Take a look at the side of a rotor.  There is a groove (outside of the outer
oil seal groove) which channels any blow-by back to the side intake ports.
The blow-by never reaches the crank case which is why the rotary keeps it's
oil so clean looking.  Mine looks quite fresh at 70 hours when I change it.

OK great. No need for PCV. Thanks Tracy.

No! Just vent the sump overboard or into an air oil separator.

BTW when you fill the side ports with JB Weld leave a little depression
so the side seals can equalize the pressure on both sides of the
rotor when they pass over the old side intake ports. Tip I got
from Jim Mederer.
