Valve Installation'alve Inslallauon -
When installing valves in the cylinder head, coat
valve stems with oil belore inserting them into valve
guides, and make sure valves move up and down
smoothly.
When valves and springs are in place, lightly tap the
end of each valve stem two or three times to ensure
proper seating of valves and valve keepers (use plas
tic mallet).
NOTE: Tap the valve stem only along lts axrs so you
do not bend the stem.

Measure the guide to stem clearance with a dial indica-
tor while rocking the stem in the direction of normal
thrust {wobble method).

Standard {Newlr 0.04 - 0.10 mm
10.002 - 0.004 in)

Service Limit: 0.22 mm (0.009 in)
Valve extended 10 mm out from seat
lf measurement exceeds the service limit, recheck
usrng a new valve.
lf measurement is now within the service limit,
reassemble using a new valve.
lf measurement still exceeds limit, recheck using
alternate method below, then replace valve and
guide, if necessary.
NOTEr An alternate method of checking guide to stem
clearance is to subtract the O.D. of the valve stem, mea-
sured with a micrometer, from the l.D. o{ the valve
guide, measured with an inside micrometer or ball
ga uge.
Take the measurements in three places along the valve
stem and three places inside the valve guide.
The diiference between the largest guide measurement
and the smallest stem measurement should not exceed
the service limit

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.

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.

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
