VALVE OIL SEAL
1. Remove both timing belts.
2. Remove camshaft sprockets and back covers.
3. Remove camshaft brackets by loosening bracket nuts from
center to outside in two or three stages.
4. Remove camshaft oil seals and camshaft.
5. Remove valve lifters and mark order No. on each lifter.
6. 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. (Narrow pitch side toward
cylinder head)
4) Install valve spring retainers on intake valves and valve rota-
tors 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 accord-
ing to steps 2) and 3).
7) Install valve lifters in original positions.
CAMSHAFT AND CRANKSHAFT OIL SEAL INSTALLING

remove radiator.
8. Disconnect fuel tubes and vacuum tubes.
9. Release power steering belt adjusting nut and remove power
steering pump from engine.
Bind pump properly to the vehicle.
10. Remove A/C compressor.
11. Disconnect or remove electrical wiring where necessary.
12. Release clutch lever cable.
13. Release tachometer cable from transaxle housing.
14. Remove front wheels.
15. Remove brake caliper mounting bolts and bind caliper properly
to vehicle LH & RH.

Observe the following precautions to ensure safe and
proper servicing.
Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
The Supplemental Restraint System ªAir Bagº and ªSeat Belt
Pre-tensionerº, used along with a seat belt, help to reduce the
risk or severity of injury to the driver and front passenger in a
frontal collision. The Supplemental Restraint System consists of
air bag modules (located in the center of the steering wheel and
on the instrument panel on the passenger side), seat belt pre-
tensioners, a diagnosis sensor unit, warning lamp, wiring har-
ness and spiral cable.
If the vehicle is equipped with side air bag as the Supplemental
Restraint System, the side air bag used along with the seat belt
helps to reduce the risk or severity of injury to the driver and front
passenger in a side collision. The side air bag consists of air bag
modules (located in the outer side of front seats), satellite sensor,
diagnosis sensor unit (which is one of components of air bags for
a frontal collision), wiring harness, warning lamp (which is one of
components of air bags for a frontal collision).
WARNING:
lTo avoid rendering the SRS inoperative, (which could
increase the risk of personal injury or death in the event
of a collision which would result in air bag inflation) all
maintenance must be performed by an authorized
NISSAN dealer.
lImproper maintenance, including incorrect removal and
installation of the SRS, can lead to personal injury
caused by unintentional activation of the system.
lDo not use electrical test equipment on any circuit
related to the SRS unless instructed to do so in this
Service Manual. SRS wiring harnesses are covered with
yellow insulation (either just before the harness connec-
tors or for the complete harness), for easy identification.
Precautions for NATS
NATS (Nissan Anti-Theft System)
NATS will immobilize the engine if someone tries to start it with-
out the registered key of NATS.
Both of the originally supplied ignition key IDs have been NATS
registered.
The NATS security indicator is located on the instrument panel.
The indicator flashes when the ignition switch is in ªLOCKº or
ªAccº position. Therefore, NATS warns outsiders that the vehicle
is equipped with the anti-theft system.
lWhen NATS detects trouble, the malfunction indicator (MI)
flashes.
This flashing indicates that the anti-theft is not functioning, so
prompt service is required.
lWhen servicing NATS (trouble diagnoses, system initialisa-
tion and additional registration of other NATS ignition key
IDs), CONSULT-II hardware and CONSULT-II NATS soft-
ware is necessary.
