COMPRESSION PRESSURE

• If compression pressure is below minimum value, check valve clearances and parts associated with

combustion chamber (Valve, valve seat, piston, piston ring, cylinder bore, cylinder head, cylinder head
gasket). After the checking, measure the compression pressure again.

• If some cylinder has low compression pressure, pour small amount of engine oil into the spark plug hole

of the cylinder to re-check it for compression.

- If the added engine oil improves the compression, piston rings may be worn out or damaged. Check pis-

ton rings and replace if necessary.

- If the compression pressure remains at low level despite the addition of engine oil, valves may be mal-

functioning. Check valves for damage. Replace valve or valve seat accordingly.

• If two adjacent cylinders have respectively low compression pressure and their compression remains

low even after the addition of engine oil, cylinder head gasket is leaking. In such a case, replace cylinder
head gasket.

9.

After inspection is completed, install removed parts.

10. Start the engine, and confirm that the engine runs smoothly. 

11. Perform trouble diagnosis. If DTC appears, erase it. Refer to 

EC-781, "Description"
