Have 07 Impreza. with jdm block.and usdm intake manifold.The jdm block has a tube in top of block where the usdm manifolds pcv would normally screw in.. How do I connect  the pcv with this setup?

I used a piece of 3/4" rubber hose and put in a brass threaded bushing that would accept the PCV valve.  Put a hose clamp on either end (on on the tube and one on the bushing end).  The other end of the hose went to the tube on the JDM block.

Where do you connect the vacuum hose that goes to the front of air box. There is no connection in top of jdm block? 

screw the PCV valve into that bushing and then connect the hose to the Intake Manifold.  Mine didn't have a connection to the airbox.  You could get a Y fitting at a parts store to connect it if needed
