the engine to check and adjust the camshaft timing and remove or
replace the cam chain. This kit also includes the VANOS plate which is required to lock the variable valve timing system in the correct position. Preparation Due
to positioning of the chain drive it will be necessary to remove the
sump for removal or refitting the timing chain and sprocket. The engine should be set at TDC no.1. As
a precautionary check the camshafts are in their TDC No 1 position when
the slots in the end of the cams is facing vertically and the cam lobes on No 1cylinder are pointing vertically and slightly outwards. If the timing needs to be adjusted the camshaft sprockets bolts will need to be loosened. The camshaft sprocket retaining bolts should not be re-used.
