The Ford Barn - View Single Post - Getting rid or crankcase breather/adapting PCV system

Hi everyone, having had my 54 Customline (312 Y block with 3 speed manual floor change) for just over a month
There is a catch can fitted (taking its feed from the downdraft tube hole!) but I'm going to fit a PCV and blank off the downdraft tube opening.
My question is can I run the output from the PCV via the oil catch can and then into the manifold vacuum (and would there be any benefit)?
