I AM DOING THE LS1/LS6 INTAKE SWAP AND THE VALLEY COVER PCV SWAP ALSO. WHILE I HAVE THE MANIFOLD OFF I WILL ALSO BE DOING THE OIL PRESSURE RELOCATION TO FORESTALL OR ELIMINATE ANY POSSIBLE NEED TO REMOVE THE MANIFOLD AGAIN IN THE FUTURE. WHILE THE HOSES ON THE BACK OF THE MANIFOLD LOOK OK, THE VERT HAS 73K ON IT AND LOOKS CAN BE DECEIVING, SO I AM GOING TO REPLACE THOSE AS WELL. CAN ANYONE OFFER ANY OTHER MODS/CHANGES THAT I SHOULD DO WHILE I AM AT IT WHICH WOULD OTHERWISE NECESSITATE REMOVING THE MANIFOLD AT A LATER DATE? THANX FOR YOUR OPINIONS/COMMENTS.
You should change out your passenger side air-check valve. It's located all the way in the back of the intake manifold and it is known to gunk up and go bad pretty quickly.
