! Inspect for tuel leakage (see section 1ll.. After assembling fuel line parts, turn on the
ignition switch (do not operate the staner) so
that the fuel pump operates for approximately
two seconds and the fuel line pressurizes.
Repeat this operation two or three times and

Valve Clearance
Adjustment (cont'dl
Adjust valve clearances on No. 1 cylinder.
Intske: 0.08 - 0.12 mm (0.003 - 0.005 inl
Exhaust: 0.15 - 0.20 mm (0.006 - 0.008 inl
Loosen the locknut and turn the adjusting screw
until feeler gauge slides back and forth with a slight
amount of drag.
7. Rotate the crankshaft 180' counterclockwise to
bring No. 4 piston to TDC. The "UP" mark should
be pointing straight down. Adjust valves on No. 4
cylinder.
Number 4 piston at TDC:
LOCKNUT9x0.75mm25 N.m {2.5 kgl.m, 18lbtft}
Tighten the locknut and recheck clearance again,
Repeat adjustment if necessary.
Rotate the crankshaft 180' counterclockwise(camshaft pulley turns 90'). The "UP" mark should
be on the exhaust side. Adjust valves on No,3 cylin-
der.
8. Rotate the crankshaft 180' counterclockwise to
bring No. 2 piston to TDC. The "UP" mark should
be on the intake side. Adjust valves on No. 2 cylin-
der.

NOTE: Refer to page 6-31 when installing cylinder head
cover.

Valve Seals
Replacement (cylinder head removal not required)
The procedure shown below applies when using the in-
car valve spring compressor (Snap-on YA8845 with
Y AAA45-2A 1 /8" attachment).
!@@ When using this tool, as with any tool,
always use approved eye protection. Using the
fight tool tor each job helps increase productivity
while safeguarding tools, equipment and ihe user.
Turn the crankshaft so that the No. 1 and the No. 4pistons are at top dead center (TDC).
Remove the cylinder head cover.
Remove the distributor.
Loosen and disconnect the timinq belt from the
camshaft oullevs.
5. Remove the camshaft holder bolts, then remove the
camshaft holders, the camshafts and rocker arms.
Intake Valve Seals
6. Using the 6 mm bolts supplied with the tool, mount
the two uprights to the cylinder head at the end
camshaft holders. The uprights fit as shown.
7. Insert the cross shaft through the bottom hole of
the two uprights.
8.
9.
10.
Select the 7/8 in. diameter long compressor attach-
ment and fasten the attachment to the No. 4 hole of
the lever arm with the speed pin supplied.
Position the piston at TDC and insen an air adaptor
into the spark plug hole. Pump air into the cylinder
to keep the valve closed while compressing springs
and removing the valve keepers.
Position the lever arm under the cross shaft so the
lever is perpendicular to the shaft and the compres-
sor attachment rests on top of the retainer for the
spring being compressed. Use the rear position slot
on the lever as shown.
NOTE: Put shop towels over the oil passages toprevent the valve keepers from falling into the cylin-
der head.

Oil Pressure
Testing
lf the oil pressure warning light stays on with the enginerunning, check the engine oil level. It the oil level iscorrect:
Connect a tachometer.
Remove the oil pressure switch and install an oil pressure gauge.
Start the engine. Shut it off immediately if the gaugeregasters no oil pressure. Repair the problem beforecontinuing.
Allow the engine to reach operating temperature (fan
comes on at least twicel. The pressure should be:
Engine Oil Pressure:
At ldle: 70 kPa {O.7 kgficmr, tO psil
minimum
At 3,OOO rpm: 34O kPa (3.5 kgf/cmr, 50 psil
minimum
a lf oilpressure is within specifications, replace theengine oil pressure switch and recheck.
a lf oil pressure is NOT within specifications,rnspect the oil pump (see page g-11).

Oil Jet
lnspection(818C1, 818C5 engines
only)
1. Remove the oil jet (see pages 8 4 or 8 5) and inspectit as follows.
a Make sure rhat a 1 .1 mm (O.04 in) diameter drillwillgo through the nozzle hole fl.2 mm (O.O5 in)diameter).
a Insert the other end of the same 1 .1 mm {0.O4in) drill into the oit intake (1.2 mm (0.05 in)diameter).
Make sure the check ball moves smoothly and hasa stroke of approximately 4.0 mm (O.16 in).a Check the oil jet operation with an air nozzle. ltshould take at least 2OO kPa 12.O kg|lcm2, 2gpsi) to unseat the check ball.
NOTE: Replace the oiljet assembly if the nozzleis damaged or bent.
2. Mounting torque is critical. Be very precise when in-stalling.
Torque: 16 N.m (1.6 kgf.m, 12 lbf.ftl

8.Mix the recommended antifreeze with an equal
amount of water in a clean container.
NOTE:
a Use only genuine Honda antifreeze/coolant.
a For best corrosion protection, the coolant concen-
tration must be maintained year-round at 500,6
minimum. Coolant concentrations less than 507o
may not provide sufficient protection against cor,
rosion or freezing.
a Coolant concentrations greater than 60% will im-
pair cooling efliciency and are not recommended.
CAUTION:
a Do not mix different brands of anti-lrcezel
coolants.
a Do not use additional rust inhibitots or anti-tustproducts; they may not be compatible with the
coolant.
