The thread pitch is M14*1.0 so I'm currently working on either finding a fitting or getting some made to enable a -12 to be used. Indeed it is!
Would you need 2 of these to catch any oil coming from the crank case on a z32? or can you just add y connectors bridging the 2 intake hoses, and bridging the 2 output hoses? Too much hose? :S
Sweet, thought joining the lines together would put something out of balance. Youd only really put on on the cranckcase breather hoses right? and leave the pcv's alone? or could you hook them all up together?
From my understanding crankcase vents to upper plenum pcv's while not boosting, and cam breathers vent to the intake after AFM under boost. Installing the catchcan can eliminate some problems caused by excessive blow by.
When you introduce high boost and or high RPMs to the stock PCV system they can't keep up and you get a lot of oil flying around your intake.
