how is the crankcase ventilated if no pcv valve?
Don’t know about the OP’s, but some cars used a “draft tube”. They worked “OK” when the car was moving at a good clip, as long as unhealthy air to breathe was not a concern.
But at low speeds, or in traffic, the passenger compartment was very stinky. And the engine bay was an oily mess.
Other than those difficulties, they were fine.

I had a factory draft tube on my 1965 Ford Mustang K code. I really wanted to keep the car as original as possible, but the thing was too nasty to endure, and made cleaning the engine a frequent chore. So I put the factory ‘66 PCV system on and lived happily ever after
