The oil pump is critical to the mechanical performance of the rest of the engine. Without proper oil circulation, the moving parts of the engine will not work properly. This is why the failure of the oil pump is so important. Help prevent failures by understanding the causes of failures. When your oil pump fails, it may be due to one of the following reasons.


1. Incorrect installation
If your oil pump fails soon after replacement, it may be installed incorrectly. Correct installation can be tricky; from properly homogenizing the pump to creating sufficient clearance in the gears, many small errors in the installation process can cause the pump to malfunction.



2. Bad oil
Whether it is due to poor maintenance or other faults in the engine that cause oil pollution, there are various reasons that cause the oil to deteriorate.

3. Poor maintenance
Yes, changing oil is painful. It seems that you always have to pay the price, and the cost of all these new oils plus filters may increase quickly. However, we cannot overemphasize the importance of oil replacement. Expert Tip: In order to save money, please try to change your own oil.

It is often necessary to change the oil to keep the engine oil fresh. If you have done the oil replacement work yourself, you will know that the color of the engine coming out of the engine is very different from the beautiful and clear oil entering the engine. When the oil circulates throughout the engine, it will absorb a lot of debris from the wear, sludge and other dirt in many moving parts of the engine. All these extras in the oil make it impossible to properly lubricate the parts. The particles in the oil will not provide a barrier to wear, but will cause additional wear on the surrounding parts (especially the oil pump).

In addition, if you just rebuilt the engine, you need to pay special attention to oil replacement. After rebuilding and breaking into the engine, there will be a lot of extra particles floating around. For detailed information about the oil change interval after break-in, please check our blog.

4. Oil pollution
Oil pollution means that anything other than oil enters the oil. In the above example of poor maintenance, the accumulation of debris in the engine oil during its entire time is an example of oil pollution. Similarly, if the engine fails elsewhere and other fluids enter the engine oil, pollution will also occur. For example, your fuel leaks into the engine oil. Contaminated oil can cause great damage to the pump.

5. Low oil
Maybe your oil is very good and free of contaminants. However, if you do not have the right amount of oil in your engine, you will still encounter problems. Each engine requires a certain amount of oil. This specified amount is based on how much oil is needed so that the entire engine is properly circulated and there is enough oil to properly cover all necessary surfaces. If the oil level is too low, the oil pump will have to deal with additional friction due to lack of lubrication. This will cause mechanical failure and warpage of various parts in the pump, which will eventually lead to pump failure.

6. Time and use
The last major cause of oil pump failure is almost all problems. Regardless of the manufacturing quality of the part, it will always be affected by time and use. Everything will not last forever, and eventually your oil pump may disappear due to normal, unavoidable wear and tear. Even if it does not completely fail, it will not achieve the best performance, you need to replace it to restore normal function.
