6. Attach a compression tester to No. 1 cylinder.
7. Depress accelerator pedal fully to keep throttle valve wide
open.
8. Crank engine and record highest gauge indication.
9. Repeat the measurement on each cylinder.
+Always use a fully-charged battery to obtain specified
engine speed.
Compression pressure: kPa (kg/cm
2, psi)/rpm
Standard
1,275 (13.0, 185)/300
Minimum
1,079 (11.0, 156)/300
Difference limit between cylinders
98 (1.0, 14)/300
10. If compression in one or more cylinders is low:
1) Pour a small amount of engine oil into cylinders through spark
plug holes.
2) Retest compression.
+If adding oil helps compression, piston rings may be worn
or damaged. If so, replace piston rings after checking pis-
ton.
+If pressure stays low, a valve may be sticking or seating
improperly. Inspect and repair valve and valve seat. Refer
to SDS, EM-150. If valve or valve seat is damaged
excessively, replace them.
+If compression stays low in two cylinders that are next to
each other:
i)The cylinder head gasket may be leaking, or
ii)Both cylinders may have valve component damage.
Inspect and repair as necessary.

WARNING:
+Position vehicle on a flat and solid surface.
+Place chocks at front and back of rear wheels.
+Do not remove engine until exhaust system has com-
pletely cooled off, otherwise you may burn yourself and/or
fire may break out in fuel line.
+Before disconnecting fuel hose, release pressure. Refer to
EC-578, ªFuel Pressure Releaseº.
+Before removing front axle from transaxle, place safety
stands under designated front supporting points. Refer to
GI-43, ªGarage Jack and Safety Standº.
+Be sure to lift engine and transaxle in a safe manner.
+For engines not equipped with engine slingers, attach
proper slingers and bolts described in PARTS CATALOG.
CAUTION:
+When lifting engine, be sure to clear surrounding parts.
Use special care near accelerator wire casing, brake lines
and brake master cylinder.
+In lifting the engine, always use engine slingers in a safe
manner.
+In removing drive shaft, be careful not to damage grease
seal of transaxle.
+Before separating engine and transaxle, remove the

pilot bushing puller (SST).
7. Remove rear oil seal retainer.
+Insert a flat-bladed screwdriver between main bearing cap and
rear oil seal retainer to remove retainer.
8. Remove rear oil seal from rear oil seal retainer.
+Punch out with a flat-bladed screwdriver.
+Be careful not to damage rear oil seal retainer.

9. Remove piston and connecting rod assembly.
a. Set crankshaft pin of the removal location at a position close
to BDC.
b. Remove connecting rod cap.
c. Push piston and connecting rod assembly toward cylinder
head using a hammer handle.
+Before removing piston and connecting rod assembly, check
connecting rod side clearance. Refer to EM-225, ªCONNECT-
ING ROD SIDE CLEARANCEº.

CAUTION:
Tighten high-pressure rubber hose clamp so that clamp end is
3 mm (0.12 in) from hose end.
Tightening torque specifications are the same for all rubber
hose clamps.
Ensure that screw does not contact adjacent parts.

2. Remove connector from water in fuel filter sensor.
3. Remove fuel filter using a fuel filter wrench (commercial ser-
vice tool).
CAUTION:
Do not spill the fuel during removal. If the fuel is spilt, imme-
diately wipe it off. Be especially careful to prevent the fuel
from adhering to the insulators of the engine mounts.
4. Remove water in fuel filter sensor from fuel filter.
FUEL SYSTEMYD
Checking Fuel Lines
FE-15

Do not attempt to top up the fuel tank after the fuel pump nozzle
shuts off automatically. Continued refueling may cause fuel
overflow, resulting in fuel spray and possibly a fire.
WARNING:
To prevent ECM from storing the diagnostic trouble codes, do
not carelessly disconnect the harness connectors which are
related to the engine control system and TCM (Transmission
Control Module) system. The connectors should be discon-
nected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.

PRECAUTIONS FOR MULTIPORT FUEL INJECTION
SYSTEM OR ENGINE CONTROL SYSTEM
NLGI0001S04+Before connecting or disconnecting any harness connector for
the multiport fuel injection system or ECM:
Turn ignition switch to“OFF”position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
+Before disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure.
+Be careful not to jar components such as ECM and mass air
flow sensor.
PRECAUTIONS FOR THREE WAY CATALYSTNLGI0001S05If a large amount of unburned fuel flows into the catalyst, the cata-
lyst temperature will be excessively high. To prevent this, follow the
instructions below:
+Use unleaded gasoline only. Leaded gasoline will seriously
damage the three way catalyst.
+When checking for ignition spark or measuring engine
compression, make tests quickly and only when necessary.
+Do not run engine when the fuel tank level is low, otherwise the
engine may misfire, causing damage to the catalyst.
Do not place the vehicle on flammable material. Keep flammable
material off the exhaust pipe and the three way catalyst.
