Dont have a clue as to what a catch can would accomplish. Its certainly no substitute to what a PCV valve is doing.
However A catch can is used when a vacuum pump is added to the crankcase in that capacity the catch can separates the water vapor from the oil. This type of system would only be used in an all out racing application. The one drawback to using a vacuum pump is theres a possibility if the draw is to high oil can be drawn from vital areas such as the piston wrist pins.
