COMPRESSIONPRESSURE

mm
(O.79 In)dls.

Use compressor testerwhose end(rubber
portion) isless than 20mm (0.79 in)dia.
Otherwise, itmay becaught bycylinder
head during removal.

SEM387CMeasurement
ofCompression Pressure

1. Warm upengine.
2. Turn ignition switchoff.
3. Cut fuel line.
Release fuelpressure.
Refer to"Releasing FuelPressure" inEC section. •
4. Remove allspark plugs.
5. Disconnect distributorcentercable.
6. Attach acompression testertoNO.1 cylinder.
7. Depress accelerator pedalfullytokeep throttle valvewide
open.
8. Crank engine andrecord highest gaugeindication.
9. Repeat themeasurement oneach cylinder asshown above.

• Always useafully-charged batterytoobtain specified
engine revolution.

If
compression inone ormore cylinders islow:
a. Pour asmall amount ofengine oilinto cylinders through
spark plugholes.
b. Re-test compression,

• Ifadding oilhelps compression, pistonringsmaybeworn
or damaged. Ifso, replace pistonringsafterchecking pis-
ton.
• Ifpressure stayslow,avalve maybesticking orseating
improperly. Inspectandrepair valveandvalve seat.Refer
to SOS (EM-156, 159).Ifvalve orvalve seatisdamaged
excessively, replacethem.
• Ifcompression stayslowintwo cylinder thatarenext to
each other:
The cylinder headgasket maybeleaking, or
both cylinders mayhave valve component damage.
Inspect andrepair asnecessary.

Removal
1. Remove undercovers.
2. Drain engine oil.
3. Remove frontexhaust tube.Refer to"Exhaust system"inFE
section.
4. Remove centermember.
5. Remove enginefrontandrear gussets.
6. Remove enginelowerrearplate (AfTmodels).
7. Remove oilpan.
(1) Insert Toolbetween cylinderblockandoilpan.

• Becareful nottodamage aluminum matingface.
• Do not insert screwdriver, oroil pan flange willbe
deformed.

(2) Slide Toolbytapping itsside withahammer, andremove
oil pan.
