Installthe cylinder head in the reverse order of removal:
1. Clean the cylinder head and block surfaces.
2. Clean the oil control orifice. Install the cylinder headgasket, dowel pins and the oil control orifice on thecylinder block. Always use a new cylinder head gas-ket.

4. Tighten the cylinder head bolts in two steps. In thefirst step tighten all bolts, in sequence, to about 29
N.m {3.0 kgf.m,22 lbf.ft); in the finat step, tighten inthe same sequence to 85 N.m (8.7 kgf.m,63 lbf.ft).
Use a beam-type torque wrench. When using a pre-
set-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 1st step.

Clearance
To check main bearing-to-journal oil clearance,
remove the main caps and bearing halves.
Clean each main journal and bearing half with a
clean shop towel.
Place a strip of plastigage across each main journal.
NOTE: lf the engine is still in the vehicle when you
bolt the main cap down to check clearance, the
weight of the crankshaft and flywheel will flatten
the plastigage further than just the torque on the
cap bolt, and give you an incorrect reading. For an
accurale reading, support the crank with a jack
under the counterweights and check only one bear-
Ing aI a Irme.
Reinstall the bearings and caps, then torque the
bolts,
1st step:25 N'm (2.5 kgf.m, 18lbf.ft)
Final siep: 76 N'm 17.8 kgl.m, 56 lbf.ftl
NOTE: Do not rotate the crankshaft during inspec-
tron.
Remove the bearing cap again, and measure the
widest part of the plastigage.

Service Limit: 0.06 mm 10.002 in)
lf the plastigage measures too wide or too narrow,(remove the engine if it's still in the vehicle),
remove the crankshaft, and remove the upper half
of the bearing. Install a new, complete bearing with
the same color code (select the color as shown on
the next page). and recheck the clearance, Do not
file, shim, or scrape the bearings or the caps to
adjust the clearance.
lf the plastjgage shows the clearance is still incor-
rect, try the ne)d larger or smaller bearing {the color
listed above or below that one), and check again. lf
the proper clearance cannot be obtained by using
the appropriate larger or smaller bearings, replace
the crankshaft and start over.

Remove the upper bearing halves from the connecting
rods, and set them aside with their respective caps.
Reinstall the main caps and bearings on the engine
in proper order.
lf you can feel a ridge of metal or hard carbon
around the top of each cvlinder, remove it with a
ridge reamer. Follow the reamer manufacturer's
instructions. lf the ridge is not removed, it may
damage the pistons as they 8re pushed out.

Use the wooden handle of a hammer to drive the
pistons out.
13.Reinstall the connecting rod bearings and caps after
removing each piston/connecting rod assembly.
To avoid mixup on reassembly, mark each piston/
connecting rod assembly with its cylinder number.
NOTE: The existing number on the connecting rod
does not indicate its position in the engine, it indi-
cates the rod bore size.
