!
