You may have driven into a lake!!! If not you could have several problems that would cause this type of injury to your engine. When the engine is cold and you start it up do you have air bubbles appearing in your radiator? This could indicate a blown head gasket that is leaking coolant when you shut your engine off and it cools off. Other possible causes are a crack in a head, cylinder liner or block. Did you ever overheat the engine severely? This may have caused a crack in the block or head. Remove the spark plugs after the engine has cooled and observe each cylinder If you are blowing a mist or coolant this would narrow it down to a head gasket or a head. Otherwise, you are f-----. You have a cracked block and you should bale while it didn't cost you to much. Bad JUJU!!!! There is of course the very bizarre water pump issue that allows the impeller to wear a whole in the rear cam cover and leak coolant into the block. Probably no your first choice but I have seen it. The final piece of info I can offer is to BUY A BOOK!! THERE IS SO MUCH INFO AVAILABLE TO YOU IF YOU TAKE THE TIME TO INVESTIGATE!!! Hope I helped you out!! MotorDick

Oil mixing with water in the radiator is often a result of a leaking head gasket. When this gasket fails, it allows oil to enter the coolant system, leading to the oil and water mix. It is important to address this issue promptly as it can cause engine damage and overheating.
Oil and water don't mix because they have different polarities: oil is non-polar and water is polar. This causes them to repel each other due to the difference in charge. Oil floats on top of water because it is less dense.
Water and oil does not mix because water is molecule and oil is made of hydrocarbon chains. Only molecule substances can mix with molecule solutes.
Water is a liquid that does not mix with oil due to differences in polarity and molecular structure. The molecules in water are polar, while the molecules in oil are nonpolar, causing them to repel each other rather than mix.
Oil doesn't mix well with water because they are immiscible liquids. Oil is non-polar, while water is polar. The differing polarities cause them to repel one another, making it difficult for them to mix.
Oil and water do not mix because they are immiscible due to differences in their molecular structures. Water is polar and forms hydrogen bonds, while oil is nonpolar and does not interact with water molecules. This causes them to separate into distinct layers when mixed together.
