(1) Install upper main bearing shells into engine
block (Fig. 121).
(2) Lubricate upper main bearing shells with clean
engine oil.
(3) Install the crankshaft.
(4) Install lower main bearing shells into main
bearing caps (Fig. 121).
(5) Install
each
main
bearing
cap
in
proper
sequence and direction (Fig. 122). Tighten all bolts
finger tight.
(6) Tighten the main cap bolts in the following
tightening sequence:
• Step 1 Tighten main bearing cap bolts 1–12 in
the sequence order shown in (Fig. 123) to 20 N·m (15
ft. lbs.). This will seat the bearing caps onto the
engine block.
• Step 2 To ensure correct thrust bearing align-
ment the following procedure must be done:
a. Move crankshaft all the way to the rear of its
travel.
b. Then, move crankshaft all the way to the
front of its travel.
c. Wedge an appropriate tool between the rear of
the cylinder block and rear crankshaft counter-
weight. This will hold the crankshaft in it’s most
forward position.
• Step A1—tighten the A1 bolts to 61 N·m (45 ft.
lbs.) in the sequence order shown in (Fig. 123).
• Step A2—tighten the A2 bolts to 115 N·m (85 ft.
lbs.) in the sequence order shown in (Fig. 123).
• Step A3—tighten the A3 Bolts to 54 N·m (40 ft.
lbs.) in the sequence order shown in (Fig. 123).
(7) Remove the holding tool.
(8) Install new connecting rod bearings.
(9) Install rod caps. Install NEW connecting rod
bolts. Bolt threads should be oiled with engine oil.
Torque connecting rod bolts to 68 N·m (50 ft. lbs.).
(10) Install the crankshaft oil scraper and tighten
nuts to 23 N·m (200 in. lbs.) (Fig. 118).
(11) Install oil pump pick up tube using a new
o-ring. Torque 1/4–20 bolt to 11 N·m (95 in. lbs.).
Torque 5/16–18 nut to 23 N·m (200 in. lbs.) (Fig.
117).
(12) Install
the
crankshaft
rear
oil
seal
and
retainer (Refer to 9 - ENGINE/ENGINE BLOCK/
CRANKSHAFT REAR OIL SEAL RETAINER -
INSTALLATION).

EXHAUST SYSTEM
DESCRIPTION - EXPORT
The exhaust system on this model is equipped with
vacuum-operated Diverter Valves, an Auxiliary Reso-
nator, and the associated piping. The auxiliary com-
ponents are used to modify the exhaust flow during
certain driving conditions. The Diverter Valves are
controlled by vacuum and actuated by the Exhaust
Solenoid.
OPERATION - EXPORT
During certain driving conditions, the vehicles
exhaust flow will be diverted away from the side
exits, and redirected to the Auxiliary Resonator at
the rear of the vehicle. During the activation mode,
the butterfly valves in the Exhaust Diverter Valves
are closed. The BCM monitors engine speed, engine
rpm, and manifold pressure and uses these inputs to
activate or deactivate the Exhaust Diverter Valves.
The BCM controls the Exhaust Solenoid Relay, which
when energized will activate the Exhaust Solenoid.
The Exhaust Solenoid then uses engine vacuum to
activate the Exhaust Diverter Valves. The Diverter
