COMPRESSION CHECK
HINT: If there is lack of power, excessive oil con–
sumption or poor fuel mileage, measure the cylinder
compression pressure.
1. WARM UP ENGINE
2. REMOVE SPARK PLUGS
3. DISCONNECT DISTRIBUTOR CONNECTOR
4. DISCONNECT COLD START INJECTOR CONNEC–
TOR
5. MEASURE CYLINDER COMPRESSION PRESSURE
(a) Insert a compression gauge into the spark plug hole.
(b) Fully open the throttle.
(c) While cranking the engine with the starter motor,
measure the compression pressure.
NOTICE: This test must be done for as short a time as
possible to avoid overheating of the catalytic converter.
HINT: A fully charged battery must be used to obtain
at least 250 rpm.
(d) Repeat steps
(a) through
(c) for each cylinder.
Compression pressure:
1,177 kPa (12.0 kgf/cm
2
, 171 psi)
Minimum pressure:
981 kPa (10.0 kgf/cm
2
, 142 psi)
Difference between each cylinder:
98 kPa (1.0 kgf/cm
2
, 14 psi) or less
(e) If cylinder compression in one or more cylinders is
low, pour a small amount of engine oil into the cylin–
der through the spark plug hole and repeat steps (a)
through
(c) for the low compression cylinder.
•
If adding oil helps the compression, chances are
that the piston rings and /or cylinder bore are
worn or damaged.
•
If pressure stays low, a valve may be sticking or
seating improperly, or there may be leakage past
the gasket.
6. CONNECT COLD START INJECTOR CONNECTOR
7. CONNECT DISTRIBUTOR CONNECTOR
8. INSTALL SPARK PLUGS
Torque: 18N–m (180 kgf–cm, 13ft–Ibf)
