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

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.

lnstallation
Before installing the pistons, apply a coat of
engine oil to the ring grooves and cylinder
bores.
lf the crankshaft is already installed:
. Set the crankshaft to BDC for each cylinder.
. Remove the connecting rod caps, and slip short
sections of rubber hose over the threaded ends
of the connecting rod bolts.
. lnstall the ring compressor. check that the bear-
ing is securely in place, then position the piston
in the cylinder, and tap it in using the wooden
handle of a hammer.
o Stop after the ring compressor pops free, and
check the connecting rod-to-crank journal align-
ment before pushing the piston into place
. Apply engine oil to the bolt threads. Install the
rod caps with bearings, and torque the nuts to:

lf the crankshaft is not installed:
. Remove the rod caps and bearings, install the ring
compressor, then position the piston in the cylin-

hammer.
. Position all Distons at top dead center.

lnstallation
Before installing the crankshaft, apply a coat of
engine oil to the main bearings and rod bearings.
Insert the bearing halves into the cylinder block and
connecting rods.
Hold the crankshaft so the rod journals for cylinders
No.2 and No. 3 are straight down.
Lower the crankshaft into the block, seating the rod
journals into connecting rods No. 2 and No. 3, and
install the rod caps and nuts finger-tight.

NOTE: Install caps so the bearing recess is on the
same side as the recess in the rod.
Check rod bearing clearance with plastigage (see
page 7-11), then torque the capnuts. Apply engine
oil to the bolt threads.

Use this procedure to tighten the filter if eight num-
bers (1 to 8) are printed on the surface of the filter.
1) Make a mark on the oil filter base under the num-
ber that shows at the bottom of the filter when
the rubber seal is seated.
2l Tighten the filter by turning it clockwise seven
numbers from the marked point. For example, if a
mark is made under the number 2 when the rub
ber seal is seated, the filter should be tightened
until the number 1 comes up to the marked point'

CAUTION: Using any procedure other than those
shown could rosult in serious engins damage due
to oil leakage
5. After installation. fill the engine with oil up to the spec-
ified level, run the engine for more than three minutes,
then check for oil leakage

Testing
lf the oil pressure warning Iight stays on with the engine
running, check the engine oil level. It the oil level is cor-
rect:
1. Connect a tachometer'
2. Remove the engine oil pressure switch, and install an
oal pressure gauge.

Start the engine. Shut it off immediately if the gauge
registers no oil pr€ssure. Repair the problem before
continuing.
Allow the engine to reach operating temperature (tan
comes on at least tlivice). The pressure should be;
Engine Oil Temperature: 176"F (80"C1
Engine Oil Pressulo:
At ldle: 69 kPa (0.7 kgf/Gm' . 10 Psi)

. lf the oil Dressure is within specifications, replace
the oil pressure switch and recheck.
. lf the oil pressure is NOT within specifications,
inspect the oil pump (see page 8-10).
