What causes oil to mix with coolant?

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.
