If the oil is that creamy you may have a head gasket that is blowing coolant into the oil galleys.
There's no way that a properly functioning engine should be picking up enough moisture that the oil gets creamy.
The immediate problem is that creamy oils lose their ability to protect the metal surfaces.
You need to get the cooling system pressure tested.
What leads you to the crankcase ventilation system?
I suppose you could quickly and inexpensively buy a PCV valve....
After running a while does it get more? or less creamy?
