Just about the only places the oil system can suck air is at the o-ring at the pick-up tube where it meets the oil pump, or possibly at the pump itself where it mounts up to the engine block.

- That or someone has significantly over-filled the oil system, and it is getting sloshed around by the connecting rods/crank as the engine runs.
