Colsed PCV to Open PCV Olds 403

I currently have a Closed PCV system; would it be possible to buy an oil fill cap from an open system, hook that up to the input on the carburator and put a breather on each valve cover; IMO that should work better and it'll be harder for the vacume to suck oil out of the oil fill neck because it's much higher then the valve covers. $.02USD everyone?

This would work well.
Unless you had major blow by, the oil breathers would only vent fumes at or near full throttle.

However, there is nothing wrong with sticking the PCV valve in the valve cover. Most valve covers have little baffles around the PCV vale opening to prevent oil from getting sucked up the tube.

Well the ones I have on there now are the stock ones and don't; the chrome ones I got sitting around do; but I'm not putting those on untill I put my new intake manifold on. Maybe I'm just too bored.
