The down draft tube vented the crankcase to atmosphere before closed crankcase venilation systems (PCV) were required. I don’t remember what year closed systems became required but I think it was in the early 60s. The downdraft tube came off the intake manifold and went down to exhaust the gasses under the car.

Don’t think an intake leak is going to cause the kind of problem you have. It may be time to yank it back out and look at the internals.
