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.
