Need help perfecting the budget build hemi swap

So my cheap street PCV vapor separator seems to work fine. It should keep all that nasty sludge from building up carbon, on my pistons, and valves.
I was reading on a Camaro forum how this idea wouldn't work, because the petcock valve leaked vacuum, when they attempted to do it. That would be because air running from one side, to the other creates a vacuum,( that's how a paint gun works ) but for this purpose, it's running a vacuum so you'd have to flip the valve over, and it still wouldn't work because, we're not talking about 30 - 65 lbs of negative pressure. So a brass valve would be too heavy. I say... tap that *****, ( I mean ) ampule, install a small male brass fitting, and run a hose to a larger reservoir. ( big enough to add removing the oil from that reserve, part of the oil change maintenance schedule every 3000 miles.
P.S. I don't recommend using the air filter that came with the unit, I think it could impede airflow, and cause crankcase pressure. The factory unit used something very similar to a choreboy copper scouriing pad. I just stuffed one in the ampule. The air would normally come through the inlet into the glass, than up through the filter in the center like an oil filter.
Now I have to re-plumb the carb to the regulator, which isn't there, because it took a dump. I need to plumb Just to under the front of the floor pan. The temporary set up I have, is shady at best, but works for testing.
