• Carefully release the camshaft carrier from the cylinder head, then lift the carrier from
the cylinder head complete with the VVC assemblies.
• Ensure that both inlet camshafts are retained in the carrier, then invert the assembly
• Slacken, but do not remove the 2 bolts securing the VVC housings to the carrier.
IMPORTANT: Sufficiently slacken the 2 bolts to enable the timing plates 18G 1770/1 and
18G 1770/2 to be fitted.

retaining bolts and washers.
CAUTION: Identify each VVC assembly in its fitted position an DO NOT attempt to
interchange the front and rear assemblies.

cylinder head, then using a stick magnet, remove the hydraulic tappets keeping them in
