Chapter 2 Part B 2.OL and 2.4L four-cylinder engines
10.15 To measure camshaft endplay, set up a dial indicator with
the plunger of the indicator in line with the camshaft, as shown -
gently pry the camshaft all the way to the rear, zero the indicator,
then pry the camshaft all the way to the front-the reading on the
indicator Is the endplay measurement
15 Remove the rocker arms and shafts from the camshaft bearing caps
(see Section 5). Temporarily install the bearing caps, in their proper posi-
tions, and tighten the bolts to the torque listed in this Chapter’s Specifica-
tions. Usingadialindicator,checkthecamshaftendplay(seeillustration)
and compare it to this Chapter’s Specifications.
16 If the endplay is excessive, replace the camshaft and/or the cylinder
head.
Ins talla tion
17 Liberally coat the journals and thrust portions of the camshaftwith as-
sembly lube or engine oil.
18 Carefully install the camshaft in the cylinder head.
Caution: If the
camshaft was notproperly marked before removal, installit with the lobes
facing DOWN or away from the rocker arms. This will set the engine at
TDC number 1 (provided the crankshaft hasn’t been rotatedsince Step 1).
19 Coat a new camshaft oil seal with engine oil and press it into place
with a hammer and a deep socket.
20 Assemble and install the rocker arm assembly, tightening the bolts to
the torque listed in this Chapter’s Specifications (see Section 5).
21 Install the camshaft sprocket and tighten the bolt to the torque listed in
this Chapter’s Specifications.
22 Install the timing belt (see Section 8).
11.4 Carefully label the wires and hoses to aid in reassembly
23 Temporarily set the valve clearances prior to engine start-up (see
Chapter 1).
Note:
Latermodels use hydrauliclashadjusters on theintake
and exhaust valves but the jet valve must still be adjusted manually.
24 Reinstall the remaining parts in the reverse order of removal.

_____
25 Starttheengine and allow ittowarm up, then adjustthe ignition timing
(see Chapter 1).
26 Readjust the valve clearancesas described in Chapter 1.
27 Reinstall the valve cover and run the engine while checking for oil 1
leaks.
11 Intake manifold - removal and installation
1 Relieve the fuel system pressure (see Chapter 4) then disconnect
the negative cable from the battery.
2 Drain the cooling system (see Chapter 1).
Removal
Carbureted models
Refer to illustrations 11.4 and 11.8
’ 3 Remove the air cleaner (see Chapter 4).
4 Clearly label
(see illustration)
and disconnect all hoses, wires,
brackets and emission lines which run to the carburetor and intake man-
ifold. Several components may be slipped out of brackets and laid overthe
carburetor
(see illustration).
