You may believe it or not, but the laws of physics don't change for your beliefs whistling

You do realize that the oil "leaking" from those gaping side-clearances had to come from the oil passage in the journal, pass through the much smaller bearing clearance, then exit via the side clearance? It's a series circuit and the vast majority of the resistance (to fluid flow, just as with electricity) comes from the most restrictive part which is the bearing clearance... shruggy
