Setting valve clearance
Standard tools:
Feeler gauges
Attention!
In case of internal exhaust gas recircula-
tion, the inlet valve is opened briefly by an
additional cam on the camshaft.
This is not to be confused with the valve
overlap.
Allow the engine to cool down for at least
30 minutes before setting the valve
clearance. Engine oil temperature < 80 °C
The following work procedure describes
the setting of the valve clearance on an
inlet valve. The procedure is the same for
the setting on an outlet valve, taking into
consideration the setting dimension.
Unscrew all screws (1).
Remove cylinder head cowling (2).
Remove gasket.
