Spark Plug Inspection
1.Inspect the electrodes and ceramic insulator.
Burned or worn electrodes may be caused by:. Advanced ignition timing. Loose spark plug
. Plug heat range too hot.Insufficientcooling
Fouled plug may be caused by:. Retarded ignition timing. Oil in combustion chamber. Incorrect spark plug gap
. Plug heat range too cold. Excessive idling/low speed running. Clogged air cleaner element. Deteriorated ignition coils
Worn or deformedelectrodes
Do not adjust the gap of iridium tip plugs (A);
replace the spark plug if the gap is out of
specification.
Electrode Gap:
Standard (New): 1.0 1.1 mm
{0.039-0.0€ in.)
Service Limit: 1.3 mm {0.051 in.l

3. Replace the plug at the specified interval, or if the
center electrode is rounded {A). Use onlV the spark
plugs listed below.
Spark Plugs: lZFR6Kl1 (NGK)
SKJ2ODR-M11 (DENSO)
Apply a small quantity of anti-seize compound to
the plug threads, and screw the plugs into the
cylinder head finger-tight. Then torque them to
18 N m (1.8 kgf.m, 13lbf ft).

\Drive Belt Auto-tensioner Inspection
1.Check whether there is a change in the position of
the auto-tensioner indicator before starting the
engine and after starting the engine. lf there is a
change in the position, replace the auto-tensioner.
3.
Check for abnormal noise from the tensioner pulley.
lf abnormal noise is heard, replace the tensioner
pulley.
Remove the drive belt (see page 4-26).
lMove the auto-tensioner within its limit with the
belt tension release tool in the direction shown.
Check that the tensioner moves smoothly and
without any abnormal noise. lf the tensioner does
not move smoothly or there is abnormal noise,
replace the auto-tensioner.

8.
Remove the auto-tensioner (see page 4-28).
Install the tensioner pulley.
Clamp the auto-tensioner (A) by using two 8 mm
bolts (B) and a vise (C) as shown. Do not clamp the
auto-tensioner itself .
Set the torque wrench (D) on the pulley bolt.
Align the indicator {E) on the tensioner base with
center mark (F) on the tensioner arm by using the
torque wrench, and measure the torque. lf the
torque value is out of specification, replace the
auto-tensioner,
NOTE; lf the indicator exceeds the center mark,
recheck the torque.
Auto-tensioner spring torque:
26.5-36.3 N.m 12.7-3.7 kg.m, 19.5-26.8lbt.ft)

Cylinder Head Inspection for
Warpage
Remove the cylinder head {see page 6-23).
Inspect the camshaft (see page 6-29).
Check the cylinder head for warpage. Measure
along the edges, and three ways across the center.
. 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 the cylinder head.. Maximum resurface limit is 0.2 mm (0.008 in,)
based on a height of 104 mm (4.09 in.).

and disassemble it (see page 6-27).
2. Put the rocker shaft holders, camshaft, and
camshaft holders on the cylinder head, then tighten
the bolts to the specified torque.

3. Seat the camshaft by pushing it away from the
camshaft pulley end ofthe cylinder head.
4. Zero the dial indicator against the end of the
camshaft, then push the camshaft back and forth
and read the end play. lf the end play is beyond the
service limit, replace the camshaft head and
recheck. lf it is still beyond the service limit, replace
the cylinder.

Unscrew the camshaft holder bolts two turns at a
time, in a crisscross pattern. Then remove the
camshaft holders from the cylinder 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
excessively worn,
Clean the camshaft journal surfaces in the cylinder
head, then set the camshafts back in place. Place a
plastigage strip across each journal.
Install the camshaft holders, then tighten the bolts
to the specified torque as shown in step 2.
Remove the camshaft holders. Measure the widest
portion of plastigage on each journal.
. lf the camshaft-to-holder clearance is within
limits, go to step 1 1.. lf the camshaft-to-holder clearance is beyond the
service limit and the camshaft has been replaced,
replace the cylinder head.. lf the camshaft-to-holder clearance is beyond the
service limit and the camshaft has not been
replaced, go to step 10.

on V-blocks,
.lfthetotal runout of the camshaft is within the
service limit, replace the cylinder head.. lf the total runout is beyond the service limit,
replace the camshaft and recheck the camshaft-
to-holder oil clearance. lf the oil clearance is still
beyond the service limit, replace the cylinder
neao.

Tighten the cylinder head bolts in sequence to 39N.m {4.0 kgf.m, 29 lbf.ft). Use a beam-type torquewrench. When using a preset-type torque wrench,be sure to tighten slowly and do not overtighten. lf
a bolt makes any noise while you are torquing it,
loosen the bolt and retighten it from the first step.
9.After torquing, tighten all cylinder head bolts in twosteps (90" per step). lf you are using a new cylinderhead bolt, tighten the bolt an extra 90..
