COMPRESSION CONDITION
ACTION/DIAGNOSIS
Low compression reading on some cylinders.
(a) Use oil in cylinder to see if rings are worn.
(b) If compression increases, rings and/or cylinder wall are worn.
(c) If compression does not rise, do a cylinder leakage test to
determine source of problem.
high relative compression readings and relatively equal cylinder
readings.
but, if excessive exhaust emissions, lack of power, poor performance,
or poor fuel consumption do a cylinder leakage test to determine source
of problem.
Lower relative compression readings. One or more cylinders lower than
others.
Do a cylinder leakage test to determine source of problem.
4.3.8 When making repeat tests on the same cylinder, variations in the
piston position and engine temperature can cause gauge
readings to differ by up to 10%.
4.3.9 If an engine has multiple faults (such as worn rings and burned
valves), the tester may indicate only the most serious fault.
Note: There is always some leakage past the piston rings. As a result
you will always hear some leakage when listening to the dipstick tube.
