Engine compression is the pressure generated by an engine in the cylinders when it is running. A fuel injector uses the mixture of fuel and air into the chamber for ignition. This combustion process provides energy to the engine which in turn provides power to the car to make it move. However, if the engine compression is low, you will start noticing several issues.
If you start noticing engine misfire and low fuel mileage then you must check the car’s engine compression by taking a compression test. In case the compression test results in low engine compression then you need to fix it as soon as possible. Here is how you can fix the low engine compression issue.
Steps to Fix Low Engine Compression
The low combustion engine can be caused due to several mechanical reasons. The common causes of low engine compression include a worn-out timing belt and leakage in valves. Here are the steps of fixing low engine compression:
Confirm If the Engine has low compression
Before you begin to tinker with the engine parts, the first thing to do is use a compression gauge and test to see if there is low compression in your engine. This process will usually take 45 minutes, so make sure you have some free time on your hands. You can take a compression engine test to confirm. Once you confirm the lower compression, it’s time to check the reason behind it. However, it is best to get it tested professionally.
Look For the Cause
Check all the compression parts step by step to find out the reasons for low engine compression. Also, physically examine all the parts such as cylinder, piston, valves and head gasket types to see if any of them are damaged or broken.
Repair or replace the damaged part
Once you find out the damaged part, repair or replace it as soon as possible. You can also repair the part yourself; its location is accessible to you. However, this will be a long and expensive job because it involves removing the engine. Be prepared for it.
It is important to note here that most repairs require professional assistance, thus consider a qualified mechanic if you are not sure about making any repairs.
Take your vehicle for a test drive
Once you repair or replace the damaged part, take your vehicle for a test drive. A test drive is important to ensure that the low engine compression issue is fixed now.
Make sure you keep an eye on the car’s performance and check if there is still any sign that indicates low engine compression. You may repeat the compression test to be sure if everything works fine.
On the contrary, if the symptoms of low engine compression persist, then there might be another issue with your car engine.
Once you fix the issue, also check the engine compression ratio is balanced.
How to know if there is a compression problem
When one of the elements of the engine fails, symptoms develop that allow us to determine the cause. The same goes for compression issues, which typically cause the following problems:
- Smoke will come from the exhaust due to poor combustion
- Loss of power, since the usual energy cannot be generated
- Increased fuel consumption by forcing the engine to work harder to achieve the same performance
- Starting problems or unwanted shutdown of the engine
- Water and coolant consumption
- The greater amount of polluting emissions as a result of poor combustion
Here we conclude our guide on how to fix low engine compression. When you identify that the pressure levels are incorrect and do not reach the proper measurement values, it is necessary to find the root cause of the problem.
If you act in time, the problem can be solved without affecting other parts of the vehicle, thereby reducing possible repair costs. However, if your vehicle needs frequent garage visits due to other issues, then you can buy a well-maintained used car for sale in the UAE.
