Boxer rocker cover/pcv valve... Catch can also?

Does the rocker cover also contain an oil catch can/strainer as well as the pvc valve/diaphragm?

Also, can the actual pcv diaphragm be replaced on its own? (the round cap on covering this part doesn't seem to be removable??), instead of replacing the whole rocker cover?

Hey, did you find out the answer to this? thanks
