Yes, the early 60s QD exhaust hsg I was looking at had a dividing wall that extended much farther down between the exhaust chamber and shift linkage cavity.
The only other thought I had was when I remembered that some newer style engines actually have a very small pinhole towards the top of the intake water tube allowing a fine spray into the exhaust housing. I know the QD has a very short water tube, but perhaps there is a little bleed hole in the aluminum casting that water flows through on top of the water tube. Perhaps Mumbles could try plugging the bottom of the water tube of his 58 QD hsg, then slowly filling the intake water tube from the top of the exhaust housing to see if water leaks out anywhere in between.
