What are the symptoms of a faulty oil pump?

[ArianaRose]

Symptoms of a damaged oil pump are as follows: 1. Weak acceleration, with a braking sensation when accelerating sharply. 2. Difficulty starting, requiring prolonged key turning. 3. Abnormal noises while driving. 4. Illuminated engine warning light. 5. Abnormal engine vibrations. Causes of oil pump damage are as follows: 1. Use of low-quality or incorrect type of engine oil. High-quality oil can appropriately extend maintenance intervals, while inferior oil accelerates engine wear, causing abnormal noises and mechanical damage. 2. Long-term failure to replace the oil filter. A clogged oil filter increases the oil pump's supply pressure, leading to accelerated wear under prolonged high-load conditions. 3. Insufficient oil level. A drop in oil level reduces the oil pump's cooling efficiency, causing severe overheating and damage due to "dry pumping."
