Yes, that helps.   I'll have to try to order that part.    

How did you deal with the clamps?   Cut them off and replace them with screw types?

    Sometimes I can hear a small air leak when under boost.   I think it is coming from the crankcase breather to intake manifold connection or the check-valve.   
    In the Bentley diagram (link below) this is the area of items 5, 6 and 7.
    4 - Evaporative Emission (EVAP) canister purge regulator valve -N80- 
    5 - To connection on intake manifold, lower Throttle Body (TB) flange 
    6 - Check-valve 
    7 - To crankcase housing breather 

  #5... the rubber "T" is usually the culprit.  I've replaced my own, and a couple on other folks cars.  And no... it isn't too fun to get at... and the part is typically not easy to find.
