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.Know More
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.Learn more in Engine Oil
Topping off the oil in a vehicle to the point that it overflows can cause the additional oil in the oil pump to build pressure on the seal on the rear main bearing. As a result, the pressure on the rear main bearing can burst or rupture, ultimately causing oil to leak from the vehicle.Full Answer >
The time frame for replacing engine oil varies by car, but in general oil should be replaced every 5,000 to 7,500 miles, advises How Stuff Works. Various factors such as the type of vehicle and driving conditions make a difference, so the vehicle's user manual provides the most accurate instructions.Full Answer >
Most cars take between 4 and 5 quarts of engine oil, but some vehicles can take up to 15 quarts of oil. Your car manual should indicate how much engine oil it requires for a full oil change.Full Answer >
If a driver does not check the oil pressure in his vehicle, engine problems, many of them preventable, go unnoticed. The vehicle's oil level should be checked at least once a month to make sure there is enough and that it is not contaminated, according to Dummies.com.Full Answer >
