What causes oil to mix with water?
Water in car – Water condensation in cold air or combustion gases : this phenomenon is extremely rare and only occurs at specific temperatures. Water in the oil – Coolant leak due to non-watertight seal (cylinder head gasket, etc.). If this happens, there is a leak and water is getting into the oil.
Can a bad water pump cause oil in coolant?
Water pumps will not cause oil to enter the cooling system . ... This will make the coolant mix with the oil. The third way that oil can mix with the coolant is when the engine has blown a head gasket. However, if the head gasket is blown, the engine may overheat and have loss of power.
How do I know if my Headgasket is blown?

How do you get oil out of water in your engine?

Does a water pump have oil in it?
All water pumps contain a small hole known as the weep hole. The weep hole provides vital information about the health of the seals inside of your water pump. Two such seals exist: the oil seal and the internal water pump seal.
What happens if coolant mixed with oil?
