Well if it's not going out the over flow and you say the oil is clear,
it's either going into a cylinder(s), out a leak at the heater core,
leak at the water pump or radiator.

Pull the plugs and see if they all look the same, 1-2 nice clean ones
while the rest are dirty would point to a head gasket issue.

Check the drain for the core and see if it shows coolant, Run it until
it gets up to temp and look for a leak. It could be leaking but the
airflow and warm engine are boiling it off and not showing the leak.
