Oil Pump Failure: What You Need to Know

In machinery, oil pumps help keep the engine running by lubricating an engine’s pistons and bearings. By doing so, the oil can also cool down these components while an engine is in use. However, there are times when the pump might not be doing its job efficiently and leading to extreme problems. Without lubrication, engine parts can become stuck or overheated, which can cause disasters for the machines they are operating in overall.

But how do you know when your pump is faulty? Are there ways to prevent it? As you delve deeper into understanding oil pump failure, you can become more aware of how to maintain yours. While it may be a pain, there may also be times when you have to replace your pumps in general. Industry Nest Parts carries oil pumps straight from their manufacturers to ensure that you never get faulty parts.

What Causes Oil Pumps to Fail?

There are a few common reasons why your pump might go bad:

Low Oil Levels

One of the most apparent occurrences happens whenever the oil levels become too low. In order to keep engines lubricated, the pump needs to be filled considerably with oil that it can pressurize. The less oil there is, the more friction the pump will come into contact with, which can warp its system over time. If this occurs, your pump will continue to have difficulty performing tasks, even after you refill the oil.

Engine Sludge

“Sludge” refers to a combination of dirt, detergents, and old oil. Over time, these components break down and leave behind buildup in different engine parts. This can obstruct oil from pumping through the engine parts, which can cause a pump to overwork itself as it tries to push through the mass. This can then lead to the pump breaking down entirely.

Poor Installation

The only way a pump will perform its job is if it is put into an engine correctly. Otherwise, how is anything supposed to get lubricated? Those placing oil pumps need to ensure that mounting bolts are tightened properly and that the driving components are aligned. While performing this task, it is also crucial to make sure that there are no obstructions or debris in the engine so that the pump can begin working right away.

Signs of Failure

The best way to make sure that your oil pump remains intact is by detecting a problem as soon as it happens. One of the most obvious ways to tell that there is an issue is when an engine light comes on. This light usually indicates that the oil pressure is low, which is often a sign that you need to refill the oil inside.

Another indicator is an increased engine temperature. As the oil is supposed to keep the inner components of the engine cooled down, overheating means that things are not properly lubricated. This is due to the friction caused between parts rubbing against each other.

Noise can also be a cause of concern. If improperly oiled, parts like valves can begin to creak. Not only that, but the oil pump itself may start to make noises if its internal gears are wearing down. This often occurs due to warping or age.


Along with causing friction in your engine, a faulty oil pump can cause issues for the whole machine that the engine is operating in. This is because the engine can totally break down, which affects the rest of a machine’s components. As a domino effect, an out-of-order device can lead to production delays.

Just one small part, like an oil pump, can lead to expensive repairs and replacements since other parts are sure to be ruined. Along with this, the lack of production is also certain to cost companies money, as they won’t be able to ship out or sell as many products as they usually do.

Failure Prevention

Your best bet in making sure that you do not deal with disaster is by making sure you regularly maintain your oil pump. It is not a difficult task to perform and can provide you and your engine with a lot of relief. In general, maintenance should be performed at least once a year, but oil refills will need to be done more frequently.

Whenever inspecting an oil pump, it is crucial to make sure that all of the pumping screws are tightened and free of corrosion. The pipes and hoses within the pump should also be checked for any signs of deterioration, as this can lead to oil leaks and make it more difficult for the pump to work.

Remember also to clean an oil pump’s filters so that they do not become built up with that “sludge” discussed earlier. Reusable filters can be taken out and soaked in soap and water. After it is fully dry, it can be put back in. There are also cleaning kits available that include hoses that can aerate the filters.

Time for a Replacement?

Usually, pumps last the same lifespan as the engine it is working with, but improper care or years of use can begin to impede their performance. In these instances, it can be a better idea to replace the whole pump.
