1. Warm up engine.
2. Turn ignition switch OFF.
3. Release fuel pressure.
Refer to ªReleasing Fuel Pressureº in EC section.
4. Remove ignition coils.
5. Remove spark plugs.
IClean 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.
IAlways 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)/300
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.
IIf adding oil improves cylinder compression, piston rings
may be worn or damaged. If so, replace piston rings after
checking piston.
IIf pressure stays low, a valve may be sticking or seating
improperly. Inspect and repair valve and valve seat. Refer
to SDS, EM-178. If valve or valve seat is damaged
excessively, replace them.
IIf 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 ªSelf-diagnosis Procedureº referring to EC section.
Erase DTC if any DTC appears.

AEM308 20 mm (0.79 in) dia.
Use compression tester whose end (rubber
portion) is less than 20 mm (0.79 in) dia.
Otherwise, it may be caught by cylinder
head during removal.

7. Remove oil pan.
a. Insert Tool between cylinder block and oil pan.
1)Be careful not to damage aluminum mating face.
Do not insert screwdriver, or oil pan flange will be dam-
aged.
b. Slide Tool by tapping on the side of the Tool with a hammer.
InstallationNCEM00101. Use a scraper to remove old liquid gasket from mating surface
of oil pan.
IAlso remove old liquid gasket from mating surface of cyl-
inder block.
2. Apply a continuous bead of liquid gasket to mating surface of
oil pan.
IUse Genuine Liquid Gasket or equivalent.
IApply to groove on mating surface.
IAllow 7 mm (0.28 in) clearance around bolt holes.
IBe sure liquid gasket diameter is 3.5 to 4.5 mm (0.138 to
0.177 in).
IAttaching should be done within 5 minutes after coating.
3. Install oil pan.
ITighten oil pan nuts and bolts in the numerical order.
IWait at least 30 minutes before refilling engine oil.
4. Install parts in reverse order of removal.
