i was told that all a pcv is used for is to let the engine vent. well the set up i want to do is this: use a oil cap on one valve cover and a breather cap on the other cover is this set-up ok?

No! It will not pass emissions test!

Nope, not the same thing. PCV valves meter a measured (PCV valve) amount of intake manifold vacuum into the valve cover or crankcase. Its a closed end vacuum. It removes piston ring blow-by and moisture.
The the early days, PVC valves there plugged into a grommet an in a valve cover. The opposite valve cover had a grommet with inlet breathing source by means of a vent tube into the base of the air cleaner. Open ended if you will. Street carburetors are metered to work with PVC valves. I'm not sure of your car registering and inspection state but your car would not pass "emissions impossible" without a proper working PVC system. Believe it or not your crankcase runs cleaner especially in the winter with a PVC valve.

yes that's what I'm running on my Chevy right now,its a lot better to have a pcv valve,but you can run it like this,as long as the engine can breath its ok,older cars didn't have these and they did alright,i would run one on it though,but its not a have to case,it will work like your going to do it,good luck with it.

if your car has a PCV valve I would stick with it as I think you will run into problems blowing seals if you don't.

Nope then you have a vacuum leak and soon to follow, stalling and performance problems.
