The oil filler ran into the intake tube and I just happened to have a Buick 3.8 sitting on the shop floor and its lower radiator hose was the perfect size to fit the filler tube! It had a ~45 degree bend in it and it worked perfectly. We rarely get this lucky cobbling stuff together! The hose specs say it's 1 9/32" diameter and it should be a Gates 22373.
