I was looking at a Ford Marine application engine that had the breather caps in the valve covers the same design as some Studebaker models. The engine was carbureted with dual Eldebrocks. The crankcase ventilation system was a line attached from the breather caps directly into the exhaust headers creating a venturi/vacuum effect. I guess a draft tube would not be effective and he did not want to introduce any crankcase gasses back in to the engine. It appeared to be very effective.
