The Oil Pumps in the engine draws the lubricating oil from the oil pan and allows the lubricating oil to flow through the fast-moving internal parts. The oil passes through specially designed channels (called oil channels). The role of the engine oil is to cool moving parts and minimize friction. Properly operating high-pressure pump will keep the engine inside alive and operate normally within hundreds of thousands of miles.

Composition and function

Inside the oil pump is a simple combination of gears, bolts, nuts and housing. Because the pump is located in the oil pan filled with lubricating oil, it will hardly rust or corrode the metal casing. High-pressure oil pumps use drive gears to generate pressure in the system. The pressure pulls the oil out of the oil pan at the bottom of the engine, and then clears the oil to the head at the top.


common problem

The engine needs frequent oil changes to prevent the fluid from thickening and clogging the pipeline. When the oil filter becomes bad, it may release dirt and metal debris collected from the engine into the oil pan. If this happens, the high-pressure pump will absorb these contaminants and send them back through the oil channel. When fast moving internal components do not receive the proper amount of oil, these components may overheat or become stuck together. The result is a loss of power or the engine cannot even start.

If the pump draws a lot of contaminants, the teeth on the pump gear may suddenly come off. Broken teeth will reduce the pump's ability to deliver oil through the system, resulting in a sudden lack of fluid. In addition, the teeth may get stuck in the remaining moving gears and stop the pump completely. Once the pump stops working, GM will issue a fault warning to the instrument panel to warn the driver. The engine must be shut down immediately to protect the remaining internal parts from expensive damage.


Don't underestimate the importance of high-pressure oil pumps
The engine requires the oil pump to work properly and provide the correct type of pressure to deliver oil to the entire engine. When the pump fails to operate or the pressure does not reach the optimal level, it may cause major problems to the engine. When the oil pump fails to operate properly, there are some typical signs that need attention.

Like many problems in cars, when the pressure is not high enough, the service engine lights will also light up. I hope you will not fall into the category of drivers that ignore the light and put duck down tape on it. A low pressure alarm may mean that your engine is leaking or burning oil faster than necessary. The reduced pressure means that the oil will not properly lubricate the vehicle. If left unchecked, it may cause problems such as overheating and damage the engine.

The driver must pay attention to the sound and feeling of driving. In many cases, when the oil pump is not working properly, the caregiver will start to make noise, or the vehicle cannot drive smoothly as before-each case is the reason for checking the oil pump. Dodge Cummins is a rugged engine that requires oil pressure high enough to deliver oil to the engine bearings and ensure that the car starts properly. If you find that the crank is starting, and it may be a pressure problem, it is not necessary to have a bad starter.

The importance of high-pressure fuel pumps in engines must not be underestimated. This is an indispensable device and function of the car and is responsible for the normal operation of many important systems. Just like the human body, in an engine, all parts depend on each other to make the entire part function properly. No part can be ignored, especially the high-pressure oil pump. Make sure to always check the engine oil when the engine is aging to ensure that there is no oil leakage due to leakage. These pressure changes will cause greater problems. Because the parts are not properly lubricated and frictional, and heat build-up can erode the parts and act quickly. Therefore, do not underestimate the high-pressure fuel pump in the engine.

Make sure that the engine performance is always maintained and that the oil pressure is tracked at all times.



The oil pump works by circulating oil under pressure to the engine's rotating bearings, sliding pistons and camshafts. Large-capacity fluid bearings can be used to help cool the engine.
