Parts Requiring Angular Tightening
lUse an angle wrench for the final tightening of the following
engine parts:
(1) Cylinder head bolts
(2) Connecting rod cap nuts
lDo not use a torque value for final tightening.
lThe torque values for these parts are for a preliminary step.
lEnsure thread and seat surfaces are clean and coated with
engine oil.
Liquid Gasket Application Procedure
a. Use a scraper to remove all traces of old liquid gasket
from mating surfaces and grooves. Also, completely
clean any oil from these areas.
b. Apply a continuous bead of liquid gasket to mating sur-
faces. (Use Genuine Liquid Gasket or equivalent.)
lFor oil pan, be sure liquid gasket diameter is 3.5 to 4.5
mm (0.138 to 0.177 in).
lFor areas except oil pan, be sure liquid gasket diam-
eter is 2.0 to 3.0 mm (0.079 to 0.118 in).
c. Apply liquid gasket around the inner side of bolt holes
(unless otherwise specified).
d. Assembly should be done within 5 minutes after coating.
e. Wait at least 30 minutes before refilling engine oil and
engine coolant.

Measurement of Compression Pressure
1. Warm up engine.
2. Turn ignition switch OFF.
3. Release fuel pressure.
Refer to EC section (ªFuel Pressure Releaseº, ªBASIC SER-
VICE PROCEDUREº).
4. Remove all spark plugs.
lClean area around the plug with compressed air before
removing the spark plug.
5. Disconnect camshaft position sensor harness connector at
the distributor.
6. Disconnect all fuel injector harness connectors.
7. Attach a compression tester to No. 1 cylinder.
8. Depress accelerator pedal fully to keep throttle valve wide
open.
9. Crank engine and record highest gauge indication.
10. Repeat the measurement on each cylinder as shown above.
lAlways use a fully-charged battery to obtain specified
engine speed.
Compression pressure: kPa (bar, kg/cm
2, psi)/rpm
Standard
1,226 (12.26, 12.5, 178)/300
Minimum
1,030 (10.30, 10.5, 149)/300
Difference limit between cylinders
98 (0.98, 1.0, 14)/300
11. If 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.
lIf adding oil improves cylinder compression, piston
rings may be worn or damaged. If so, replace piston
rings after checking piston.
lIf pressure stays low, a valve may be sticking or seating
improperly. Inspect and repair valve and valve seat.
(Refer to SDS, EM-2049 and EM-2051.) If valve or valve
seat is damaged excessively, replace it.
lIf 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.
12. Reconnect fuel pump fuse, all fuel injector harness
connectors, and the camshaft position sensor harness con-
nector at the distributor, and then reinstall spark plugs.
