Steam is caused by burning coolant/antifreeze.
An easy tip:
Black smoke = burning fuel
Blue smoke = buring oil
White Smoke = burning coolant
What happens is that when your car is driven, your coolant goes all throgh your block and back up through the heads to the thermostat and then back to the radiator. When it is transferring in the block, it is trickeling over to your cylinders and getting down to where your oil is to mix to get that chocolate milkish color. If you have been driving this car with the gasket blown, I would check the heads and block to be sure they aren't cracked. Water in oil is extremely bad for the bearings. I would get that oil out of there fast. And about your oil leak, it is probably mixing with your coolant as well if you don't see it dripping on the ground. Check your radiator and coolant and overflow tank if you have one. If it's still green, you are good. If not green, pretty bad. I would get that flushed out of there and replace the head gasket and check the heads and block for cracks and warpage around the same time. This really isn't the best of things for a car. It is really bad.
So the steam means coolant is being burned. Which is caused by getting into your cylinders. I would get these problems checked out before your motor is a complete lose. Hopefully your cylinder wall(s) don't have a crack. It's always a possibily the block could be cracked especially since the car was driven while the coolant was with the oil. Man, hopefully you solve this. Best of luck!
