COMPRESSIONPRESSURE

Measurement ofCompression Pressure

1. Warm upengine.
2. Turn ignition switchoff.
3. Release fuelpressure.
Refer to"Releasing FuelPressure" inEC section.
4. Remove allspark plugs.
5. Disconnect distributorcoilconnector.

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

SEM387C6.
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 speed.
Compression pressure:kPa(bar, kg/cm
2,
psi)/300 rpm
Standard 1,226 (12.26, 12.5,178)
Minimum 1,030 (10.30, 10.5,149)
Difference limitbetween cylinders
98 (0.98, 1.0,14)

10. Ifcompression inone ormore cylinders islow:
a. Pour asmall amount ofengine oilinto cylinders through
spark plugholes.
b. Retest compression.
• If
adding oilhelps compression, pistonringsmaybeworn
or damaged.
If
so, replace pistonringsafterchecking pis-
ton.
• Ifpressure stayslow,avalve maybesticking orseating
improperly. Inspectandrepair valveandvalve seat.Refer
to
50S.
If
valve orvalve seatisdamaged excessively,
replace them.
• There isleakage pastthegasket surface ifthe following is
observed. Compression intwo adjacent cylinders islow and
adding oildoes notimprove compression.
If
so, replace
cylinder headgasket.
