1. Warm up engine.
2. Turn ignition switch OFF.
3. Using CONSULT-II, make sure no error codes are indicated forself-diagnosis items. Refer to EC section, ªFuel Pressure
Releaseº.
I Do not disconnect CONSULT-II until the end of this operation;
it will be used to check engine rpm and for error detection at
the end of this operation.
4. Disconnect the negative battery terminal.
5. Remove the following parts.
I Intercooler
I Throttle body
I Rocker cover
6. To prevent fuel from being injected during inspection, remove fuel injection pump fuse [ENG CONT A/T (15A)] from fuse box
on the right side of engine compartment.
7. Remove glow plugs from all the cylinders.
I Before removal, clean the surrounding area to prevent
entry of any foreign materials into the engine.
I Carefully remove glow plugs to prevent any damage or
breakage.
I 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.
:15-19N ×m (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.
I Always use a fully-charged battery to obtain specified
engine speed.
Unit: kPa (bar, kg/cm2, psi)/rpm
Standard MinimumDifference limit between
cylinders
2,942 (29.42, 30.0, 427)/ 200 2,452 (24.52, 25.0, 356)/
200 294 (2.94, 3.0, 43)/200
I
When engine rpm is out of the specified range, check the spe-
cific gravity of battery liquid. Measure again under corrected
conditions.
I If engine rpm exceeds the limit, check valve clearance and
combustion chamber components (valves, valve seats, cylinder
head gaskets, piston rings, pistons, cylinder bores, cylinder
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 A/T (15A)].
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 Diagno-
sis Ð Indexº.

REMOVAL
1. Remove the following parts.
IDrain engine coolant. Refer to MA section, ªChanging Engine
Coolantº.
I Remove engine cover. Refer to the figure at left.
I Remove intercooler.
I Remove air hose (on throttle body side).
I Remove injection tube.
I Remove or relocate wires/harnesses and tubes/pipes.
2. Remove intake manifold in the reverse order of that shown in the figure.
Inspection
Clean surface of intake manifold.
Use a reliable straightedge and feeler gauge to check the flatness
of intake manifold surface. Intake manifold surface flatness:Limit 0.2 mm (0.008 in)
INSTALLATION
1. Tighten intake manifold in the numerical order shown in thefigure.
:25-28N ×m (2.5 - 2.9 kg-m, 18 - 20 ft-lb)
2. Install in the reverse order of removal.
