1. Warm up engine.
2. Turn ignition switch OFF.
3.
Using CONSULT-II, make sure no error codes are indicated for
self-diagnosis items. Refer to EC section, ªFuel Pressure
Releaseº.
+Do not disconnect CONSULT-II until the end of this opera-
tion; it will be used to check engine rpm and for error detec-
tion at the end of this operation.
4. Disconnect the negative battery terminal.
5. Remove the following parts.
+Intercooler cover
+Intercooler
+Throttle body
+Rocker cover
6. To prevent fuel from being injected during inspection, remove
fuel injection pump fuse [ENG CONT (20A)] from fuse box on
the right side of engine compartment.
7. Remove glow plugs from all the cylinders.
+Before removal, clean the surrounding area to prevent
entry of any foreign materials into the engine.
+Carefully remove glow plugs to prevent any damage or
breakage.
+
Handle with care to avoid applying any shock to glow plugs.
8. Install adapter (SST) to installation holes of glow plugs and
connect compression gauge for diesel engine.
:15-19Nzm (1.5 - 2.0 kg-m, 11 - 14 ft-lb)
9. Connect battery negative terminal.
10. Set the ignition switch to ªSTARTº and crank. When gauge
pointer stabilizes, read compression pressure and engine
rpm. Repeat the above steps for each cylinder.
+Always use a fully-charged battery to obtain specified
engine speed.

+When engine rpm is out of the specified range, check the
specific gravity of battery liquid. Measure again under cor-
rected conditions.
+If engine rpm exceeds the limit, check valve clearance and
combustion chamber components (valves, valve seats, cyl-
inder head gaskets, piston rings, pistons, cylinder bores, cyl-
inder block upper and lower surfaces) and measure again.
11. Complete this operation as follows:
a. Turn the ignition switch to ªOFFº.
b. Disconnect battery negative terminal.
c. Replace glow plug oil seals and install glow plugs.
d. Install fuel injection pump fuse [ENG CONT (20A)].
e. Connect battery negative terminal.
f. Using CONSULT-II make sure no error code is indicated for
items of self-diagnosis. Refer to EC section, ªTrouble Diag-
nosis Ð Indexº.

Trouble diagnosis of turbocharger
Preliminary check:
Check that the VNT control valve system has no malfunction.
Refer to EC section, ªECM Terminals and Reference Valueº in
ªTROUBLE DIAGNOSIS Ð GENERAL DESCRIPTIONº.
+Check that the engine oil level is between MIN and MAX of
the dipstick. (When the engine oil amount is more than MAX,
the oil flows into the inlet duct through the blow-by gas
passage, and the turbocharger is misjudged failure.)
+Ask the customer if he/she always runs the vehicle in idle
engine speed to cool the 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 failure. Check the other parts
again.

follows.
Adjustments
+Remove the adjusting shim for parts which are outside the
specified valve clearance.
1. Remove the spill tube.
2. Extract the engine oil on the upper side of the cylinder head
(for the air gun used in step 7).
3. Rotate the crankshaft to face the cam for adjusting shims that
are to be removed upward.
4. Grip the camshaft with camshaft pliers (SST), the using the
camshaft as a support point, push the adjusting shim down-
ward to compress the valve spring.
CAUTION:
Do not damage the camshaft, cylinder head, or the outer
circumference of the valve lifter.
5. With the valve spring in a compressed state, remove the
camshaft pliers (SST) by securely setting the outer circum-
ference of the valve lifter with the end of the lifter stopper
(SST).
+Hold the lifter stopper by hand until the shim is removed.
CAUTION:
Do not retrieve the camshaft pliers forcefully, as the cam-
shaft will be damaged.
6. Move the rounded hole of the adjusting shim to the front with
a very thin screwdriver.
+When the adjusting shim on the valve lifter will not rotate
smoothly, restart from step 4 with the end of the lifter stop-
per (SST) touching the adjusting shim.
7. Remove the adjusting shim from the valve lifter by blowing
air through the rounded hole of the shim with an air gun.
CAUTION:
To prevent any remaining oil from being blown around, thor-
oughly wipe the area clean and wear protective goggles.
