+ CrankyOldDude - Regarding the PVC valve being installed backwards, are you saying that the airflow through the valve should be from the threaded end to the barbed end, instead of the current barbed to threaded?
Yes, it is backwards. That PCV valve will close up with some manifold vacuum unless it is gummed up or broken. It is the wrong valve for the system.
I would install a road draft tube with a vented oil cap or repair the PCV system. I seen a number of these old 235s with the PCV system partially removed and the engine left un-vented. The engines were all caked up, with stuck pistons rings, clogged oil passages and oil blowing out almost every seal. Tampering with these systems in the early days was common, people thought they would cause engine performance problems. The "State Approved" retro fit kit did look out of place.
The factory PCV systems as seen on 261 engines do show up on E-Bay a few times a year. These were also factory installed on California 1961 and 62 235 engines as well. They do look much better and look like they belong on the engine.
