Oil Pump Failure and What Causes It?

Oil pumps play a vital role in the proper functioning of an engine. They are responsible for supplying lubrication to the engine’s moving parts, ensuring they operate smoothly and efficiently. However, oil pumps can fail due to various reasons, which can result in engine damage and reduced performance. In this guide, we will discuss oil pump failure and what causes it.

Lack of Lubrication

One of the primary causes of oil pump failure is a lack of lubrication. If the oil level is too low or the oil is dirty, it can cause the pump to work harder than necessary, leading to premature wear and tear. Over time, this can cause the pump to fail completely, resulting in engine damage.

Worn or Damaged Oil Pump Gears

The gears inside the oil pump can wear out or become damaged over time, which can cause the pump to stop working properly. This can happen due to excessive use, contaminated oil, or lack of maintenance. If the gears become worn or damaged, the pump may not be able to supply enough oil to the engine, leading to engine damage.

Faulty Pressure Relief Valve

A pressure relief valve is an essential component of an oil pump. It helps to regulate oil pressure by opening and closing as necessary. However, if the valve becomes faulty, it can cause oil pressure to become too high or too low, leading to engine damage. This can happen due to wear and tear, contamination, or improper installation.

Clogged Oil Pump Strainer

The oil pump strainer is responsible for filtering out any debris or contaminants from the oil before it enters the pump. However, if the strainer becomes clogged, it can restrict the flow of oil to the pump, causing it to fail. This can happen due to dirty or contaminated oil, lack of maintenance, or improper installation.

Broken Drive Shaft

The oil pump is driven by a shaft that connects to the engine. If the drive shaft becomes broken or damaged, it can cause the pump to stop working. This can happen due to excessive use, wear and tear, or improper installation.

Incorrect Oil Viscosity

Using the wrong type of oil or oil viscosity can cause the pump to fail. If the oil is too thick, it can cause the pump to work harder than necessary, leading to premature wear and tear. If the oil is too thin, it may not provide enough lubrication to the engine’s moving parts, leading to engine damage.

Faulty Oil Pump Seals

The oil pump seals are responsible for preventing oil from leaking out of the pump. If the seals become faulty or worn, it can cause oil to leak out of the pump, reducing oil pressure and causing engine damage. This can happen due to wear and tear, contamination, or improper installation.

Contaminated Oil

Contaminated oil can cause oil pump failure. If the oil is contaminated with dirt, debris, or other contaminants, it can cause the pump to become clogged, reducing oil pressure and causing engine damage. This can happen due to lack of maintenance, using dirty oil, or improper installation.

Overheating

Overheating can cause oil pump failure. If the engine overheats, it can cause the oil to break down and lose its lubricating properties. This can cause the pump to work harder than necessary, leading to premature wear and tear and eventual failure. Overheating can happen due to lack of maintenance, driving in extreme conditions, or using the wrong type of coolant.

Improper Installation

Finally, improper installation can cause oil pump failure. If the pump is not installed correctly, it can cause leaks, reduce oil pressure, and eventually cause the pump to fail. This can happen due to lack of experience,
