Engine Serial Number Decode and Crankcase Ventilation

'62s without PCV didn't have the setup you advocate, they had road draft tubes that routed the crankcase fumes under the car. And yes, even an engine in good shape is going to produce crankcase fumes.

I don't think "Just halfass it" is good advice in any circumstances, but if the original poster wants a quick 'n' dirty get-by fix, oilproof hose can be run from the crankcase breather nipple down to under the car, the PCV valve can be plugged off, and the sealed oil cap can be replaced by an open breather cap (PCV or no PCV, the crankcase needs an air inlet and an air outlet—your "just leave the breather open and call it good" idea lacks an air inlet),
