6. Apply reamer finish to valve guide with a valve guide reamer
(commercial service tool).
VALVE SEAT CONTACT

After confirming that the dimensions of valve guides and valves
are within specifications, perform this procedure.

Apply prussian blue (or white lead) onto contacting surface of
valve seat to check the condition of the valve contact on the sur-
face.

Check if the contact area band is continuous all around the cir-
cumference.

If not, grind to adjust valve fitting and check again. If the contact-
ing surface still has NG conditions even after the re-check,
replace valve seat.
VALVE SEAT REPLACEMENT
When valve seat is removed, replace with oversized [0.5 mm (0.020 in)] valve seat.
1. Bore out old seat until it collapses. Boring should not continue beyond the bottom face of the seat recess
in cylinder head. Set the machine depth stop to ensure this. Refer to EM-121, "
Va l v e S e a t" .
2. Ream cylinder head recess diameter for service valve seat.

Be sure to ream in circles concentric to the valve guide center.
This will enable valve seat to fit correctly.
3. Heat cylinder head to 110 to 130°C (230 to 266°F) by soaking in
heated oil.
4. Provide valve seats cooled well with dry ice. Press-fit valve seat into cylinder head.
CAUTION:

Avoid directly to touching cold valve seats.

Cylinder head contains heat, when working, wear protective equipment to avoid getting burned.Standard

CHECKING COMPRESSION PRESSURE
1. Warm up engine thoroughly. Then, stop it.
2. Using CONSULT-II, make sure no error codes are indicated for self-diagnosis items. Refer to EC-1012,
"Basic Inspection" (WITH EURO-ODB) or EC-1382, "Basic Inspection" (WITHOUT EURO-ODB).

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.
3. Disconnect the battery cable from the negative terminal.
4. Remove charge air cooler. Refer to EM-144, "
Removal and Installation"
5. To prevent fuel from being injected during inspection, remove
fuel pump fuse [ENG CONT 2 (20A)] from fuse box on the left
side of engine room.

Among marks on fuse box, [ENG CONT 2 (20A)] is for fuel
pump fuse.
6. Remove glow plugs from all the cylinders. Refer to EM-162,
"Removal and Installation" .
CAUTION:

Before removal, clean the surrounding area to prevent
entry of any foreign materials into engine.

Carefully remove glow plugs to prevent any damage or
breakage.

Handle with care to avoid applying any shock to glow plugs.
7. Install compression gauge adapter (special service tool) to
installation holes of glow plugs and connect compression gauge
for diesel engine.
8. Connect the battery cable to the negative terminal.
9. With accelerator pedal fully depressed, turn ignition switch to
“START” for cranking. When the gauge pointer stabilizes, read
the compression pressure and engine rpm. Perform these steps
to check each cylinder.

Always use a fully-charged battery to obtain specified engine
speed.
Compression pressure
Unit: kPa (bar, kg/cm2 , psi)/rpm

When engine rpm is out of the specified range, check the specific gravity of battery liquid. Measure
again under corrected conditions.

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.

If compression pressure is low in some cylinders, apply engine oil from glow plug installation hole. Then
check pressure again.
–If compression pressure becomes normal after applying engine oil, piston ring may be worn or dam-
aged. Check piston ring for malfunction. If any, replace piston ring.
–If compression pressure is still low after applying engine oil, valve may be malfunctioning. Check valve
for malfunction. If contact malfunction is found, replace valve or valve seat.

If compression pressure in adjacent two cylinders is low after applying engine oil, pressure may be
leaking from gasket. In this case, replace cylinder head gasket.
