8.9 Remove the exhaust manifold nuts from the exhaust
manifold. Be sure to soak the nuts with penetrating oil before
attempting to remove them.
1 Reed valve bracket 5 Exhaust manifold
2 Heat shield
6 Exhaust manifold gasket
3 Ground cable
7 Exhaust manifold-to-exhaust
4 Reed valve assembly
pipe gasket
17 Using a scraper, remove all traces of old gasket material from the cyl-
inder head and manifold mating surfaces. Clean the surfaces with lacquer
thinner or acetone.
18
Install the intake manifold with a new gasket and tighten the bolts fin-
ger-tight. Starting at the center and working out in both directions, tighten
the bolts in a criss-cross pattern until the torque listed in this Chapter’s
Specifications is reached.
19 The remainder of the installation procedure is the reverse of removal.

Exhaust manifold - removal and installation
Removal
Refer to illustration 8.9
1
Disconnect the negative battery cable from the battery.
2 Drain the cooling system (see Chapter 1).
3 Remove the air cleaner (see Chapter 4).
4 Loosen the power steering pump and remove the belt (see Chap-
ter 1).
5 Raise the front of the vehicle and support it securely on jackstands.
Detach the exhaust pipe from the exhaust manifold (see Chapter4). Apply
penetrating oil to the fastener threads if they are difficult to remove.
6 Disconnect the air injection tube assembly (pulse air feeder) if
equipped, and move the tube assembly to one side.
7
Remove the power steering pump (if equipped) and set it aside (see
Chapter 10).
8 Remove the heat shjeld from the exhaust manifold. Be sure to soak
the bolts and nuts w&h penetrating oil before attempting to remove them
9.6 Timing chain cover installation details
1 Pulley bolt and washer
4 Gasket
assembly 5 Access cover
2 Pulley 6 Gasket
3 Timing chain cover
7 Front seal
from the manifold.
9 Remove the exhaust manifold nuts (see illustration) and detach the
exhaust manifold.
IO Separate the front catalytic converter from the exhaust manifold.
Ins talla tion
11 Discard the old gaskets and use a scraper to clean the gasket mating
surfaces on the manifold and head, then clean the surfaces with a rag
soaked in lacquer thinner or acetone.
12 Place the exhaust manifold andconverterassembly in position on the
cylinder head and install the nuts. Starting at the center, tighten the nuts in
a criss-cross pattern until the torque llsted in this Chapter’s Specifications
IS reached.
13 The remainder of installation is the reverse of removal.
14 Start the engine and check for exhaust leaks between the manifold
and the cylinder head and between the manifold and the exhaust pipe.
9 Silent shaft chain/sprockets -removal, inspection
and installation
Note: When a loose silent shaft drive chain is suspected as the cause of
excessive no/se. the tens/on must be adjusted. it is possible to do this pro-
cedure without removing the bming charn cover (see Step 17).
Removal
Refer to illustrations 9.6 and 9.8
1 Disconnect the cable from the negative terminal of the battery. Re-
move the air cleaner assembly. Drain the engine coolant (see Chapter 1).
2 Remove thedrivebelts, cooling fan and pulley. Remove the alternator,
power steering pump, air conditionrng compressor (if equipped) and re-
lated brackets, and lay them aside. Warning: Theairconditioningsystem
is under high pressure - don’t disconnect the hoses.
3 Remove the valve cover (see Section 4). Remove the front two cylin-
der head-to-timing chain cover bolts. Caution: Do not loosen any other
cylinder head bolts. Remove the distributor (see Chapter 5).
4 Raise the vehicle and support it securelyon jackstands. Remove the
splash guard. Remove the large bolt at the front of the crankshaft and slide
the pulley off. Note: To keep the crankshaft from turning while you’re re-
moving this bolt, remove the starter (see Chapter 5) and wedge a large
screwdriver into the f/ywhee//driveplate ring gear. Note: If the pulley does
notcome off easily, pullers are available atautopatts stores that willmake
removal easy.
