What would cause oil to leak into coolant?
If the engine overheats the head gasket blows up and causes oil to leak into the coolant system. The engine block typically cracks when the engine lacks proper oiling and cooling due to a heat build-up. When this crack occurs, the oil will start to leak into the coolant.
What happens if you get oil in your coolant?
When a head gasket fails, oil can leak into the cooling passages and then end up in the coolant. This results in the brown sludge that can be seen in the top of the radiator, and the coolant reservoir. Coolant can also leak into the combustion chamber. This will result in a white cloud of sweet smelling exhaust.
