Q:

What are the symptoms of a bad oil pump?

A:

Quick Answer

The symptoms of a bad oil pump are many, and some of them include abnormally noisy hydraulic lifters, valve train noise, a higher operating temperature in the engine, a decrease in the oil pressure of the car and a noise in the oil pump. An oil pump is one of the components of a car that does not require frequent servicing and repairs, but when it fails, it can cause catastrophic impact on the performance of the car.

Full Answer

The oil pump pressurizes oil in the engine and moves it through the engine using this pressure. The oil keeps all the components of the engine lubricated, making them easily movable. A bad oil pump, however, will lead to a decrease in the oil pressure, and this will be indicated by the car's oil indication light. When the normal oil flow to the engine is restricted, friction occurs leading to higher operating temperatures of the engine.

A decrease in the amount of pressure and oil from the oil pump causes the hydraulic lifters of the engine to receive less oil, which makes them produce a lot of noise. The valve train, which includes components such as the valve guides, seals and push rods, requires adequate oil to function properly. So, when the oil supply to the valve train decreases, it can produce a lot of noise.

  • Q:

    What causes the oil light to turn on?

    A:

    The oil light will turn on when the engine does not have enough oil pressure. There is a pressure sensor located inside the engine block. When the sensor notices a drop in pressure, the oil light will turn on to notify the driver.
