Re: 1939 Six crankcase ventilation

Your description does not sound at all like any part of the crankcase ventilation system which comprises the road draft tube usually fitted to the rear valve tappet cover for an fume exit and the oil filler cap as the fresh air inlet. What you describe sounds to me like an intake manifold drain tube with a check valve at the bottom. See a concurrent thread on here right now titled "38 120 poor running".

Or provide a picture?
