Mike104 Posted April 3, 2018 Share Posted April 3, 2018 (edited) 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.

steve56 Posted April 3, 2018 Author Share Posted April 3, 2018 Where do you connect the vacuum hose that goes to the front of air box. There is no connection in top of jdm block? Quote Link to comment Share on other sites More sharing options...
Mike104 Posted April 3, 2018 Share Posted April 3, 2018 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 Quote Link to comment Share on other sites More sharing options...
