lgnition Timing Inspection and Setting
2.
1.Check the idle speed, and adjust it if necessary (see
section 1 1).
Pull out the service check connector 2P (BRN and
BLK wires) from the connector holder located under
the dash on the front passenger side, then connect
the scs service connector (P/N 07PAz - 0010100) to
it.
Start the engine. Hold the engine at 3,000 rpm with
no load (A/T in N or E, Mff in neutral) until the
radiator fan comes on, then let it idle.
Connect the timing light to the No. I ignition wire,
then point the light toward the pointer on the timing
belt cover.
Check the ignition timing in no load conditions:
headlights, blower fan, rear window defogger, and
air conditioner are not operating.
lgnition Timing:
M/T: 16" 12" BTDC (RED) idling in neutral

Loosen the distributor mounting bolts, and turn the
distributor ignition (Dl) housing counterclockwise to
advance the timing or clockwise to retard the tim-

Loosen the adjusting screws.
Remove the camshaft holders.
Mark the rocker arms, then remove them.
Reinstall the camshaft and holders. Tighten the
camshaft holder bolts in a crisscross pattern, begin-
ning with the inner bolts.
9.8 N.m (1.0 kgf.m.7.2 lbf.ft)
Seat the camshafts by pushing them toward the dis-
tributor end of the head with a screwdriver.
Zero the dial indicator against the end of the
camshaft, push the camshaft back and forth and
read the end play.
Camshaft End Play:
Standard lNewl: 0.05 - 0.15 mm
10.002 - 0.005 in)
Service Limit: 0.5 mm (0.02 in)
Unscrew the camshaft holder bolts two turns at a
time, in a crisscross pattern, Then remove the
camshaft holder bolts from the cvlinder head.
Lift the camshafts out of the cylinder head. wipe
them clean, then inspect the lift ramps, Replace the
camshaft if any lobes are pitted, scored, or exces-
sively worn.
Clean the camshaft journal surfaces in the cylinder
head, then set the camshaft back in Dlace. Place aplastigage strip across each journal.
Install the camshaft holders. and torque the bolts tothe values and in the sequence shown on page 6-31.
NOTE: Do not rotate the camshafts during inspection.

11. Remove the camshaft holders. Measure the widest
portion of plastigage on each journal.
Camshatt-to HoldGr Oil Clearance:
Standard {Newl: 0.030 - 0.069 mm

Servico Limit: 0.15 mm (0.006 in)
12. lf camshaft-to-holder oil clearance is out of toler-
ance:
. And the camshaft has already been replaced,
you must replace the cylinder head.. lf the camshaft has not been replaced, first check
total runout with the camshaft suoDorted on V-
blocks.
Camshaft Total Runout:
Standard (N6w): 0.03 mm (0.001 in) max.
Service Limit 0.04 mm (0.(X)2 in)
Rotat6 camshattwhile measuring.
- lf the total runout of the camshafts is within tol-
erance, replace the cylinder head
- lf the total runout is out of tolerance, replace the
camshafts and recheck. lf the oil clearance is still
out of tolerance, replace the cylinder head.

Valve Guides
Valve Movement
1. Measure the guide-to-stem clearance with a dial
indicator while rocking the stem in the direction of
normal thrust (wobble method),
lntake Valve Stem-to-Guide Clearance:
Standard (Newl: 0.04 - 0.10 mm
(0.002 - 0.004 in)
Service Limit 0.16 mm (0.006 in)
Exhaust Valve Stem-to-Guide Clearance:
Standard {Newl: 0.10 - 0.16 mm
(0.004 - 0.006 inl
Service Limit: 0,22 mm (0.009 inl
lf the measurement exceeds the service limit,
recheck using a new valve.
lf the measurement is now within the service limit,
reassemble using a new valve.
lf the measurement still exceeds the limit, subtract the
O.D. of the valve stem, measured with a micrometer,
from the l.D. of the valve guide, measured with an
inside micrometer or ball gauge.
Take the measurements in three places along the
valve stem and three places inside the valve guide
The difference between the largest guide measure-
ment and the smallest stem measurement should
not exceed the service limit.
lntake Valve Stem-to-Guide Clearance:
Standard (New): 0.02 - 0.05 mm
{0.001 - 0.002 in)
Service Limit: 0.08 mm (0.003 in)
Exhaust Valve Stem-to-Guide Clearance:
Standard (New): 0.05 - 0.08 mm
(0.002 - 0.003 in)
Service Limit: 0.11 mm (0.004 in)

Replacement
1. As illustrated below, use a commercially available
air-impact valve guide driver attachment modified
to fit the diameter of the valve guides. In most
cases, the same procedure can be done using the
sDecial tool and a conventional hammer.

Select the proper replacement guides. and chill
them in the freezer section of a refrigerator for
about an hour.
Use a hot plate or oven to evenly heat the cylinder
head to 300"F (150"C). Monitor the temperature with
a cooking thermometer. Do not get the head hofter
than 300'F (150"C); excessive heat may loosen the
valve seaIs.

CAUTION: To avoid burns, uss heavy gloves when
handling the heated cylinder head.

7.Place the rocker arms on the pivots and the valve
stems. Put the rocker arms in their original posi-
lrons.
lnstall the camshafts, then install the oil seals with
the open side (spring) facing in. Make sure that the
keyways on the camshafts are facing up and the No.
1 piston is at TDC.
Clean and dry the cylinder head mating surfaces.
Apply liquid gasket (P/N 08718 - 0001 or 08718 -
0OO3) to the head mating surfaces of the No. 1 and
No. 6 camshaft holders on both the intake and
exhaust side.

holders.
. The arrows marked on the camshaft holders
should point at the timing belt.
Tighten each bolt in two steps to ensure that the
rockers do not bind on the valves.

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.
