  12. INSPECT COMPRESSION

    Tech Tips

    If there is a lack of power, excessive oil consumption or poor fuel economy is suspected. Measure the compression pressure.


    1. Warm up and stop the engine.

    2. Remove the glow plugs. Click here

    3. Disconnect the spill control valve connector.

    4. Check the cylinder compression pressure.

      Tech Tips

      Turn the starter before measuring the compression pressure and remove the foreign objects.

    5. B007W4QE01

      Install SST (attachment) to the glow plug hole.

      SST
      09992-00025   ( 09992-00121 )
      Torque:
      13 N*m  { 133 kgf*cm, 10 ft.*lbf }
    6. B007QFDE01

      Connect SST (compression gauge) to the SST (attachment).

      SST
      09992-00025   ( 09992-00211 )

    7. Fully open the throttle valve, and start the engine.

    8. While cranking the engine, measure the compression pressure.

      Tech Tips

      Always use a fully charged battery to obtain engine revolution of 250 rpm or more.

    9. Repeat steps (a) through (d) for each cylinder.

      Note

      This measurement must be done as quickly as possible.

      Compression pressure
      3,138 kPa (32.0 kgf/cm2, 455 psi) or more
      Minimum pressure
      1,961 kPa (20.0 kgf/cm2, 284 psi)
      Difference between each cylinder
      490 kPa (5.0 kgf/cm2, 71 psi) or less

    10. If the cylinder compression in one or more cylinders is low, pour a small amount of engine oil into the cylinder through the glow plug hole and repeat steps (a) through (d) for the cylinder with low compression.


      1. If adding oil helps the compression, the piston rings and/or cylinder bore may be worn or damaged.

      2. If pressure stays low, a valve may be stuck or the seating may be improper, or there may be leakage past the gasket.

    11. Remove the SST.

    12. Reinstall the glow plugs. Click here

    13. Reconnect the spill control valve connector.
