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.
ACTION/DIAGNOSIS
(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.
but, if excessive exhaust emissions, lack of power, poor performance,
or poor fuel consumption do a cylinder leakage test to determine source
of problem.
Do a cylinder leakage test to determine source of problem.
