Venting the crankcase and the vacuum lines are two different things. The lines on the
Intake are attached to sensors so the computer has info on manifold
Pressure and things like that. Probably not a good idea to unhook those. Has nothing to do with the crank case really.

Manifold pressure reading comes from the MAP sensor.

I've decided to do a 2 port catch can setup. Each port will be vented from the valve covers. I will be using 2 passenger side valve covers, remove the oil fill caps, and replaced with baffled caps to then run to the catch can. Catch can will either be vented to atmosphere or run into exhaust for venturi, I haven't decided that yet. Then I'll connect the valley cover port to each of the two valve cover OEM ports to just help equalize things. Catch can lines will be large -10 lines. Here is a picture to help visualize.
