KraigAP,
Thanks for the link/video - interesting info. I would not say that the catchcan is not needed due to the beefy PCV. My limited (mileage) experience is that oil does indeed collect in the catchcan. IIRC, I found 1 or 2 teaspoons after <1,000 miles of mostly city along with some highway driving.
Run a search for 'catchcan' and you should find some photos of oil collected along with the mileage driven in the collection period. Pretty good info, imo.
HTH.
