What are the consequences of not repairing engine knocking?

The consequences of not repairing engine knocking: 1. It will shorten the service life of the engine; 2. It will aggravate the wear of components; 3. It will increase engine noise, and may even damage the connecting rod and crankshaft; 4. The engine knocking will cause unstable operation; 5. The engine will vibrate severely, and may cause overheating and black smoke. Solutions for engine knocking: 1. If knocking occurs in a low-temperature environment after the car is started and disappears when the temperature rises, this type of knocking can be temporarily ignored, and the car can continue to be driven; 2. If the knocking sound does not disappear but becomes more obvious when the engine temperature is normal, the owner should avoid high-speed driving, stop and check in time to prevent traffic accidents; 3. If the cylinder is found to be severely out of round, scratched, or the gap between the piston and the cylinder is too large after removing the cylinder head and pulling out the piston, replacement is necessary, including the cylinder sleeve, piston, and piston rings; 4. If the connecting rod is found to be deformed, it should be replaced as much as possible.
Anyone who's driven for decades knows that engine knocking sounds like a ticking noise, and ignoring it can lead to major trouble. It gradually wears down piston rings and cylinder walls, causing severe gas leakage and steadily decreasing engine efficiency. You'll notice a significant increase in fuel consumption, lack of power, and even struggling to climb small hills. Worse yet, the piston may shatter, with debris falling into the engine, damaging the crankshaft and bearings. In the end, you might need a major overhaul or even a new engine, costing tens of thousands—several times more than timely repairs. Plus, it's a serious safety risk; breaking down in a busy area with fast-moving traffic could lead to accidents. My advice: get the fuel quality or ignition system checked at the first sign of unusual noise. Don’t cut corners—delaying repairs will cost you far more in the long run.
