YES WE KNOW WHAT IT IS!!!!
Creamy oil means water in the oil, which means cracked something, i.e. Gasket or head or block or intake. Take it to a mechanic and get the oil changed and the old oil analyzed QUICKLY! The longer it runs with water in the oil, the faster the motor will burn up. It's not something you want to mess with. You shouldn't really start it at all until you get it diagnosed.
Sorry Dude! you have troubles now. Good Luck
