3. Diagnostic & Repair Process
Understanding how an engine compression test is performed and what it signifies is key to appreciating the service.
How are Engine Compression Tests Diagnosed?
An engine compression test is used to determine if one or more of the cylinders in an engine is producing insufficient or low compression. This diagnostic procedure is vital for pinpointing internal engine problems.
* Purpose: A basic engine compression test is performed by allowing the engine to turn over without starting, while other tests may be done while the engine is running. All together, these engine compression tests can help a technician:
* Locate damage to piston rings, pistons, or cylinder walls.
* Identify bent, worn, or stuck intake and exhaust valves.
* Diagnose a deteriorated head gasket.
* Even point to exhaust problems, such as a clogged catalytic converter or muffler.
How are Engine Compression Tests Done?
To perform a compression test, a technician will make sure the oil level is normal and warm up the engine before disabling the ignition and fuel systems. The spark plug wires are disconnected and the spark plugs are removed. A compression tester is installed in one of the spark plug mounting holes. The technician will have someone turn the key to engage the starter for a short time. The gauge on the compression tester reveals the pressure in the cylinder. The technician will record the reading and repeat with the rest of the cylinders. The process is more complex for a test with the vehicle running, but it reveals more information about the condition of the engine.
Our Recommendations for Engine Compression Test Issues
Variations from one vehicle model to the next require access to vehicle-specific information and repair procedures. It is recommended that a qualified technician diagnose and repair symptoms of low compression.
What to Look Out For When Dealing with Engine Compression Test Issues
The ignition system and/or the fuel system need to be disabled prior to performing an engine compression test, unless the test is being done while the engine is running. In the latter case, a professional technician should perform the test. Damage or injury can occur if excess fuel is sprayed from the engine during the procedure.
Can I Replace the Engine Compression Test Myself?
While a basic engine compression test is not too difficult to perform on some vehicles, it is quite a challenge on others. Access to cylinders located at the back of the engine compartment can be minimal. Specific vehicle data must be referenced for comparison to the compression test results. Moreover, an engine compression test alone is usually not enough information to properly diagnose poor engine performance. Other tests need to be conducted for a solid and targeted diagnosis because several conditions can lead to the symptoms associated with compression loss. These tests are usually better left to a professional technician.
* Step-by-Step Procedure (General):
- Warm up the engine to operating temperature.
- Disconnect the ignition system (coil packs or spark plug wires).
- Disable the fuel system (e.g., by pulling the fuel pump fuse or relay).
- Remove all spark plugs.
- Screw the compression tester into one spark plug hole.
- Have an assistant crank the engine for 4-5 seconds.
