INSPECTION AFTER DISASSEMBLY
Surface Distortion

Check the distortion on the mounting surface in the six directions
using a straightedge and a feeler gauge.

If it exceeds the limit, replace exhaust manifold.
TurbochargerEBS00LRJ
CAUTION:
When the compressor wheel turbine, wheel or rotor shaft is damaged, remove all the fragments and
foreign matter left in the following passages in order to prevent a secondary malfunction:
ROTOR SHAFT CLEARANCE

Make sure that the rotor shaft rotates smoothly without any
resistance when it is rotated by your fingertips.

Make sure that the rotor shaft is not loose when it is moved ver-
tically or horizontally.

Measure looseness with a dial indicator inserting its measuring
rod through oil drain hole of turbocharger.

Replace turbocharger if out of standard.Limit : 0.3 mm (0.012 in)

EXHAUST MANIFOLD AND TURBOCHARGER

TROUBLE DIAGNOSIS OF TURBOCHARGER
Preliminary check:

Make sure that the engine oil level is between “MIN” and “MAX” of the oil level gauge. (When engine oil
amount is more than “MAX”, engine oil flows into the inlet duct through blow-by gas passage, and turbo-
charger is misjudged malfunction.)

Ask the customer if he/she always runs the vehicle in idle engine speed to cool the engine oil down after
driving.

Replace the turbocharger assembly when any malfunction is found after unit inspections specified in the
table below.

If no malfunction is found after the unit inspections, judge that the turbocharger body has no malfunction.
Check the other parts again.

c. Install oil pan lower.

Tighten bolts in numerical order as shown in the figure.
8. Install oil pan drain plug.

Refer to figure in EM-157, "Removal and Installation" .
9. Install in the reverse order of removal.
NOTE:
Pour engine oil or start engine at least 30 minutes after oil pan is installed.
INSPECTION AFTER INSTALLATION
1. Check engine oil level and adjust engine oil. Refer to LU-20, "ENGINE OIL" .
2. Check for leakage of engine oil when engine is warmed.
3. Stop engine and wait for 10 minutes.
4. Check engine oil level again. Refer to LU-20, "
ENGINE OIL" .

INJECTION TUBE AND FUEL INJECTOR

CAUTION:

Check gutter spring in nozzle oil seal on fuel injector for missing.
6. Connect injection tubes individually to each cylinder in order of
3-4-1-2.
7. Connect spill hose. Refer to EM-146, "
INTAKE MANIFOLD" .
8. Install remaining parts in the reverse order of removal.
9. Before starting engine, bleed air from fuel piping. Refer to FL-18, "
Air Bleeding" .
INSPECTION AFTER INSTALLATION
Start engine and increase engine speed to check for fuel leak.
CAUTION:
Do not touch engine immediately after stopped as engine becomes extremely hot.
NOTE:
Use mirrors for checking at points out of clear sight.

INSPECTION AFTER REMOVAL
Timing Chain
Check for cracks and excessive wear at roller links. Replace
timing chain if necessary.
INSTALLATION
1. Install new oil seal to spacer.
2. Install spacer to fuel pump.
3. Install coupling to fuel pump of spacer.

Using the TORX wrench (special service tool), tighten the
sprocket nut to fix the coupling.
4. Install adjust shim.

For shim adjustment, measure dimension “L” [Distance
between front surface of coupling and the fuel pump flange
(spacer)] at two opposing points near the coupling bolt center.
Use the average of these two measurements to select the
shim grade that marked on adjust shim.

The shim adjustment is required only when the fuel pump is
replaced.

6. Remove rocker cover gasket.
INSTALLATION
1. Apply 3.0 mm (0.118 in) dia. on locations shown in the figure.

Use Genuine Liquid Gasket or equivalent.
2. Install rocker cover gasket to rocker cover.
3. Tighten holding bolts in numerical order shown in the figure.
Re-tighten to the same torque in the same order as above.
4. Install nozzle oil seal.

Insert it straight until flange fully contacts rocker cover.
5. Install remaining parts in the reverse order of removal.
6. Before starting engine, bleed air from fuel piping. Refer to FL-18, "
Air Bleeding" .
INSPECTION AFTER INSTALLATION
Start engine and increase engine speed to check for fuel leak.

Removal and Installation of Valve Oil SealEBS01FBM
REMOVAL
1. Remove camshafts. Refer toEM-180, "Removal and Installation" .
2. Remove adjusting shims and valve lifters. Refer to EM-180, "
Removal and Installation" .

Check the installation positions, and keep them to avoid being confused.
3. Rotate crankshaft, and set piston whose valve oil seal is to be removed to TDC. This will prevent valve
from dropping into cylinder.
4. Remove valve collet.

Compress the valve spring with valve spring compressor,
attachment and adapter (special service tool). Remove valve
collet with a magnet hand.
CAUTION:
When working, be careful not to damage valve lifter holes.
5. Remove valve spring retainer and valve spring.
6. Remove valve oil seal with the valve oil seal puller (special ser-
vice tool).
INSTALLATION

2. Using the valve oil seal drift (special service tool), install valve oil
seals referring to the dimension shown in the figure.
3. Install in the reverse order of removal.
