What are the symptoms of a damaged car oil pump?

[DiMakayla]

The symptoms of a damaged car oil pump include the engine making a harsh noise, the engine warning light turning on, the exhaust pipe emitting a large amount of black smoke, the oil pressure gauge showing excessively low pressure, severe engine shaking, and difficulty starting the car, requiring prolonged key turning. The function of the oil pump is to transport oil from the oil pan to various oil passages (cooling effect) and the oil filter (filtering the oil) through pressurization, while also lubricating the cylinders, ensuring the engine operates smoothly and normally. Causes of oil pump damage: using inferior or incorrect type of oil; clogging of the oil filter, leading to increased oil supply pressure from the oil pump; prolonged operation under such high-load conditions can accelerate the deterioration of the oil pump; insufficient oil quantity reducing the cooling effect of the oil pump; severe overheating of the internal circuits in the oil causing damage.
