Ok so when I originally put my swap together I plumbed my catch can like this:

This is the way that I have seen most people run it, but after a summer of driving I have seen pretty much NO excess oil built up in the can.

As of lately I came across someone running their catch can like this:

Which makes sense since it is running off of the PCV valve.

SO, what is the correct way of plumbing a catch can on an S14 SR20 motor? And why?
