What is the pump in a car?
The oil pump of the vehicle is said to be the heart of the lubrication system. It is the one that sucks oil from the pan and circulates the engine oil under pressure to the bearings, pistons, the camshaft, and all the oilways in the engine then back into the pan and the process begins again. This process helps the system to be lubricated ...
How does an oil pump work?
An oil pump works two ways – one is to reduce the friction and second is to help cool down, removing the heat from the bearings, pistons, and camshafts. If your vehicle has a bad oil pump, chances are, your engine will have issues with the lubrication that can result in severe damages.
Why do hydraulic lifters need oil lubrication?
Since the hydraulic lifters use the oil pressure to do its tasks, it will need a sufficient amount of oil lubrication to operate properly and quietly. A bad oil pump can result in a decreased oil pressure and it won’t be able to flow into the hydraulic lifters.
Why does my valve train make a noise?
You will hear the valve train operating with unusual noises or producing a lot of noise as the oil levels continue to decrease because of the bad oil pump. Noisy hydraulic lifters. One of the most important components of the valve train mechanism is the hydraulic lifters.

In rare cases, a bad oil pump will make noise, normally a loud whining or whirring sound that can be heard when a vehicle is idling. As an oil pump's internal gear mechanism deteriorates and wears, the oil pump will make noise as it begins to fail.
What is the role of an oil pump?
Low Oil Pressure. An oil pump is responsible for pressurizing engine oil and pumping it through a vehicle's engine. A bad oil pump loses its ability to adequately pressurize and pump engine oil, resulting in low engine oil pressure.
How does oil flow affect engine temperature?
A bad oil pump can lead to an increase in engine operating temperature by restricting normal engine oil flow, reducing engine oil lubrication and increasing engine friction, which leads to an increase in engine operating temperature.
Why do hydraulic lifters need oil?
An engine's hydraulic lifters, which are an important valve-train component, require adequate oil lubrication to function properly and quietly.
