Should a Car with a Blown Head Gasket Be Repaired or Sold?
1 Answers
A car with a blown head gasket can be repaired. With the continuous advancement in repair techniques and standards, if the engine receives proper and correct repairs after a blown head gasket, it will not significantly affect the car's usage. Here is some relevant information: 1. Main causes of a blown head gasket: (1) The engine operates at high temperatures for extended periods without adequate cooling, leading to deformation of the engine block due to overheating. (2) During engine assembly, the bolts connecting the cylinder head to the engine block were not tightened to standard specifications. Excessive pressure can then damage the head gasket. (3) Uneven surfaces between the cylinder head and engine block cause uneven pressure distribution on the head gasket, resulting in damage from high-pressure gas. (4) Neglecting regular maintenance, such as failing to check coolant and engine oil levels. Insufficient lubrication and coolant can lead to engine overheating, increased wear, and deformation of the engine block. (5) Long-term aggressive driving causes fluctuating pressure levels within the engine block. 2. Common symptoms of a blown head gasket: (1) Overheating coolant temperature (normal operating temperature is around 90°C). (2) Severe engine shaking accompanied by unusual noises. (3) Rapid consumption of coolant. (4) Engine oil turning into a cloudy, milky yellow color.
