Troubleshooting by Measuring
Compression Pressure
Compression pressure drop is one of the major causes of increasing blow-by gas (engine oil contamination or increased engine oil consumption as a resultant phenomenon) or starting failure. The compression pressure is affected by the following factors:
1. Degree of clearance between the piston and cylinder
2. Degree of clearance at the intake I exhaust valve seat
3. Gas leak from the nozzle gasket or cylinder head gasket
The pressure will drop due to increased parts wear. Pressure drop reduces the durability of the engine.
A pressure drop may also be caused by a scratched cylinder or piston, dust entrance from the dirty air cleaner element or a worn or broken piston ring. Measure the compression pressure to determine the condition of the engine.
Compression Pressure Measurement Method
1. Warm up the engine.
2. Stop the engine. Remove the high-pressure fuel injection lines as an assembly from the engine. Remove the fuel injector from the cylinder to be measured. See "Removal of Fuel Injectors" on page 194.
