Liquid Gasket Application Procedure
NLEM0002
1.
Use a scraper to remove old liquid gasket from mating
surfaces and grooves. Also, completely clean any oil from
these areas.
2.
Apply a continuous bead of liquid gasket to mating sur-
faces. (Use Genuine Liquid Gasket or equivalent.)
+
For oil pan, be sure liquid gasket diameter is 3.5 to 4.5 mm
(0.138 to 0.177 in).
+
For areas except oil pan, be sure liquid gasket diameter is
2.0 to 3.0 mm (0.079 to 0.118 in).
3.
Apply liquid gasket around the inner side of bolt holes
(unless otherwise specified).
4.
Assembly should be done within 5 minutes after coating.
5.
Wait at least 30 minutes before refilling engine oil and
engine coolant.

2.
Turn ignition switch OFF.
3.
Release fuel pressure.
Refer to EC-43, “Releasing Fuel Pressure”.
4.
Remove ignition coils.
5.
Remove spark plugs.
+
Clean area around plug with compressed air before removing
the spark plug.

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 as shown above.
+
Always use a fully-charged battery to obtain specified
engine speed.
Compression pressure: kPa (bar, kg/cm
2
, psi)/rpm
Standard
1,324 (13.24, 13.5, 192)/350
Minimum
1,128 (11.28, 11.5, 164)/350
Maximum allowable difference between cylinders
98 (0.98, 1.0, 14)/350
10. If 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 retest compression.
+
If adding oil improves cylinder compression, piston rings
may be worn or damaged. If so, replace piston rings after
checking piston.
+
If pressure stays low, a valve may be sticking or seating
improperly. Inspect and repair valve and valve seat. Refer
to SDS, EM-70. If valve or valve seat is damaged
excessively, replace them.
+
If compression in any two adjacent cylinders is low and if add-
ing oil does not improve compression, there is leakage past the
gasket surface. If so, replace cylinder head gasket.
11. Reinstall spark plugs, ignition coils and fuel pump fuse.
12. Perform “Self-diagnosis Procedure” referring to EC-69, “How
to Erase DTC” if any DTC appears.
