As i was installing the plenum today, a problem came up, i have a R34 GTT, so i bought the AAC from a R33, a Q45 TB, and went to install them, BUT, i can't find nowhere what to do with the line that comes from the back of the valley cover(the one behind the cam gears), i believe that water runs through it but i am not sure what to do with it... Please someone help me...
