CAMSHAFT
Valve Lifter Hole Diameter
●Using inside micrometer, measure diameter of valve lifter hole of
cylinder head.
Calculation of Valve Lifter Clearance
(Valve lifter clearance) = (hole diameter of valve lifter) – (outer diam-
eter of valve lifter).
●When out of specified range, referring to each specification of outer and inner diameter, replace either or
both valve lifter and cylinder head.
Valve ClearanceEBS00LQC
INSPECTION
●The following procedure is applicable when: Components related to camshafts or valves are removed,
installed, or replaced. Drivability concerns (poor starting, poor idling, noise) are caused by valve clearance
aging.
1. Warm up engine, and stop.
2. Remove RH splash cover (integrated with undercover).
3. Remove rocker cover. Refer to EM-29, "
ROCKER COVER" .
4. Turn crankshaft pulley clockwise (viewed from front) to align yel-
low paint with timing indicator.
5. At this point, confirm that both intake and exhaust cam noses on
No. 1 cylinder face outward. (No. 1 cylinder is at TDC of its com-
pression stroke.)
●If not, turn crankshaft pulley more.
NOTE:
Or, valves to be checked when No. 4 cylinder is at TDC of its
compression stroke can be checked first following step 8.
6. Referring to figure, measure valve clearances of valves with × in
table below using a thickness gauge.Standard (Intake and exhaust)
: 30.000 - 30.021 mm (1.1811 - 1.1819 in) dia.
Standard (Intake and exhaust)
: 0.025 - 0.061 mm (0.0010 - 0.0024 in)

Trouble Diagnosis of Turbocharger=NJEM0104S0206Preliminary check:
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.

PRECAUTIONSPFP:00001
Precautions for Supplemental Restraint System (SRS) “AIR BAG” and “SEAT
BELT PRE-TENSIONER”
EBS00K2V
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SRS and SB section of
this Service Manual.
WARNING:
●To 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 per-
formed by an authorized NISSAN/INFINITI dealer.
●Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the SRS section.
●Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harness connec-
tors.
On Board Diagnostic (OBD) System of Engine and A/TEBS00K2W
The ECM has an on board diagnostic system. It will light up the malfunction indicator (MI) to warn the driver of
a malfunction causing emission deterioration.
CAUTION:
●Be sure to turn the ignition switch OFF and disconnect the battery ground cable before any repair
or inspection work. The open/short circuit of related switches, sensors, solenoid valves, etc. will
cause the MI to light up.
●Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MI to light up due to the open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
●Certain systems and components, especially those related to OBD, may use a new style slide-
locking type harness connector. For description and how to disconnect, refer to EL-7.
●Be sure to route and secure the harnesses properly after work. The interference of the harness
with a bracket, etc. may cause the MI to light up due to the short circuit.
●Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MI to light up due to the malfunction of the fuel injection system, etc.
●Be sure to erase the unnecessary malfunction information (repairs completed) from the ECM and
TCM (Transmission control module) before returning the vehicle to the customer.
PrecautionEBS00K2X
●Always use a 12 volt battery as power source.
●Do not attempt to disconnect battery cables while engine is
running.
●Before connecting or disconnecting the ECM harness con-
nector, turn ignition switch OFF and disconnect battery
ground cable. Failure to do so may damage the ECM
because battery voltage is applied to ECM even if ignition
switch is turned off.
●Before removing parts, turn ignition switch OFF and then
disconnect battery ground cable.
