Which of the following is NOT a symptom of a worn oil pump?

The correct answer is that increased oil pressure is not a symptom of a worn oil pump. When an oil pump is functioning properly, it is responsible for maintaining the correct oil pressure throughout the engine. However, if the oil pump is worn, it generally leads to decreased oil pressure rather than an increase.

Increased oil consumption, excessive engine noise, and reduced oil flow are symptoms more commonly associated with a failing oil pump. A worn oil pump can lead to inadequate lubrication, which can cause the engine to work harder, resulting in excessive noise and potential damage. Additionally, if the oil pump cannot maintain sufficient oil flow, the engine may experience performance issues, further indicating that the oil system is compromised.

Therefore, the correct identification of increased oil pressure as not being a symptom of a worn oil pump reinforces the understanding that a failing pump leads to reduced efficiency and performance in oil circulation, not an increase in pressure.
