Note
♦ Cylinder head and cylinder head cover must be renewed
together.
♦ After installing camshafts wait for approx. 30 minutes before
starting engine. The hydraulic compensation elements must
settle (otherwise valves will strike pistons).
♦ After working on the valve gear, turn the engine carefully
at least 2 rotations to ensure that none of the valves make
contact when the starter is operated.
♦ Always renew gaskets and seals.
♦ After working on the chain drive, adapt learnt values in en‐
gine control unit. To do this, switch on ignition, and select
the following menu option on vehicle diagnostic tester:
♦ 0001 - Engine electronics, functions
♦ 0001 - Basic setting
♦ Timing chain length compensator, reset after re-
newing chain
