11. When installing the cylinder head cover, hold the
head cover gasket in the groove by placing your fin-
gers on the camshaft holder contacting surfaces
(top of the semicircles)
Set the spark plug seal on the spark plug tube.
Once the cylinder head cover is on the cylinder
head, slide the cover slightly back and forth to seat
the head cover gasket.
NOTE:
. Before installing the cylinder head cover, clean
the cylinder head contacting surfaces with a
shop towel.
. Do not touch the parts where liquid gasket was
aDolied.
. Take care not to damage the spark plug seals
when installing the cylinder head cover,
. Visually check the spark plug seals for damage.
. Replace any washer that is damaged or deterio-
rated.

Adjustment
NOTE:
. Valves should be adjusted only when the cylinder
head temperaturs is less than 100'F (38'C)'
. After adjusting, retorque the crankshaft pulley bolt to
177 N.m (18.0 kgf'm, 130 lbt'ft)
1. Remove the cylinder head cover'
NOTE: Refer to page G86 when installing the cylin-
der head cover.
2. Set No. 1 pi$on at TDC. The "UP" mark on the pullsy
should be at the top, and TDC grooves on the pulley
should align with the pointer on the back cover' TDC
grooves {white paint) on the crankshaft pulley should
align with the pointer on the timing belt lower cover'

cutting the
Carefully cut a 45o seat, removing only enough mate-
rial to ensure a smooth and concentric seat.
Bevel the upper edge of the seat with the 30" cutterand the lower edge of the seat with the 60. cutter.Check width of seat and adjust accordingly,
Make one more very light pass with the 45" cutter toremove any possible burrs caused bv the other cut-
ters.

5. After resufacing the seat. inspect for even valveseating: Apply Prussian Blue Compound to thevalve face, and insert the valve in its original loca-tion in the head. then lift it and snap it closedagainst the seat several times.
PRUSSIAN BLUE COMPOUND
The actual valve seating surface, as shown by theblue compound, should be centered on the seat.. lf it is too high (closer to the valve stem), you mustmake a second cut with the 60. cutter to move itdown, then one more cut with the 45. cutter torestore seat width.
. lf it is too low (closer to the valve edge), you must
make a second cut with the 30. cutter to move itup. then one more cut with the 45. cutter to restoreseat width.
NOTE: The final cut should always be made withthe 45" cutter,
7. Insen the intake and exhaust valves in the head and
measure valve stem installed heioht.

16. Tighten the nuts in two or three steps. In the final
step, tighten all nuts, in sequence, to 9 8 N'm {1 0
kgf.m, 7.2 lbf.ft).
NOTE: After assembly, wait at least 30 minutes
before filling the engine with oil.
After installing, check that all tubes' hoses and con-
nectors are installed correctly.17.

Cylinder BlockPiston Pins
Bore Honing
1.Measure cylinder bores as shown on page 7-16. lf the
block is to be reused, hone the cylinders and remea-
sure the bores.
Hone cylinder bores with honing oil 8nd a fine (400
grit) stone in a 60 degree cross-hatch pattern.
NOTE:
. Use only a rigid hone with 400 grit or finer stone
such as Sunnen, Ammco, or equivalent.
. Do not use stones lhat are worn or broken.
When honing is complete, thoroughly clean the
engine block of all metal particles. Wash the cylin-
der bores with hot soapY water, then dry and oil
immediately to prevent rusting.
NOTE: Never use solvent. it will only redistribute the
grit on the cylinder walls.
lf scoring or scratches are still present in cylinder
bores after honing to the service limit, rebore the
cylinder block.
NOTE: Some light vertical scoring and scratching is
acceptable if it is not deep enough to catch your fin-
gernail and does not run the full length of the bore.
