(1) Remove cylinder head covers. Refer to proce-
dures outlined in this section.
(2) Rotate engine until number one cylinder is at
TDC on the EXHAUST stroke.
(3) View the intake camshaft sprocket timing
mark. The mark should be 90° from the cylinder
head cover sealing surface (Fig. 23) on both right and
left cylinder banks.
(4) Count chain pins from the mark on the intake
camshaft towards the exhaust camshaft. Engine is
timed correctly when there are 12 chain pins
between the timing marks on the intake camshaft
and exhaust camshaft (Fig. 23).
(5) If marks are not correctly aligned, proceed to
Camshafts, Timing Chain and Sprockets, Removal
and Installation procedures.

ENGINE HYDRO-MOUNT ISOLATORS
Engine hydro-mounts may show surface cracks,
this will not effect performance and hydro-mount
should not be replaced. Only replace the engine
hydro-mounts when leaking fluid:
• Driveshaft distress: Refer to Driveshafts in Sus-
pension, Group 2.
• Any front end structural damage (after repair).
• Isolator replacement.
