COMPRESSION CHECK
HINT: If there is lack of power, excessive oil consumption or
poor fuel economy, measure the compression pressure.
1. WARM UP AND STOP ENGINE
Allow the engine to warm up to normal operating tempera-
ture.
2. DISCONNECT COLD START INJECTOR CONNECTOR
3. DISCONNECT DISTRIBUTOR CONNECTOR
4. REMOVE SPARK PLUGS (See page IG±6 or 11)
5. CHECK CYLINDER COMPRESSION PRESSURE
(a) Insert a compression gauge into the spark plug hole.
(b) Fully open the throttle.
(c) While cranking the engine, measure the compression pres-
sure.
HINT: Always use a fully charged battery to obtain engine
speed of 250 rpm or more.
(d) Repeat steps (a) through (c) for each cylinder.
NOTICE: This measurement must be in as short a time
as possible.
Compression pressure:
12.5 kg±cm
2 (178 psi, 1,226 kPa) or more
Minimum pressure:
10.0 kg/cm
2 (142 psi, 981 kPa)
Difference between each cylinder:
1.0 kg/cm
2 (14 psi, 98 kPa) or less
(e) if the cylinder compression in one or more cylinders is low,
pour a small amount of engine oil into the cylinder through
the spark plug hole and repeat steps (a) through (e) for cyl-
inders with low compression.
wIf adding oil helps the compression chances are that the pis-
ton rings and/or cylinder bore are worn or damaged.
wIf pressure stays low, a valve may be sticking or seating is im-
proper, or there may be leakage past the gasket.
6. REINSTALL SPARK PLUGS (See page IG±7 or 11)
Torque: 180 kg±cm 0 3 ft±Ib, 18 N±m)

9. SLIGHTLY JACK UP ENGINE
Raise the engine enough to remove the weight from the en-
gine mounting on the right side.

ing cover for damage and check for correct gasket
installation. Check for foreign material on the pulley
teeth.
