The inner casing goes up into the lower flange and tube assembly. There’s a gasket between that assembly and the block with a passage through it. I’m not 100% sure but it looks to me like that’s the outlet for the cooling passages in the block. Seepage there with a bit of oil coming from the bottom of the crankcase would make a nice ooze.
