    There should be a "road draft tube" attached to it, which exits out the bottom of the engine compartment. This is intended to ventilate the crankcase by sucking the fumes out while fresh air goes in through the cap on the oil filler. This was typical of all cars until the PCV system was made standard in the 60s. If you just have a hole in the cover you need the proper tube and maybe the bracket that holds it. I'm sure someone on the list can provide one. I may have one myself.
