Should a Slightly Blown Cylinder Head Gasket Be Replaced?

[DiRafael]

A slightly blown cylinder head gasket should be replaced. Because after the cylinder head gasket is blown, it is very likely that water will enter the engine oil, indicating that the gasket has failed. This requires immediate replacement, otherwise excessive temperature may cause cylinder scoring and lead to severe engine damage. The symptoms of a blown cylinder head gasket are: 1. Decreased engine power, resulting in poor vehicle performance; 2. Abnormal high engine temperature and poor operation; 3. Reduced coolant level, presence of engine oil in the coolant, or water in the engine oil. More information about cylinder head gasket failure is as follows: 1. Cylinder head gasket failure refers to an impact-type fault occurring between the engine's piston and the cylinder liner. 2. Engine cylinder head gasket failure can simply be understood as an impact-type fault occurring between the piston and the cylinder liner or the gasket. Common gasket erosion is caused by high-temperature, high-pressure gas impacting the gasket, burning the sealing edges, protective rings, and asbestos board, leading to cylinder leakage and mixing of lubricating oil and coolant.
