Here's an illustration of a closed PCV system; it is identical to that provided to me by the BAR referee.

anyone find a solution for this? I have a ported intake for the pcv valve to hook up, but I still failed. They said it needs to be closed. So i need to remove the vent on the other valve cover and run a hose somewhere to the carbs? Can you just plug off that vent?

You cannot plug off the vent.

Crankcase pressure will skyrocket positive or negative on acceleration or deceleration respectively.

Run the largest i/d hose you can fit to the closest carb aircleaner base.

Ideally, one hose per aircleaner:

-10 to junction block to 4 x -6 to carb air cleaner bases.

Sorry, but I cannot envision this on a Weber setup.
Those air cleaners don't have 'bases'.

Any other ideas?

You gotta go over to the FFR site and pose the question on their So. Cal. forum. Somebody over there has had to get webers through the sb100 process.

If all else fails, just put on a 4 barrel and get it through the BAR and then switch to Webbers.

Just what I said back in Post #7.

Given what Igofastr mentioned above, the 4-bbl has to the best solution for passing through the SB100/SPCNS process. Will save you time, anguish and headaches.
