Checking Valve Timing - without Marks on the Cylinder Head Cover
TIP:
The combination of the shown :T40263 , : T40314 and 24 mm socket are better suited than the :T10355 for positioning the vibration damper.
-- Turn the vibration damper in the "TDC" position.
- The marks applied to the cylinder head cover -arrows- must align with the marks on the chain sprockets -1-.
- The notch on the vibration damper must align with the marking on the lower timing chain cover -2-.
If the self-made markings are no longer visible, check the valve timing. Refer to VALVE TIMING, CHECKING .
Continued for All Engines:
-- Install the vacuum pump. Refer to VACUUM PUMP, REMOVING AND INSTALLING .
-- Install the high pressure pump. Refer to HIGH PRESSURE PUMP, REMOVING AND INSTALLING .
-- Install the oil separator.
-- Install the ignition coils with power output stages. Refer to IGNITION COILS WITH POWER OUTPUT STAGES, REMOVING AND INSTALLING .
-- Install the upper timing chain cover. Refer to UPPER TIMING CHAIN COVER, REMOVING AND INSTALLING .
- To ensure that the vales do not make contact when starting, carefully rotate the engine at least two full revolutions.
-- When working on the chain drive perform an adaptation using the Vehicle Diagnostic Tester.
