Notes
Test compression pressure at normal operating
temperature.
If the minimum compression pressure is not
reached, test cylinder leaktightness (01-015).
Unscrew all the spark plugs for testing.
Turn crankshaft with starter and compression
pressure recorder.
Warning!
The engines are equipped with an ignition
system with variable ignition characteristics
(EZL).
