Crankcase ventilation 140-160 1969

This response is to the best of my understanding/recollection, so YMMV.

The hose to the oil filler cap is an INTAKE. Air is taken in to replace the gasses expelled out the oil seperator/trap. As an intake, it needs clean intake air. Therefore, the filler cap should be connected to filtered air, i.e. after the air filter, before the carb.

The hose connected to the oil seperator is an EXHAUST. The trap catches the liquids, and the gasses are sent back to the intake to be re-burned. It should connect AFTER the carb(s) - i.e. into the intake manifold.

This is all emissions control stuff. Prior to 1968(?) the oil seperator vented to the outside air, and outside air was sucked into the engine.

I think you have the hoses backwards.
