does anyone know how to remove the pcv on h22's?

im trying to make something similar to a catch can. so if i remove the pcv, do i need to find a fitting that you could thread into that hole, like a 90 degree elbow? i also heard about adding vents? just drill holes and adding fittings but where and what type of fittings?

 

i think im going to do this... can anyone tell me if this works...
1. plug the nipple the pcv conects to from the valve cover, screw a fitting in there and a add a hose aimmed down and out of the car

2. add 2 vents on the valve cover, screw in fittings and just leave them like that and let them flow into the atmosphere

 

i heard if i did this it'll just squirt out strait up oil and not vapors? and does anyone know anything about the "black box" i have to take out or plug up for this to work?
