5. Crank the engine to remove any foreign material in the cylinders.
6. Insert the compression gauge into the spark plug hole.
7. Depress the accelerator pedal to open the throttle fully.
8. Crank the engine and read the gauge.
Standard value: 1500kpa (15Kg/cm
2
, 218 psi)
Limit: 1400kpa (14Kg/cm
2
, 203 psi)
9. Repeat steps 6 to 8 over all cylinders, ensuring that the pressure differential for each of the cylinders is
within the specified limit.
Limit Max. 100 kpa (1.0 kg/cm
2
, 14 psi): between cylinders
10. If a cylinder's compression or pressure differential is outside the specification, add a small amount of oil
through the spark plug hole, and repeat steps 6 to 9.
1. If the addition of oil makes the compression to rise, it is likely that there may be wear between the piston
ring and cylinder wall
2. If compression remains the same, valve seizure, poor valve seating or a compression leak from the
cylinder head gasket are all possible causes.
Tightening torque
Spark plug: 20-30 Nm (200-300 kg.cm, 14-22 lb.ft)
