I've come to the conclusion I can't properly connect the charcoal canister and oil catch can to a vacuum source without a purge control value. Connecting them straight to the intake manifold applies the most vacuum at idle, which isn't ideal. So for now the catch can and the canister will be vented to the atmosphere. The only question l have left is if the canister serves any value if it's vented or of it's no different from having no canister at all.
