Thanks for all the advice. It looks like I've got to split the cases on this motor after all to see what is going on inside. I'm wondering if there is a bearing seal, is there a rotary vent, and what's the deal with these 3 small holes that are too low. Assuming I can do it, if possible, I'd like to run the rotary vent, and run the vent pipe through the proper vent in the bottom of the engine, get rid of the "steampunk" fitting. I don't think I can really find out what is going on without splitting the cases.
