I am pretty sure you have a head gasket that has a crack in it. Coolant is possibly getting into your cylinder/cylinders. Check your radiator level when the car is cold. Check for signs of water in your oil. Usually seen on the dipstick as little droplets. Sometime the oil on the dipstick will look milky, light brown or gray.
With a head gasket you may have cracked a cylinder head or warped a head. Either having the current cylinder head machined flat is very likely also or a new head is a possibility if the current head can not be machined within a specified thickness or height.
I hope I am wrong. But it sure sounds like it to me.
Sorry for the news;
