How Can Coolant Get Into Engine Oil?

Head gasket failure is one of the most prevalent causes of coolant entering the engine oil, and it occurs in nearly every vehicle. This gasket seals the engine block to the cylinder heads and regulates the flow of pressurized coolant and combustion in the cylinders. Because of the high temperatures and tremendous pressures to which this gasket is subjected, it is prone to failure.

It is possible for oil and antifreeze to mix when a car’s head gasket has failed, which can result in a problem. An oil-and-coolant combination can arise from a minor fracture in the oil cooler if the oil cooler is damaged. It is possible that your cooling system will be affected as well.
