18. Remove the cylinder head access plug (1,2).
19. Remove the right side secondary chain guide
(Refer to 9 - ENGINE/VALVE TIMING/TIMING
BELT/CHAIN AND SPROCKETS - REMOVAL).
CAUTION: The nut on the right side camshaft
sprocket should not be removed for any reason,
as the sprocket and camshaft sensor target wheel
is serviced as an assembly. If the nut was
removed, torque nut to 5 Nꞏm (44 in. lbs.).
20. Remove the retaining bolt and the camshaft drive
gear.
CAUTION: Do not allow the engine to rotate.
severe damage to the valve train can occur.
CAUTION: Do not overlook the four smaller bolts at the front of the cylinderhead.Donotattempttoremove
the cylinder head without removing these four bolts.
CAUTION: Do not hold or pry on the camshaft target wheel for any reason. A damaged target wheel can
result in a vehicle no start condition.
NOTE: The cylinder head is attached to the cylin-
der block with twelve bolts.
21. Remove the cylinder head retaining bolts.
22. Remove the cylinder head and gasket. Discard
the gasket.
CAUTION: Do not lay the cylinder head on its gas-
ket sealing surface, do to the design of the cylin-
der head gasket any distortion to the cylinder
head sealing surface may prevent the gasket from
properly sealing resulting in leaks.

CAUTION: The nut on the right side camshaft sprocket should not be removed for any reason, as the
sprocket and camshaft sensor target wheel is serviced as an assembly. If the nut was removed, torque nut
to 5 NM ( 60 in. lbs.).
7. Position the secondary chain (2) onto the camshaft drive gear, making sure one marked chain link is on either
side of the V6 mark (1) on the gear then using Special Tool 8428 Camshaft Wrench, position the gear onto the
camshaft.
CAUTION: Remove excess oil from camshaft sprocket retaining bolt before reinstalling bolt. Failure to do so
may cause over-torquing of bolt resulting in bolt failure.
8. Install the camshaft drive gear retaining bolt.
9. Install the right side secondary chain guide (Refer to 9 - ENGINE/VALVE TIMING/TIMING BELT/CHAIN AND
SPROCKETS - INSTALLATION).
10. Install the cylinder head access plug (1,2).
11. Re-set and install the right side secondary chain
tensioner (Refer to 9 - ENGINE/VALVE TIMING/
TIMING BELT/CHAIN AND SPROCKETS -
INSTALLATION).

INSPECTION
NOTE: Thoroughly inspect the connecting rod bearing bores and main bearing bores for scoring, blueing or
severe scratches. Further disassembly may be required.
If connecting rod bearing bores show damage, the cylinder heads must be removed to service the piston and rod
assemblies. If the bedplate or the cylinder block main bearing bores show damage the engine must be replaced.
1. If required, remove the main bearing halves from the cylinder block and bedplate.
2. Thoroughly clean the bedplate to cylinder block sealing surfaces and main bearing bores. Remove all oil and
sealant residue.
3. Inspect the bedplate main bearing bores for cracks, scoring or severe blueing. If either condition exists the
engine must be replaced.
4. Inspect the crankshaft thrust washers for scoring, scratches, wear or blueing. If either condition exist replace the
thrust washers.
5. Inspect the oil pan gasket/windage tray for splits, tears or cracks in the gasket sealing surfaces. Replace gasket
as necessary.
INSTALLATION
CAUTION: Main bearings are select fit. Refer to
Crankshaft Main Bearings in this section for
proper bearing selections.
CAUTION: When installing crankshaft, use care
not to damage bearing surfaces on the crankshaft.
NOTE: Apply sealant to the tone wheel retaining
screws prior to installation.
1. Lubricate upper main bearing halves with clean
engine oil.
2. Install the crankshaft tone wheel. Torque the
mountingscrewsto15Nꞏm(11ft.lbs.).
3. Position crankshaft in cylinder block.
4. Install the thrust washers (1).
