SYMPTOMS OF A BAD OIL PUMP
1. ENGINE NOISES
One of the first symptoms of a bad oil pump that you’ll probably notice is strange noises when the engine is running.
The most common noise is a whining noise usually produced by the oil pump itself.
You may also hear knocking, subtle grinding, and ticking noises that usually come from the engine having poor lubrication.
These are very similair symptoms to bad crankshaft bearings so the moment you hear these noises, make an inspection of what’s wrong.
2. OIL WARNING LIGHT COMES UP
At first, while the oil pump is still partially working, the oil warning light may come up occasionally and disappear for some time.
This is one of the symptoms of a bad oil pump that should raise the alarm.
Later as the problem gets worse, the warning light may come up as soon as you start the engine or just after the engine’s warmed up.
3. REDUCED ENGINE PERFORMANCE
This is one of the symptoms of a bad oil pump that you’ll easily notice because the car doesn’t go as it used to.
The gas pedal response is sluggish and the car sort of bogs down whenever you want to accelerate.
4. HIGHER ENGINE TEMPERATURE
Besides reduced performance, you may also notice that the engine temperature is always a bit higher than normal.
Poor lubrication will cause this, there is actually no overheating happening, and the car can be driven.
The temperature is just a bit above normal but it’s like that all the time.
CONCLUSION
In the end, remember this: with poor lubrication and bad oil flow the engine will suffer major and expensive damage.
With a bad oil pump, you can sometimes drive longer without repair but know that it can also give in instantly.
So, best not to drive the car until you resolve the problem otherwise there might be major damage due to poor lubrication.
