INSTALLATION
(1) Before installation of the balance shaft assem-
bly, the # 1 cylinder must be brought to TDC. Using
special tool VM.1051, roll engine over by hand until
tool can be inserted into engine block locking fly-
wheel from turning (Fig. 88). Once the # 1 cylinder is
brought to TDC, the balance shaft assembly can be
installed.
(2) With balance shaft assembly on work bench.
Insert special tool VM.1056 into balance shaft assem-
bly (Fig. 89). This will ensure proper balance shaft
and crankshaft timing after assembly.
(3) Install balance shaft assembly and retaining
bolts (Fig. 87). Torque bolts to 32.4N´m.
(4) Install oil pan (Refer to 9 - ENGINE/LUBRI-

NOTE: For applications with dual catalytic convert-
ers, repeat test on opposite converter using the
previous steps.
(7) If pressure exceeds maximum limits, inspect
exhaust system for restricted component. For further
catalytic converter inspection procedures, (Refer to 11
- EXHAUST SYSTEM/CATALYTIC CONVERTER -
INSPECTION). Replace component(s) as necessary.
EXHAUST BACK PRESSURE LIMITS
Exhaust Back Pressure Limit (Max)
Vehicle in Park/Neutral
(no load) RPM3.45 Kpa (0.5 psi)
INSPECTION
Inspect the exhaust pipes, catalytic converters,
muffler, and resonators for cracked joints, broken
welds and corrosion damage that would result in a
leaking exhaust system. Inspect the clamps, support
brackets, and insulators for cracks and corrosion
damage.
NOTE: Slip joint band clamps are spot welded to
exhaust system. If a band clamp must be replaced,
the spot weld must be ground off.
ADJUSTMENTS
A misaligned exhaust system is usually indicated
by a vibration, rattling noise, or binding of exhaust
system components. These noises are sometimes hard
to distinguish from other chassis noises. Inspect
exhaust system for broken, damaged or loose compo-
nents such as; clamps, heat shields, isolators, and
hanger brackets. Replace or tighten as necessary. It
is important that exhaust system clearances and
alignment be maintained.
Perform the following procedures to align the
exhaust system:
(1) Loosen band clamp at catalytic converter pipe
to muffler/resonator assembly.
(2) Align the exhaust system by inserting pipe
inward or outward until specification is achieved as
shown in (Fig. 2).
(3) Tighten band clamp to 54 N´m (40 ft. lbs.).

EXHAUST SYSTEM AND
TURBOCHARGER
DESCRIPTION
The basic exhaust system consists of an engine
exhaust manifold, turbocharger, exhaust down pipe,
exhaust pipe, exhaust heat shield(s), muffler and
exhaust tailpipe
The exhaust system uses a single muffler.
The exhaust system must be properly aligned to
prevent stress, leakage and body contact. If the sys-
tem contacts any body panel, it will transfer objec-
tionable noises originating from the engine to the
body.
When inspecting an exhaust system, critically
inspect for cracked or loose joints, stripped screw orbolt threads, corrosion damage and worn, cracked or
broken hangers. Replace all components that are
badly corroded or damaged. DO NOT attempt to
repair.
When replacement is required, use original equip-
ment parts (or equivalent). This will assure proper
alignment and provide acceptable exhaust noise lev-
els.
CAUTION: Avoid application of rust prevention com-
pounds or undercoating materials to exhaust sys-
tem floor pan exhaust heat shields. Light overspray
near the edges is permitted. Application of coating
will result in excessive floor pan temperatures and
objectionable fumes.
