Measurement of Compression Pressure
1.
Warm up engine.
2.
Turn ignition switch off.
3.
Release fuel pressure.
Refer to “Releasing Fuel Pressure” in EC-section.
4.
Remove all spark plugs.
5.
Disconnect distributor center cable.
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 for each cylinder.
I
Always use a fully-charged battery to obtain specified
engine revolution.
Compression pressure:
kPa (bar, kg/cm
2
, psi)/300 rpm
Standard
1,275 (12.75, 13.0, 185)
Minimum
1,079 (10.79, 11.0, 156)
Difference limit between cylinders
98 (0.98, 1.0, 14)
10. If cylinder compression in one or more cylinders is low:
A: pour a small amount of engine oil into cylinders through
spark plug holes.
B: retest compression.
I
If adding oil helps compression, piston rings may be worn
or damaged. If so, replace piston rings after checking pis-
ton condition.
I
If pressure stays low, a valve may be sticking or seating
badly. Inspect and repair valve and valve seat. (Refer to
SDS). If valve or valve seat is damaged excessively,
replace them.
I
If compression stays low in two cylinders that are next to
each other:
A. The cylinder head gasket may be leaking, or
B. Both cylinders may have valve component damage.
Inspect and repair as necessary.

20 mm (0.79 in) dia
Compression tester rubber adaptor
diameter should be less than 20 mm (0.79 in)
to prevent fouling with cylinder head.

Removal
1.
Remove engine under cover.
2.
Drain engine oil.
3.
Remove steel oil pan bolts.
4.
Remove steel oil pan.
a.
Insert Tool between aluminum oil pan and steel oil pan.
I
Be careful not to damage aluminum mating surface.
I
Do not insert screwdriver, or oil pan flange will be
deformed.
