it's a closed system in that the intake is inside of the intake plenum and is regulated by the diaphram so that the motor doesn't suck lotsa oil during high vacuum (but it does anyway due to the shitty design) when the diaphram fails it can ether suck oil directly from the crank case or suck outside air, or both

I understand the concept, i think. you're trying to relieve crankcase gases produced during combustion and the PVC plate regulates how they flow into the intake, correct?
