I dont think there are too many people with failing rear check valves. Its pretty simple after all. Either the rear pcv will be completely plugged or there will be no putting sound. I'm no expert, but I think a catch can eliminates the front and rear check valves completely.
I'm not an expert either but I know mine has a small leak because oil drips from it.
