Should a Car with a Blown Head Gasket Be Repaired or Sold?
1 Answers
If only the head gasket is damaged, simply replacing it will suffice. However, if there are issues with the cylinder liner and pistons, a major overhaul will be necessary. More details about a blown head gasket are as follows: 1. Main causes of a blown head gasket in an engine: (1) Prolonged high-temperature operation of the engine without adequate cooling, leading to deformation of the engine block due to excessive heat. (2) During engine assembly, if the bolts connecting the cylinder head to the engine block are not tightened to the specified standard, high pressure can cause the head gasket to blow. (3) Uneven surfaces between the cylinder head and the engine block result in uneven pressure on the head gasket, causing damage from high-pressure gas. (4) Neglecting regular maintenance, such as failing to monitor coolant and engine oil levels. Insufficient lubrication and coolant can lead to high temperatures and increased wear, deforming the engine block. (5) Long-term aggressive driving causes fluctuating pressure levels within the cylinder block. 2. Common symptoms of a blown head gasket: (1) Overheating of the coolant (normal operating temperature is around 90 degrees Celsius). (2) Severe engine shaking accompanied by unusual noises. (3) Rapid consumption of coolant. (4) Engine oil turning into a cloudy, milky yellow color.
