Diff oil out the vent, why?

My understanding is the hump vent tends to "leak" from slung oil, so they moved it to above the axle on the tube.

Mine is a hump style and an old used breather but I have not had any issues.

85w-90 Amsoil gear lube.

3:23 gears.

I wonder if the ratio increases the slinging effect.

Makes sense, I may try to put a hose on it like a 4-wheel drive truck for now. I don't want to pull the whole rear housing if I don't have to. RMS suspension and Wilwood brakes.
