      So I'm converting over to a gasser intake. And I'm wondering if the breather on the valve cover needs to be under vacuum or not. As my gasser manifold has had all the ports cut off and sealed.

      why are you going to a gasser intake? its not going to make your engine anymore powerful, or give you ANY gains for that matter, besides ease of plumbing an intake system..

      this upgrade is more often used on the turbo diesels, to get rid of the pancake manifold..

      the diesel intake/air box actually flows just as good, if not better than a gasser intake, due to the port length and shape..

      the restrictive part of the diesel air box, is actually the intake snorkel..

      so, whats the NEED behind a gasser intake?

      There is no vacuum such as you have with a gas engine. It is just the crankcase vented to the intake, where the air flow pulls it into the engine to be burned during combustion. The later 1.6's had the fitting at the manifold downsized, to prevent engine run-away in teh event of excess blowby. (Oil is fuel to a diesel, remember.) You can just connect it to any pport on the gasser intake, won't matter.

      I just went back up to read your post....all ports removed and sealed. Drill one out, tap some threads and install an appropriate size nipple for the vent hose and you'll be set to go.
