My '54 had parts of a California PCV system on the engine when I bought it. The air cleaner didn't have a hole cut in it for a hose. The angled rubber fitting on the top-rear of the valve cover was pushed into a crude hole. The vent slots on the valve cover were sealed. A question on Stovebolt and got this response from CrankyOldDude. Fun history lesson.

That is pieces of the AC (AC spark plug of General Motors Corporation) “California State Approved” crankcase ventilation system. California required most 1950 and later cars and trucks to be retrofitted with a PVC system when a used vehicle was sold. The program originally started from January 1, 1964 and ran through January 1, 1966.
The installation required two kits, CV3 and KV1002. CV3 consisted of an intake manifold fitting, 3/8 hose, CV609 PCV valve, hose clamps and fitting to the valve cover for an open PVC system. KV1002 closed the system, it consisted of 5/8 inch hose fittings, 5/8 hose to connect air cleaner to the valve cover for clean air induction, sealed oil fill cap and a plug to close up the hole after the road draft tube was removed. The slots on the valve cover were soldered closed.
I believe your PCV valve is a CV693C. If so, it is installed backwards so the flow is backwards. CV693C is designed to mount on the ventilator for the factory installed PVC system on 261 engines as well as California 1960-62 235 engines.
If you want to keep this setup, I would recommend finding a CV609 valve. I would reconnect the open hole on your valve cover with a 5/8 hose to your air cleaner. The CV609 valve is spliced into the hose that connects the valve cover to the manifold fitting. You will need to find some hose fittings, hoses and a CV609 PCV valve.
