If the OCC fails to achieve 100% efficiency, then it DOES NOT WORK! Personally, if I am paying for a product with my hard earned cash, then those products need to work at 100%. Those BSH units are not cheap...

Unfortunately, the only way to stop crankcase vapors from reaching the intake is to eliminate your PCV system altogether. No oil catch can will stop everything, however, a single perforated aluminum plate sounds a bit ineffective. There are plenty of DIY OCC designs in various forums around the internet. Most use either steel wool or multiple layers of steel mesh (like from a screen door) to provide better oil condensation, but a balance must be struck between OCC effectiveness and PCV flow.
