NOTE:
. Valves should be adjusted only when the cylindsrhead temperature is less than 100"F (38"C).
. After adjusting, retorque the crankshaft pulley bolt(see page 6-16).

NOTE; Refer to page e46 when installing the cytinderhead cover.
2. Remove the upper cover (see page 6-19).
3. Set the No. 1 piston at TDC. The "UP" mark on the
cam-shaft pulley should be at top, and the TDC
marks should align with the cylinder head surface.

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.

Glearance
1.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 one strip of plastigage across each main jour-
na l.
NOTE: lf the engine is still in the car when you bolt
the main cap down to check clearance, the weight
of the crankshaft and flvwheel will flaften the plasti-
gage further than just the torque on the cap bolt.
and give you an incorrect reading. For an accurate
reading, support the crank with a jack under the
counterweights and check only one bearing at a
time,
Reinstall the bearings and caps, then torque the
bolts.

lf the plastigage measures too wide or too narrow,
(remove the engine if it's still in the car), remove the
crankshaft, and remove the upper half of the bear-
ing. Install a new. complete bearing with the same
color code {select the color as shown on the next
page), and rechsck the clearance.
CAUTION: Do nol fil€, shim, or scrape the bearings
or tho cap3 to adiust cleatanc€.
lf the plastigage shows the clearance is still incor-
rect, try the next larger or smaller bearing (the color
listed above or below that one), and check again
NOTE: lf the proper clearance cannot be obtained
by using the appropriate larger or smaller bearings,
replace the crankshaft and start over.
