To determine if the oil pump is damaged, the following steps can be taken:

 

1. Check the oil pump for dripping. If you find signs of oil or wet stickiness around the oil pump, this could mean that the oil pump seals are damaged or that there is some other leaking problem.

 

2. Check the sound of the oil pump. After starting the engine, listen for unusual noises from the oil pump, such as a harsh buzzing, scraping or knocking sound. This may indicate damaged or dislodged internal parts of the oil pump.

 

3. Observe the oil pressure indicator. There is usually an oil pressure gauge on the dashboard to show engine oil pressure. If the oil pressure indicator shows low oil pressure and there are no obvious mechanical problems with the engine, there may be a problem with the oil pump.

 

4. Check for abnormalities in the normal operation of the engine. If the oil pump is damaged, it may cause the engine to run at high speeds or under heavy loads with a lack of power, poor acceleration or stalling.

 

5. Perform an oil pump pressure test. This involves the use of a specialist automotive service tool, such as an oil pressure gauge, to measure the pressure output of the oil pump under different operating conditions. If the pressure value is below the standard range specified by the manufacturer, then a new oil pump may be required.

 

Please note that the above method is just one of the ways to initially determine if the oil pump is damaged. If you suspect that there is a problem with the oil pump, it is advisable to consult a professional auto mechanic for a detailed inspection and diagnosis.
