and the letters stamped on the crank (codes for rod jour-
nal size), to choose the correct bearings.

Before installing the piston, apply a coat ofengine oil to the ring grooves and cylinder bores.
lf the crankshaft is already installed:
. Remove the connecting rod caps and slip short
sections of rubber hose ove. the threaded ends
of the connecting rod bolts.
a Install 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.
Stop after the ring compressor pops free and
check the connecting rod-to-crank journal align-
ment before tapping piston into place.
. Install the rod caps with bearings, then torque
the nuts,

Piston Rings
Replacement
1.Using a ring expander, remove old piston rings.
Clean all ring g.ooves thoroughly.
NOTE:
. Use a squared-oJf broken ring or ring groove
cleaner with blade to fit piston grooves.
. Top ring groove is 1.0 mm (0.039 in) wide, sec-
ond groove is 1.2 mm (0.047 in) wide. and oil
ring groove is 2.8 mm (0.110 in) wide.. File down blade if necessary.
CAUTION: Do not use a wire brush to cloan thr
ring lands, or cut ring lands dsopo. with cl€aning
tool.
NOTE: lf the piston is to be separated from the con-
necting rod, do not install new rings yet.
Install new rings in the prope. sequence and posi-
tion (see page 7-18).
NOTE: Do not use old piston rings.

Eight numbers {'l to 8) are printed on the surface of
rhe filter.
The following explains the procedure for tightening
filters using these numbers.
1 ) Make a mark on the cvlinder block under the num-
ber that shows al the bottom of the filter when
the rubber seal is seated.
2) Tighten the tilter by turning it clockwise seven
numbers from the marked point. For example, if
a mark is made under the number 2 when the tub-
ber seal is seated. the filter should be tightened
until the number 'l comes up to the marked point.

specified level, run the engine for more than 3
minutes, then check for oil leakage and oil level.

Oil Pressure
Testing
lf the oil pressure warning light stays on with the enginerunning, check the engine oil level. lf the oil level is
correct:
1. Connect a tachometer.
2. Remove the oil pressure switch and install an oil pres-
sure gauge.
3. Stan the engine. Shut it off immediately if the gauge
registers no oil pressure. Repair the problem before
continuing.
4. Allow the engine to reach operating temperatu,e {fancomes on at least twice). The Dressure should be:
Engine Oil Pressure:
At ldle: 70 kPa (0.7 kgf/cmr, 10 psi)
minimum
At 3,OOO lpm: 340 kPa {3.5 kgf/cmz, 50 psi}
minimum
a lJ oil pressure is within speciJications, replace the
engine oil pressure switch and recheck.
a lf oil pressure is NOT within specifications, in-
spect the oil pump (see page 8-1O).

Oil Jet
Inspection (B18C1 engine only|
Remove the oil jet (see page 8-4) and inspect it as
follows.
a Make sure that a I .l mm (O.04 in) diameter drill
will go through the nozzle hole {1 .2 mm {O.OS in)
diameterl.
a Insert the other end of the same 1.1 mm (O.O4
in) drill into the oil intake {1.2 rnm {0.05 in}
diameter).
Make sure the check ball moves smoothlv and has
a stroke of approximately 4.0 mm {O. 16 in).a Check the oil jet operation with an air nozzle. lt
should take at least 2OO kPa (2.O kgf/cmr,28
Dsi) 10 unseat the check ball.
NOTE: Replace the oiljet assembly if the nozzle
is damaged or bent.

stalling.

3. Fuel Cut-oft Control
a During deceleration with the throttle valve closed, current to the {uel injectors is cut otJ to improve fuel economy
at speeds over tollowing rpm:
. 8188l engine: 91O tpm (Canada model: 1,O50 rpm)
. 818C1 engine: 95O tpm (Canada model: l,O5O rpm)
a Fuel cut-olf action also takes place when engine speed exceeds, 7,O0O rpm {81 8B1 engine), 8,1O0 rpm (B 18Cl
engine), regardless oI the position of the throttle valve, to protect the engine from ovet-revving.
A/C Compressor Clutch Relay
When the ECM receives a domand for cooling trom the air conditioning system, it del8ys the compressor from being
enetgized, and enriches the mixture to assure smooth transition to the A/C mode.
Evaporative Emission (EVAP) Purge Control Solenoid Valve
When the engine coolant tempersture is below 163oF {73"C), the ECM supplies a ground to the EVAP pu.ge control
solenoid valve which cuts vacuum to the EVAP purge control diaphragm valve.
Intake Air Bypsss (lAB) Control Sol€noid Valve
When the engine rpm is below 5,750 rpm, the IAB control solenoid valve is activated by a signal from the ECM,
intske air flows through the long intake path, then high torque is delivered. At spaeds highe. than 5,750 rpm, the
solenoid valve is deactivated by the ECM, and intake air flows through the short intake path in order to reduce the
resistance in airflow.
ECM fail-safe/bEck-up Functions
1. Fail-sate Function
When an abnormality occurs in a signal from a sensor, the ECM ignores that signal and assumes a pre-progtammed
value tor that sensor that allows the engine to continue to run.
Back-uD Function
When an abnormalitv occurs in the ECM itself, the fuel iniectors are controlled by a back-up citcuit independent of
the system in order to permit minimal driving.
Self-diagnosis Function IMaltunction Indicator Lamp {MlL)1
Wh6n an abnormality occurs in a signal from a sensor, the ECM supplies ground for the MIL and stores the code
in erasable memory. When the ignition is initially turned on, the ECM supplies ground tor the MIL tor two seconds
to check the MIL bulb condition.
Two Trio Detection Method
To prevent tals€ indications, th€ Two Trip Dstection Method is used for the HO2S and fuel metering-related self-
diagnostic tunctions. When an abnormslity occurs, the ECM stores it in its memo.y. Wh€n the ssme sbnormality
recurs alter the ignition switch is turned OFF and ON ag8in, the ECM informs the driver by lighting the MlL.
However, to ease troubleshooting, this function is canc€ll€d when you short the service check connector. The MIL
will then blink immedistelv when an abnormality occurs.
