    quote Chris_P:

    My guess would be a poor seat where the spaghetti seal abuts the bearing. Maybe cut too short, sealer dried up, etc…, and it is running up between the halves?

    OLCAH, can you see where the leak is coming from?

    This is the type of situation that might be exposed by trying to pressurize the crankcase (with piston covering ports). Although I would think that you will see bubbles around the outside of the bearing normally, because there is no oring there.
