NOTICE:
The measurement must be done as quickly as possible.
Standard compression pressure:
1400 kPa (14.2 kgf/cm2, 203 psi) or more
Minimum pressure:
980 kPa (9.9 kgf/cm2, 142 psi)
(x) Remove the compression gauge.
(y) Perform the inspection above for each cylinder.
(z) Check the pressure difference between each compression pressure.
Pressure difference:

(aa) If the cylinder compression is low in one or more cylinders, pour a small amount of engine oil into the cylinder with low compression through its spark plug hole. Then inspect the cylinder compression pressure again.
HINT
If adding oil helps boost the compression, it is likely that the piston rings and/or cylinder bore are worn or damaged.
If pressure stays low, a valve may be stuck or seated improperly, or there may be leakage in the gasket.
