I am blowing oil out of the breather tube so I increased the barb size and eliminated a slight droop in the line. I am being told 2 quarts of oil, period. Forget the sight tube and whether it has been clocked or not. Two quarts. I assume the gears pick the oil up and sling it all over the inside of the case like a ring and pinion housing. Anybody with opinions on this?

My understanding is you fill it until it just comes out of the filler hole.
