Description
Common Failure on Oil Pump
The failing of an oil pump could cause serious damage to a vehicle, most especially if the driver did not know its failure symptoms. Well, drivers are notified when a problem occurs in the engine, oil light indicator on the car’s dashboard turned on which alert there is a problem. Below are the failure symptoms of an oil pump:
Low oil pressure: faulty or worn oil pump won’t be able to properly pump oil through the system. This will result in low oil pressure and could cause damage to the engine. although there are several symptoms of low oil pressure which is stated earlier in this pose.
Increased in engine working temperature: oil act as a cooling agent in a vehicle’s engine as it reduces friction. The engine will be at normal temperature when the pump is in good condition as the flow of oil is constant. But, when the flow of the engine oil is slow or stop, the parts are continued to be lubricated by hot oil which is not allowed to flow.
Noise: hydraulic lifter in a vehicle begins to make noise if not properly lubricated. When the oil pump is in good condition and oil is properly circulated these tend to be silent. The lifters are extremely expensive to be replaced which is why it’s important engine never lack oil.
A note on oil pressure
It is important to note that oil pressure is not produced by the oil pump. The oil pressure is caused by restrictions to the flow of oil - through narrow passageways, jet nozzles, and tight bearing clearances. If we simply connected a pipe to the outlet side of the oil pump and allowed it to discharge back into the sump, then there would be no oil pressure - the oil could flow unrestricted.
Knowing this, it’s now clear why worn bearings (particularly main bearings) would lead to a loss of oil pressure: the clearance in these bearings is now larger, and the oil’s flow is less restricted.
