i think the cream you're finding is typical combustion by product/water vapor in the ambient air condensing and mixing with the oil.
any ICE engine will develop that creamy water vapor in the crank case ventilation system.
now for your missing coolant, if the system isnt able to be sealed and is open to atmosphere then the boiling point will be lower than ideal and isolated boiling will occur in the cylinder heads turning to vapor in the coolant system which could then vent to atmosphere.
do you know the coolant system is getting pressurized and holding?
