A spun bearing is a serious engine problem that can lead to catastrophic failure. It occurs when the bearing loses its ability to rotate smoothly, causing it to overheat and seize. This can lead to extensive damage to the engine, including the crankshaft, connecting rods, and pistons.
Symptoms of a Spun Bearing
Constant Knocking or Tapping:
* This is usually the first and most noticeable symptom of a spun bearing.
* The noise will be loudest when the engine is under load, such as when accelerating or climbing a hill.
* Source: Car and Driver
Low Oil Pressure:
* A spun bearing can cause a drop in oil pressure, as the bearing is no longer able to maintain proper oil flow.
* This can lead to further damage to the engine, as the components will not be properly lubricated.

Metal Shavings in Oil:
* A spun bearing will produce metal shavings, which can be found in the oil pan or on the oil filter.
* This is a clear sign that the bearing is damaged and needs to be replaced.

Engine Failure:
* In the worst-case scenario, a spun bearing can lead to complete engine failure.
* This can be a very costly repair, as it may require a complete engine rebuild or replacement.
