What causes oil to mix with coolant?
A blown head gasket is a common cause of oil mixing with coolant. This thin sheet of metal sits between the engine block and cylinder head to create an air-tight and liquid-tight seal. In some cases, coolant will enter the oil. In others, oil will enter the coolant.
Can you mix oil and coolant?
Coolant and oil mixing is a bad sign. This is because it usually points towards the failure of an important part in your engine/cooling system. An oil/coolant mixture will quickly travel around your engine, resulting in overheating and increased engine wear over time.

What does oil mixed with coolant look like?
Milky Colour: When antifreeze first gets into the oil pan, it’ll leave an orange, red, green, or brown fluid in the crankcase, depending on the coolant your vehicle utilizes. However, as the engine runs overtime, the coolant and oil will mix, forming a milky liquid.
Why would my oil look milky?
