What would be a typical symptom of a failing oil pump?

A typical symptom of a failing oil pump is low oil pressure readings. The oil pump is responsible for circulating engine oil throughout the engine to lubricate moving parts, cool the engine, and maintain proper oil pressure levels. If the oil pump begins to fail, it may not be able to generate sufficient pressure, leading to reduced oil flow. This can be indicated by a warning light on the dashboard or a gauge that shows low oil pressure.

When oil pressure is low, it can result in increased wear and tear on engine components due to inadequate lubrication, which can lead to severe engine damage if not addressed promptly. The correlation between a failing oil pump and low oil pressure is well recognized within automotive service, making this a critical condition for vehicle operation.

The other options do not typically correlate with oil pump failure. Excessive back pressure is unrelated to the oil pump's function, while decreased engine temperature suggests effective cooling rather than a pump issue. Similarly, easier starting of the engine is not a direct feature of oil pump performance; it could be influenced by various other conditions such as battery state or fuel system health.
