2002 NISSAN TERRANO remove seats

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.
IDo 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.
IIntercooler
IThrottle body
IRocker 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.
IBefore removal, clean the surrounding area to prevent
entry of any foreign materials into the engine.
ICarefully remove glow plugs to prevent any damage or
breakage.
IHandle 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.
IAlways use a fully-charged battery to obtain specified
engine speed.

IWhen engine rpm is out of the specified range, check the spe-
cific gravity of battery liquid. Measure again under corrected
conditions.
IIf 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.

VALVE OIL SEAL
1. Remove timing chain. Refer to EM-26, ªTIMING CHAINº.
2. Remove injection nozzle assembly. Refer to ªInjection Tube and
Injection Nozzleº in ªBASIC SERVICE PROCEDUREº in EC
section.
3. Remove camshaft. Refer to EM-30, ªCAMSHAFTº.
4. Remove valve lifters and mark order No. on each lifter.
5. Replace valve oil seal according to the following procedure.
When replacing valve oil seal, set the corresponding piston at
TDC. Failure to do so causes the valve to drop into the cylin-
der.
1) Set No. 1 cylinder at TDC.
2) Remove valve springs and valve oil seals for No. 1 and No. 4
cylinders. Valve spring seats should not be removed.
3) Install new valve oil seals for No. 1 and No. 4 cylinders as
illustrated. Reinstall valve springs. (pink paint side toward cyl-
inder head)
4) Install valve spring retainers on intake valves and valve rotators
on exhaust valves, and remount valve assembly.
5) Set No. 2 cylinder at TDC.
6) Replace valve oil seals for No. 2 and No. 3 cylinders according
to steps 2) and 3).
7) Install valve lifters in original positions.

5. Remove valve oil seals using valve oil seal puller (SST).
6. Remove valve spring seats.
7. Before removing valve spring seats, perform valve seat contact
check. (Refer to EM-60.)
8. Before removing valve guides, perform valve guide clearance
check. (Refer to below.)
Inspection
CYLINDER HEAD DISTORTION
Using straightedge and feeler gauge, check the bottom of the cyl-
inder head for distortion.
Limit: 0.2 mm (0.008 in)

VALVE GUIDE CLEARANCE
IPerform the inspection before removing valve guides.
ICheck that the valve stem diameter is within specifications.
IPush valve approximately 25 mm (0.98 in) toward combustion
chamber, move valve toward dial indicator to measure valve
movement.
IValve guide clearance is 1/2 of movement on dial indicator.

3. Press service valve guide into cylinder head using suitable tool
until the guide projects out 16 0.2 mm (0.63 0.08 in).
4. Ream valve guide.
Finished size:
8.000 - 8.015 mm (0.3150 - 0.3156 in)
VALVE SEATS
Check valve for any evidence of pitting at valve contact surface,
and reseat or replace if worn out excessively.
IWhen repairing valve seats, check valve and valve guide
for wear beforehand. If worn, replace them. Then correct
valve seat.
IThe cutting should be done with both hands for uniform
cutting.
REPLACING VALVE SEAT FOR SERVICE PARTS
1. Before out old seat until it collapses or remove valve seats with
Tool.
Place a copper seat between contact surface of Tool and cyl-
inder head.
2. Place new valve seats on dry ice and allow them to cool for five
minutes.
WARNING:
Do not touch cooled valve seats with bare hand.
3. Heat cylinder head to 80ÉC (176ÉF).
4. Install cooled valve seats on cylinder head with Tool.
