When turning the crankshaft at the front of the engine (clutch cover end) always turn
anticlockwise.
When turning the crankshaft at the rear of the engine (alternator cover end) always
turn clockwise.
Turning the crankshaft in the wrong direction may cause the camshaft drive chain to
slip on the camshaft sprockets resulting in incorrect camshaft timing.
Accurate camshaft timing can only be obtained using the correct timing method and
service tools as described below.
The camshaft sprockets are attached to the camshafts using slotted bolt holes. This
allows for very accurate valve timing and therefore improved performance and fuel
economy. Never fit the camshaft sprockets without correctly setting the camshaft
timing using the service tools and timing procedure described below. Severe engine
damage will result from incorrect valve timing adjustment.
1. If not already installed, make sure the two gear teeth with an alignment mark on each
is visible and central in the hole for the crankshaft locking pin and install the service
tool T3880501.
