What’s the sign of a Bad Oil Pump?
If your oil pump has the following situation, may be you should chang it.
Low Oil Pressure
* The most obvious sign of a bad oil pump is a low engine oil pressure reading. A bad oil pump loses its ability to pump and pressurize motor oil throughout a car’s engine, a condition that can read as a low oil pressure reading on an oil pressure gauge.
Engine Overheating
* Adequate engine oil flow is critical for maintaining proper engine operating temperature. A bad oil pump diminishes both oil flow and pressure, both of which impedes engine oil flow and can increase an engine’s operating temperature.
Engine Lifter Noise
* Engine hydraulic lifters require adequate oil lubrication in order to function properly. A bad oil pump can cause hydraulic lifter noise by reducing the amount of oil lubrication that flows to these critical engine valve-train components.
Engine Valve Noise
* Just as hydraulic lifters require adequate oil lubrication to function properly, engine valves require adequate engine oil flow in order to work properly and quietly. A bad oil pump can lead to noisy valves by limiting the amount of oil flow to an engine’s valve-train.
Excessive Engine Wear
* One of the main jobs of circulating engine oil is to reduce friction within a car’s engine. A bad oil pump reduces engine oil flow and pressure throughout an engine, a condition that leads to increased engine friction and increased engine wear.
