Mini Cooper overheating issue with blown head gasket and water flooding interior on Mini Cooper

Some Mini Cooper owners report experiencing overheating issues due to a blown head gasket, which compromises the seal around the engine and allows hot exhaust fumes or coolant to leak into the cylinders. This can lead to significant engine overheating. Additionally, some owners have noted water flooding the interior of their vehicles, which may not be directly related to the overheating but could stem from leaks in the vehicle's body, windows, or sunroof. Symptoms of a blown head gasket may include overheating, oil contamination in the cooling system, and antifreeze mixing with engine oil. If 'mayonnaise' is found on the oil filler cap or dipstick, it may indicate a head gasket leak. It is crucial for owners to seek prompt repairs for a suspected blown head gasket to prevent further engine damage and to thoroughly investigate any water ingress to protect the vehicle's interior components.
