1. Warm up engine sufficiently.
2. Remove spill hoses.
3. Disconnect injection tubes on nozzle side and loosen injection
tubes on pump side. Release clamps on injection tubes.
IUse two wrenches to prevent delivery holder on pump
side from loosening.
4. Remove all injection nozzles using S.S.T. KV119E0030.
5. Turn ignition switch off and disconnect harness connector
(black colored) at injection pump.
6. Fit compression gauge to cylinder head.

7. Crank engine and read compression gauge indication.
Cranking speed: 200 rpm
Compression pressure: kPa (bar, kg/cm
2, psi)
Standard
3,138 (31.4, 32, 455)
Limit
2,452 (24.5, 25, 356)
Limit of difference between cylinders
490 (4.9, 5, 71)
8. If the pressure appears low, pour about 3 m(0.11 Imp fl oz)
of engine oil through nozzle holes and repeat test.
For indications of test, refer to the following table.
Gauge indication during tests Trouble diagnosis
lPiston rings are worn or damaged.
lIf two adjacent cylinders are low, gasket is damaged.
lValve is sticking.
lValve seat or valve contact surface is incorrect.

9. Replace nozzle gaskets and re-install injection nozzles.
New nozzle gaskets must be installed in the direction shown.
Nozzle to cylinder head:
: 54 - 64 N´m (5.5 - 6.5 kg-m, 40 - 47 ft-lb)
10. Install injection tubes using two wrenches as shown.
Injection tubes:
: 22 - 25 N´m (2.2 - 2.5 kg-m, 16 - 18 ft-lb)
11. Install spill hoses.
12. Initialize the ECM.
Refer to EC-section (ªHOW TO ERASE DTCº).

Removal
1. Drain oil.
2. Remove oil pan using tool as illustrated.
1) Insert Tool between oil pan and cylinder block.
IDo not drive seal cutter into oil pump or rear oil seal
retainer portion, or aluminum mating surfaces will be
damaged.
IDo not insert screwdriver, or oil pan flange will be
deformed.
2) Slide Tool by tapping it with a hammer, and remove oil pan.
Installation
1. Before installing oil pan, remove all traces of liquid gasket from
mating surface using a scraper.
IAlso remove traces of liquid gasket from mating surface of
cylinder block.
IBe sure liquid gasket is 3.5 to 4.5 mm (0.138 to 0.177 in) wide.
Use Genuine Liquid Gasket or equivalent.
2. Apply liquid gasket to inner sealing surface as shown at left.

3. Apply liquid gasket to oil pan front oil seal and rear oil seal.
4. Apply a continuous bead of liquid gasket to mating surface of
oil pan.
IAttaching should be done within 5 minutes after coating.
5. Install oil pan and tighten bolts in the order shown in the fig-
ure.
Wait at least 30 minutes before refilling engine oil.
