Camshafts
Inspection
NOTE:
. Do not rotate the camshaft during inspection.
. Removg the rocker arms and rocker shafts.
'L Put the camshafts and camshaft holders on the cylin-
der head. and then tighten the bolts to the specified
torque.
Specified Torque:
O -@: 8 mm botts 27 N.m {2.8 kgf.m,20 lbt'ft)
Apply engine oil to the threads,
O - @: 6 mm bolts 9.8 N.m (1.0 kgf m, 7.2 lbf'ft)
Seat the camshaft by pushing it toward the distribu-
tor end of the cylinder head.
Zero the dial indicator against the end of the distrib-
utor drive. then push the camshaft back and fonh
and read the end play.

4.Remove the bolts. then remove the camshaft hold-
ers from the cylinder head.
- Lift the camshaft out of the cylinder head, wipe
clean, then inspect the lift ramps. Replace the
camshaft if lobes are pitted, scored, or excessively
- Clean the camshaft bearing surfaces in the cylin
der head, then set the camshaft back in place,
- Insert a plastigage strip across each iournal.
Put the camshaft on the cylinder head. then install
the camshaft holders, and then tighten the bolts to
the specified torque as shown in the left column on
this page.
Remove the camshaft holders, then measure the
widest portion of the plastigage on each journal.

7. Apply a thin coat of clean engine oil to the outside
of the new valve guide. Install the guide from the
camshaft side of the head; use the special tool to
drive the guide in to the specified installed height. lf
you have all l6 guides to do, you may have to reheat
the head,

NOTE: For new valve guides onlY.
1. Coat both reamer and valve guide with cufting oil.
2. Rotate the reamer clockwise the full length of the
valve guide bore.
Continue to rotate the reamer clockwise while
removing it from the bore
Thoroughly wash the guide in detergent and water
to remove any cutting residue.
Check clearance with a valve lsee page 6-73)
. Verify that the valve slides in the intake and
exhaust valve guides without exertlng pressure.

Cylinder Head
Installation
lnstall the cylinder head in the reverse order of removal:
NOTE:
. Always use a new head and manifold gasket.. The cylinder head gasket is a metal gasket, Take carenot to bend it.
. Rotate the crankshaft, set the No. 1 piston at TDC (seepage 6-63).
. Do not use the middle cover and lower cover forstorang removed items.. Clean the middle cover and lower cover before instal_lation.
o Replace any washers that are damaged or deteriorated.
1. Install the cylinder head gasket, dowel pins and thehead oil control orifice on the cylinder head.
NOTE: Clean the oil control orifice when installing.

2, Tighten the cylinder head bolts in two steps. In thefirst step, tighten all bolts in sequence to about 29N.m (3.0 kgf.m, 22 tbf.ftl. ln the final step, tighten inthe same sequence to 83 N.m (8.S kgf.m,6t lbf.ft).
NOTE:
. Apply clean engine oil to the bolt threads andunder the bolt head.. We recommend using a beam-type torquewrench. When using a preset-type torque wrench,be sure to tighten slowly and not to overtighten.. lf a bolt makes any noise while you are torquing it,loosen the bolt, and retighten it from the 1st step.

Install the intake manifold and tighten the nuts in acflsscross pattern in two or three steps, beginningwith the inner nuts.. Always use a new intake manifold gasket.
Install the exhaust manifold and tighten the newself-locking nuts in a crisscross pattern in two orthree steps. beginning with the inner nuts.. Always use a new exhaust manifold gasket.

10. Align the marks on the cylinder head plug to thecylinder head upper surface, then install the cylin,
der head plug in the cylinder head.
PLUGReplace.
Install the timing belt (see page 6-63).
Adjust the valve clearance (see page 6-61).
Install the head cover gasket in the groove of the
cylinder head cover. Seat the recesses for the
camshaft first, then work it into the groove around
the outside edges,
NOTE:
. Before installing the head cover gasket, thorough-ly clean the head cover gasket and the groove.
. When installing, make sure the head cover gasket
is seated securely in the corners of the recesses
wrrn no gap.

14. Apply liquid gasket to the head cover gasket at theeight corners of the recesses.
NOTE:
. Use liquid gasket, Part No. 08718 - 0001 or 08718- 0003.
. Check that the mating surfaces are clean and drybefore applying liquid gasket
. Do not install the parts if five minutes or morehave elapsed since applying tiquid gasket.
Instead, reapply liquid gasket after removing oldrestdue.
. After assembly. wait at least 30 minutes before
filling the engine with oil.

15. 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
(toD of the semicircles).
Once the cylinder head cover is on the cylinder
head, slide the cover slightly back and forth to seat
the head cover gasket.
NOTE:
. Be{ore installing the cylinder head cover, clean
the cvlinder head contacting surfaces using a
shoP towel.
. Oo not touch the parts where liquid gasket was
applied.
. Replace any washer taht is damaged or deter'o-
rated.

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.
