Check that the mating surfaces are clean and dry.
Apply liquid gasket, part No. 08718 - 0001 or 08718- 0003, to the head cover gasket at the eight corners
of the recesses.
NOTE:
. Do not install the parts if five minutes or more
have elapsed since applying liquid gasket.
Instead, reapply liquid gasket after removing old
residue.
. After assembly. wait at least 30 minutes before
filling the engine with oil.
Apply liquid gasket tothe shaded areas.
Hold the head cover gasket in the groove by placing
your fingers on the camshaft holder contacting sur-
faces (top of the semicirclesl.
Once the cylinder head cover is on the cylinder
head, slide the cover slightly back and forth to seat
the head cover gasket.
Inspect the cover washers. Replace any washer that
is damaged or dete(iorated.

step, tighten all nuts, in sequence. to 9.8 N.m (1.0
kgf.m, 7.2 lbf.ft).
Check that all tubes, hoses and connectors are
installed correctly.

Clearance
To check main bearing-to-journal oil clearance,
remove the main caps and bearing halves.
Clean each main journal and bearing half with a
clean shop towel.
Place a strip of plastigage across each main journal.
NOTE: lf the engine is still in the vehicle when you
bolt the main cap down to check clearance, the
weight of the crankshaft and flywheel will flatten
the plastigage further than just the torque on the
cap bolt, and give you an incorrect reading. For an
accurale reading, support the crank with a jack
under the counterweights and check only one bear-
Ing aI a Irme.
Reinstall the bearings and caps, then torque the
bolts,

NOTE: Do not rotate the crankshaft during inspec-
tron.
Remove the bearing cap again, and measure the
widest part of the plastigage.

lf the plastigage measures too wide or too narrow,(remove the engine if it's still in the vehicle),
remove the crankshaft, and remove the upper half
of the bearing. Install a new, complete bearing with
the same color code (select the color as shown on
the next page). and recheck the clearance, Do not
file, shim, or scrape the bearings or the caps to
adjust the clearance.
lf the plastjgage shows the clearance is still incor-
rect, try the ne)d larger or smaller bearing {the color
listed above or below that one), and check again. lf
the proper clearance cannot be obtained by using
the appropriate larger or smaller bearings, replace
the crankshaft and start over.

to run the engine at idling speed until it reaches
normal operating temperature, then continue to run
it for approximatelY 15 minutes.

Dry the crankshaft oil seal housing.
Apply a light coat of grease to the crankshsft and to

When the seal is in place, clean any excess grease
off the crankshaft and check that the oil seal lip is
not distorted,

NOTE: Refer to section 23 for the fuel gauge system cir-cuit diagram.
'1. Check the No. 25 METER (7.5 A) fuse in the under-dash fuse/relay box before testing.
2. Fold the left rear seat cushion forward, and remove
the base frame cover {see section 20).
3. Remove the access panel from the floor.
4. Disconnect the 5P connector from the fuel pump.
5. Measure voltage between the 5P connector termi-nals No.2 and No. 5 with the ignition switch ON ( ).There should be between 5 and 8 V.

Turn the ignition switch OFF.
Attach a jumper wire between the No. 2 and No. 5terminals, then turn the ignition switch ON fll).
Check that the pointer of the fuel gauge starts mov-ing toward the "F" mark. Turn the ignition switchOFF before the pointer reaches "F" on the gauge
dial. Failure to do so may damage the luel gauge.
NOTE: The fuel gauge is a bobbin (cross-coil) type,hence the fuel level is continuously indicated evenwhen the ignition switch is OFF, and the pointer
moves more slowly than that of a bimetal type.
. lf the pointer of the fuel gauge does not move atall. replace the gauge.
. lf the gauge is OK, inspect the fuel gauge send-ing unit.
