Installation (cont'dl
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.

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-
der, and tap it in using the wooden handle of a
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.

connecting rods No, 1 and No.4, 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.

Oil Filter
Replacement
After the engine has been run, the exhaust pipe willbe hot; be careful when working around ihe exhaustpipe.
Be careful when loosening the drain bolt whils theengine is hot. Burns can resuh because the oil tem-peratu16 is very high.
Remove the oil filter with the oil filter wrencn.
Inspect the threads and rubber seal on the new filter.Wipe off the seat on the engine block, then apply alight coat of oil to the new filter,s rubber seal.
NOTE: Use onty fitters with a built-in bypass sys,tem.
Apply oil to rubber sealbefore installing.

Inspect threads andrubber seal surface.

Install the oil filter by hand.
After the rubber seal seats, tighten the oil filter clock_wise with the oil filter wrench.

OIL FILTER WRENCH07912 - 6110001

Oil Pressure
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

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).

OilJet (B1642 engine)
Inspection
1.Remove the oil jet (see page 8-3) and inspect it asfollows.
Make sure that a 1.1 mm (0.04 in) diameter drillwill go through the nozzte hole (j.2 mm (0.05 in)diameter).
Insert the other end of the same 1.1 mm (0.04 in)drill into rhe oil intake (i.2 mm (0.05 in) diame_ter).
Make sure the check ball moves smoothly andhas a stroke of approximately 4.0 mm (0.16 in).Check the oil jet operation with an air nozzle. ltshould take at least 200 kPa (2.0 kgf/cm,, 28 psi)to unseat the check ball.
NOTE: Replace the oil jet assembly if the nozzlers damaged or bent.

Testing
!@ Do not smoke during the test, Keep open
flame away from your work atea,
lf you suspect a problem with the fuel pump, check that the
fuel pump actually runs; when it is ON (ll), you will hear
some noise if you hold your ear to the fuel fill port with the
fuel fill cap removed. The fuel pump should run for two
seconds when ignition switch is first turned ON (ll). lf the
fuel pump does not make noise, check it as follows:
L Remove the seat cushion {see section 20).
2. Remove the access panel from the floor.
3. Make sure the ignition switch is OFF, then discon-
nect the Iueltank 2P connector.
4. Connect the PGM-FI main relay 7P connector termi-
nal No. 4 and No. 5 with a jumper wire.
