Can overfilling oil blow a head gasket? - 2013 Chevrolet Cruze

While overfilling oil is generally not recommended, it usually does not cause a blown head gasket. A blown head gasket is typically the result of overheating, which can occur for several reasons such as a faulty cooling system or low coolant levels. Overfilling oil can strain the oil seals, potentially leading to leaks or reduced engine performance. However, it's highly unlikely to directly cause the failure of a head gasket.
