Is Engine Cylinder Head Gasket Failure Considered a Major Overhaul?
2 Answers
Engine cylinder head gasket failure is considered a major overhaul. The symptoms of engine cylinder head gasket failure are as follows: 1. Burn-through between two adjacent cylinders: The car lacks power, the engine runs unstable, the engine speed cannot increase accordingly during rapid acceleration, and there is fuel choking in the carburetor, with backfiring from the exhaust pipe. 2. Burn-through between the combustion chamber and the water jacket hole: When the engine is running, opening the radiator cap will cause bubbles to emerge, and in severe cases, water spraying may occur, with water being expelled from the exhaust pipe and emitting large amounts of white smoke. The introduction to engine cylinder head gasket failure is as follows: 1. Introduction one: Engine cylinder head gasket failure refers to the burning and damage of the engine cylinder head gasket, resulting in poor sealing of the engine cylinder or combustion chamber. 2. Introduction two: The cylinder head gasket must be replaced if it is damaged, and whenever the engine cylinder head is removed, the cylinder head gasket must be replaced.
When it comes to engine cylinder burning, it often means a major overhaul is required. With over 20 years of driving experience, I've personally encountered several cases of cylinder burning, which is essentially severe internal overheating of the engine, leading to scratches on the cylinder walls or melting of the piston rings. In such situations, mechanics typically disassemble the engine to inspect core components like the pistons, cylinder liners, and connecting rods. If the damage is minor, it might only require replacing the piston rings or local repairs, which doesn't count as a major overhaul. However, in severe cases, a complete disassembly, grinding, or replacement of parts is necessary, which is considered a typical major overhaul. A major overhaul not only takes one to two weeks but also costs thousands of dollars. For prevention, I believe it's essential to change the oil regularly, monitor the water temperature, and avoid prolonged high-temperature operation of the engine. In summary, cylinder burning is a common issue, and timely inspections can save a lot of trouble later on.
