That is what led me to understanding blow-by crankcase pressure. I then bought a simple pcv valve from NAPA attached a hose to it and connected it to the vaccuum input beneath the carb (initially for the windshield wipers, now electric). That was a few days ago. So I do not know if I have done the right thing yet. Too soon to tell. However, I have read everything on the internet about pcv oil catch cans and I am looking to install one between the pcv valve and the intake manifold hose input. Must I have a special pcv valve or is the universal one sold at NAPA OK. Is there enough vaccuum to pull thru the oil separator. I really need all the suggestions I can get. Many thanks. Peter

Seeing you have elec. wipers, the old vacuum source works well.
I had the same setup until I went to a 4bbl. carb.
The PCV valve goes into the top road draft tube hole in the intake manifold. (with suitable rubber grommet etc,)
There is adequate vacuum to operate the system.
The PCV valve should be something that was meant to fit an engine close to the same c.i. displacement as our car.
Oil separators, catch cans?? Should not have to use either.
