NOTE:
Mark the installation position of the
push-rod with an appropriate marker
(e.g. a touch-up pen) (e.g. "IV1" for in-
take valve cylinder 1).
NOTE:
If the parts are installed again with the
same position and allocation as befo-
re they were removed, the push-rods
can be reused. The reason for this is
the break-in which takes place on the
parts prior to removal.
Step Procedure
5 Lift the intake manifold with the fuel rail
slightly and carefully pull the entire cylin-
der head off the cylinder with both hands.
6 Hold both push-rods in position in the oil
return bores. Hold the oil bore closed with
a finger and remove the cylinder head.
7 Remove 16x5 O-rings from the oil return
tubes and the crankcase.
