. Adjust the tension of the following drive belts.
Alternator belt {see section 23).
P/S pump belt (see section 171.
A/C comDressor belt (see section 22).
! Inspect for tuel leakage (see section 1ll.. After assembling fuel line parts, turn on the
ignition switch (do not operate the staner) so
that the fuel pump operates for approximately
two seconds and the fuel line pressurizes.
Repeat this operation two or three times and
check for tuel leakage at any point in the {uel
line.

Cylinder Head
Wapage
NOTE: lf camshaft-to-holder oil clearances (see page 6
22) arc nol within specification, the head cannot be
resurfaced.
lf camshaft-to-holder oil clearances are within specifica-
tions, check the head for warpage.
lf warpage is less than 0.05 mm (0.002 in) cylinder
head resurfacing is not required.
lf warpage is between 0.05 mm (0.002 in) and 0.2 mm
(0.008 in). resurface cylinder head.
Maximum resurface limit is 0.2 mm (0.008 in) based
on a height of 132.0 mm (5.20 in).
Measure along edges, and 3 ways across center.

lnstallation
Install the cylinder head in the reverse order of removal:
NOTE:
. Always use a new head gasket.
. Cylinder head and cYlinder block surface must be
clean.
. "UP" mark on the camshaft pulleys should be at the
to p.
. Do not use the middle cover and lower cover for stor-
ing removed items.
. Clean the middle cover and lower cover before instal-
lation.
. Replace the washer when damaged or deteriorated
L Cylinder head dowel pins and the oil control orifice
must be aligned.
. When hand'ing a metal gasket, care should be
taken not to fold it or damage the contact surface
of the gasket.
. Clean the oil control orifice when installing,

lnstall the rubber seal in the groove of the cylinderhead cover. Seat the seal in the recesses for thecamshaft first, then work it into the groove aroundthe outside edges.
NOTE:
. Before installing the rubber seal, thoroughlyclean the seal and the groove.
. When installing, make sure the seal is seatedsecurely in the corners of the recesses with nogap.

18.Apply liquid gasket to the rubber seal at the eightcorners of the recesses.
NOTE:
. Use liquid gasket, Part No. 08718 - OO01 or 08718- 0003.
. Check that the mating surfaces are clean and drybefore applying liquid gasket.. Do not installthe parts if 5 minutes or more naveelapsed since applying liquid gasket. Instead,reapply liquid gasket after removing old residue.. After assembly, wait at least 30 minutes beforefilling the engine with oil.
Apply liquid gasket tothe shaded areas.

To check main bearing-to-iournal oil clearance,
remove the main caps and bearing halves.
Clean each main iournal and bearing half with a
clean shop towel.
Place one strip of plastigage across each main iour-
na l-
NOTE: lf the engine is still in the car when you bolt
the main cap down to check clearance, the weight
of the crankshaft and flywheel will flatten the plasti'
gage further than just the torque on the cap bolt,
and give you an incorrect reading. For an accurate
reading, support the crank with a jack under the
counterweights and check only one bearing at a
trme.
Reinstall the bearing caps and cap bridge (B18C1,
B18C5 engines only)then torque the bolts.

NOTE: Do not rotate the crankshaft during inspec-
tro n.
Remove the cap bridge (818C1, 818C5 engines
only), caps and bearings again, and measure the
widest part of the plastigage.

PLASTIGAGE STRIP
lf the plastigage measures too wide or too narrow,
{remove the engine if it's still in the car), remove the
crankshaft, and remove the upper half of the bear-
ing. lnstall a new, complete bearing with the same
color code (select the color as shown in the right
column), and recheck the clearance.
CAUTION: Do not file, shim. or scrape the bearings
or the caps to adiust clearance.
lf the plastigage shows the clearance is still incor-
rect, try the next larger or smaller bearing (the color
listed above or below that one), and check again.
NOTE: lf the oroDer clearance cannot be obtained
by using the appropriate larger or smaller bearings.
reolace the crankshaft and start over.

CAUTION: lf the codes ale indecipherable because of
an accumulation oI dirt and dust, do not scrub them
with a wire bru6h or scraper. Clean lhem only with sol-
vent or detergent.
