The '57 T-Bird Y blocks had an open crankcase due to the fact that they were pre '63, that being the year that PCV's became mandatory on all new vehicles.

Being discussed is mid-late fifties CA required systems, which was an add-on, not OEM and completely different in design.
PCV became a requirement for the CA 1961 model run and FED for the 1963 model run. Not all non-CA cars received PCV, only in areas that local emission law required it.
ATTACHED is an ILL of proper 4V PCV INSTALL -
