What Causes a Blown Cylinder Head Gasket?

[TravisMarie]

The reason for a blown cylinder head gasket is due to the gasket experiencing burning or erosion failure. I. Symptoms of a blown cylinder head gasket: 1. The radiator may backflow with bubbling, the coolant temperature rises, and white smoke appears from the exhaust. 2. The engine oil may emulsify and turn white, or partially enter the combustion chamber, resulting in blue smoke from the exhaust. 3. The vehicle may experience noticeable engine power loss, reduced acceleration performance, and in severe cases, knocking sounds from the cylinders. II. Causes of cylinder head gasket burning or erosion: 1. High engine load, where extreme heat and pressure in the cylinders impact and erode the gasket. 2. Poor-quality gasket material, burnt sealing edges, or uneven wrapping of asbestos sheets and retaining rings, leading to cylinder leakage. 3. Poor driving habits, such as frequently flooring the accelerator or aggressive acceleration, causing excessive cylinder pressure.
