I would suggest returning the PCV system to stock. Anything else is just a pointless hassle and a waste of time and money.
Agreed. Put the PCV system back in order:
- run a hose from the inlet tube (post MAF) to the driver's side valve cover
- run a line from the passenger side valve cover PCV port to the catch can
- put the PCV valve inline with a hose from the catch can to the intake manifold (after the throttle plate)
You want positive ventilation which means using a vacuum source but you need a PCV valve to ensure you're vacuuming the crankcase only under the right circumstances.
Why does the nitrous have to come off?
The port could be used as a PCV port I think. What is its dimensions? Is there enough flow at that port under engine vacuum to achieve proper ventilation?
Could you remove the plenum and have a 3/8" (e.g.) bung TIG welded by a talented welder on the rear face?

Not sure of the state laws where you are at but a Breather any where on your Pvc system would make it the system open and would not pass NC inspection. Venting gases is a no-no.
