of oil into the cylinder being measured.
Measure compression again. If there is a
higher reading than before (without oil), the
piston rings may be worn or damaged. If the
pressure remains the same after measuring
with the oil, one or both rings and valves
may be the source of the problem.
7. Check both cylinders. Compression pressure
should not vary more than the specified
value from one cylinder to the other.
Difference between each cylinder:
Less than 98 kPa (1.0 kg/cm
