I wouldn't think that you should any significant net pressure in the Catch Can as there is a big "hoover" at the end of the air intake pipe sucking everything away.
Suggests a significant restriction to air/vapour movement through the catch can.
Ultimately the diameter of any plumbing away from the rocker cover opening should be as big (if not slightly larger) and if your doing a long hose run, you should up-size any tubing to minimize flow restriction.
Don't let the b'strds get you down!!
