1.
Warm up engine.
2.
Turn ignition switch OFF.
3.
Release fuel pressure.
Refer to EC-578, “Fuel Pressure Release”.
4.
Remove all spark plugs.
5.
Disconnect distributor coil connector.

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.

1.
Inspect belt for cracks, fraying, wear and oil. If necessary,
replace.
2.
Inspect drive belt deflection or tension at a point on the belt
midway between pulleys.
3.
Turn crankshaft two revolutions and re-check drive belt deflec-
tion or tension.
+
Inspect drive belt deflection or tension when engine is
cold.
+
Adjust if belt deflection exceeds the limit or if belt tension
is not within specifications.
