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.

PRECAUTIONS AND PREPARATIONKA24DE
EM-2002

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.

Removal
1. Raise vehicle and support it with safety stands.
2. Remove engine under cover.
3. Drain engine oil.
4. Remove front final drive together with differential mounting
member. Refer to PD section (ªRemoval and Installationº,
ªFront final driveº) Ð 4WD models only.
5. Remove front suspension member.
6. Remove oil pan bolts.
7. Remove oil pan.
a. Insert Tool between cylinder block and oil pan.
lBe careful not to damage aluminum mating surface.
lDo 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.
8. Pull out oil pan from front side.

OIL PANKA24DE
EM-2011

Installation
1. Use a scraper to remove old liquid gasket from mating sur-
face of oil pan.
lAlso remove traces of liquid gasket from mating surface
of cylinder block.
2. Apply a continuous bead of liquid gasket to mating surface
of oil pan.
lUse Genuine Liquid Gasket or equivalent.
lApply to groove on mating surface.
lAllow 7 mm (0.28 in) clearance around bolt hole.
lBe sure liquid gasket diameter is 3.5 to 4.5 mm (0.138 to
0.177 in).
lAttaching should be done within 5 minutes after coating.
3. Install oil pan.
lTighten oil pan bolts in numerical order.
: 5.9 - 6.9 Nzm (0.6 - 0.7 kg-m, 52 - 61 in-lb)
lWait at least 30 minutes before refilling engine oil.
4. Install parts in reverse order of removal.

Removal
CAUTION:
lAfter removing the timing chain, do not turn crankshaft
and camshaft separately, or valves will strike piston
heads.
lWhen installing chain tensioners or other sliding parts,
lubricate contacting surfaces with new engine oil.
lApply new engine oil to bolt threads and seat surfaces
when installing camshaft sprockets and crankshaft pul-
ley.
lDo not spill engine coolant on drive belts.
UPPER TIMING CHAIN
1. Remove air duct assembly.
2. Remove vacuum hoses, electrical harness connectors and
harness clamps.
3. Remove power steering drive belt.
4. Remove power steering pump and position it to one side.
5. Remove power steering pump bracket.
6. Remove idler pulley and bracket as well.
7. Remove ignition wires and spark plugs.
8. Set No. 1 piston at TDC on its compression stroke.
9. Remove rocker cover.
Remove in numerical order as shown.
10. Remove camshaft sprocket cover.

11. Remove upper chain tensioner.
(Push in piston and insert a suitable pin into the pin hole.)
12. Wipe off the links of the timing chain next to the timing marks
on the sprockets. Put paint marks on the timing chain, match-
ing them with the timing marks on the cam sprockets and
idler sprocket.
13. Remove cam sprocket bolts, cam sprockets and upper tim-
ing chain.
IDLER SPROCKET
1. Remove upper timing chain.
