What about PCV hook-up?

....woops I forgot some info. It's a small block Chevy in a '32 Ford, no power brakes. Or should I use one anyway??? Do you need any more info??? What does a PVC valve do??? Thanks Bill

PCV Positive crankcase ventilation It relieves the pressure in the crankcase.

Thanks, Denny, I knew someone could explain it better than I could.

.....ok, by looking at your diagram Denny on one side I want an oil fill & on the other side a pvc valve. The tube from the PVC valve goes to the carburator??? Right??? Thanks, Bill
