I am no expert. Thinking out loud here and not professing.

I am not convinced that the leak has to be below the oil line. After the oil settles from the tank into the case, there may be 7 quarts in there. Look at your case and imagine two gallons poured into it. I can't see it going up really that high.

I think the top oil level in the case is no higher than the viewable part of your leak.
