< REMOVAL AND INSTALLATION >[VQ35DE]
CAMSHAFT
• Using inside micrometer, measure diameter of valve lifter bore of
cylinder head. Refer to EM-247, "Camshaft"
EM-247, "Camshaft".
• If out of the specified range, replace the cylinder head assembly.
Calculation of Valve Lifter Clearance
• (Valve lifter clearance) = (hole diameter for valve li fter) – (outer diameter of valve lifter) Refer to EM-247,
"Camshaft".
• If out of specified range, replace either or both valve lifter and cylinder head assembly.
Inspection after InstallationINFOID:0000000009460570
INSPECTION OF CAMSHAFT SPROCKET (INT) OIL GROOVE
WARNING:
• Check when engine is cold so as to pr event burns from any splashing engine oil.
CAUTION:
• Perform this inspection only when DTC P0011 is detected in self-diagnostic results of CONSULT and
it is directed according to inspection procedure of EC section. Refer to EC-716, "Diagnosis Proce-
dure".
1. Check engine oil level. Refer to MA-26, "ENGINE OIL : Inspection"
.
2. Perform the following procedure so as to prevent the engine from being unintentionally started while
checking.
a. Release fuel pressure. Refer to FL-5, "Inspection"
.
b. Disconnect ignition coil and injector harness connectors if practical.
3. Remove intake valve timing control solenoid valve.
4. Crank engine, and then make sure that engine oil comes out from intake valve timing control solenoid valve cover oil hole.
End cranking after checking.
WARNING:
Be careful not to touch rotating parts (drive belts, idler pul-
ley, and crankshaft pulley, etc.).
CAUTION:
• Engine oil may squirt from intake valve timing control solenoid valve installation hole during cranking. Use a
shop cloth to prevent engi ne oil from splashing on
worker, engine components and vehicle.
• Do not allow engine oil to get on rubber components such
as drive belts or engine mount insulators. I mmediately wipe off any splashed engine oil.
5. Clean oil groove between oil strainer and intake valve timing control solenoid valve if engine oil does not come out from intake valve timing control solenoid valve cover oil hole.
6. Remove components between intake valve timing c ontrol solenoid valve and camshaft sprocket (INT),
and then check each oil groove for clogging.
• Clean oil groove if necessary.
7. After inspection, installation of the remaining components is in the reverse order of removal.

Precaution for Supplemental Restraint System (SRS) "AIR BAG" and "SEAT BELT
PRE-TENSIONER"
INFOID:0000000009951582
The Supplemental Restraint System such as “A IR BAG” and “SEAT BELT PRE-TENSIONER”, used along
with a front seat belt, helps to reduce the risk or severi ty of injury to the driver and front passenger for certain
types of collision. Information necessary to service the system safely is included in the SR and SB section of
this Service Manual.
WARNING:
• To avoid rendering the SRS inopera tive, 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 NISS AN/INFINITI dealer.
• Improper maintenance, including in correct removal and installation of the SRS, can lead to personal
injury caused by unintent ional activation of the system. For re moval of Spiral Cable and Air Bag
Module, see the SR section.
• Do not use electrical test equipmen t on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harn esses can be identified by yellow and/or orange harnesses or har-
ness connectors.
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
• When working near the Airbag Diagnosis Sensor Unit or other Airbag System sensors with the Igni-
tion ON or engine running, DO NOT use air or electri c power tools or strike near the sensor(s) with a
hammer. Heavy vibration could activate the sensor( s) and deploy the air bag(s), possibly causing
serious injury.
• When using air or electric power tools or hammers , always switch the Ignition OFF, disconnect the
battery and wait at least three minutes before performing any service.
General precautions fo r service operationsINFOID:0000000009463538
• Do not work with wet hands.
• The xenon headlamp system includes a high voltage generating
part. Be sure to disconnect batte ry negative cable (negative termi-
nal) or power fuse before removing, installing, or touching the
xenon headlamp (including lamp bulb).
• Turn the lighting switch OFF before disconnecting and connecting the connector.
• When turning the xenon headlamp on and while it is illuminated, do
not touch the harness, bulb, and socket of the headlamp.
• When checking the headlamp on/off operation, check it on vehicle and with the power connected to the vehicle-side connector.
• Do not touch the headlamp bulb glass surface with bare hands or allow oil or grease to get on it. Do not touch the headl amp bulb just after the headlamp is turned off, because
it is very hot.
• Install the xenon headlamp bulb socket co rrectly. If it is installed improperly, high-voltage leak or corona dis-
charge may occur that can melt the bulb, connector or housing. Do not illuminate the xenon headlamp bulb
out of the headlamp housing. Doing so can cause fire and harm your eyes.
• When the bulb has burned out, wrap it in a thick vinyl bag and discard. Do not break the bulb.
• Leaving the bulb removed from the headlamp housing for a long period of time can deteriorate the perfor- mance of the lens and reflector (dirt, clouding). Al ways prepare a new bulb and have it on hand when replac-
ing the bulb.
• When adjusting the headlamp aiming, turn the aiming adjus tment screw only in the tightening direction. If it
is necessary to loosen the screw, first fully loosen the screw, and then turn it in the tightening direction.
• Do not use organic solvent (paint thinner or gasoline) to clean lamps and to remove old sealant.

SERVICE INFORMATION FOR ELECTRICAL INCIDENT
• Do not apply excessive shock to the control unit by dropping or hit-ting it.
• Be careful to prevent condensation in the control unit due to rapid
temperature changes and do not let water or rain get on it. If water
is found in the control unit, dry it fully and then install it in the vehi-
cle.
• Be careful not to let oil to get on the control unit connector.
• Avoid cleaning the control unit with volatile oil.
• Do not disassemble the control unit, and do not remove the upper
and lower covers.
• When using a DMM, be careful not to let test probes get close to each other to prevent the power tr ansistor in the control unit from
damaging battery voltage because of short circuiting.
• When checking input and output signals of the control unit, use the
specified check adapter.
How to Check TerminalINFOID:0000000009463013
CONNECTOR AND TERMINAL PIN KIT
• Use the connector and terminal pin kits listed below when replacing connectors or terminals.
• The connector and terminal pin kits contain some of the most commonly used NISSAN/INFINITI connectors
and terminals. For detailed connector and terminal pin r eplacement procedures, refer to the latest NISSAN/
INFINITI CONNECTOR AND TERMINAL PIN SERVICE MANUAL.

OIL LEVEL
• Before starting the engine, check the oil level. If t
he engine is already started, stop it and allow 10 minutes
before checking.
• Check that the oil level is within the range (A) on the oil level
gauge.
• If it is out of range, add oil as necessary.
ENGINE OIL APPEARANCE
• Check engine oil for white milky appearance or excessive contamination.
• If engine oil becomes milky, it is highly probable t hat it is contaminated with engine coolant. Repair or
replace damaged parts.
OIL LEAKAGE
Check for oil leakage around the following areas:
•Oil pan
• Oil pan drain plug
• Oil pressure switch
• Oil filter
• Oil cooler
• Valve timing control cover and valve timing control solenoid valve
• Front cover
• Mating surface between cylinder block and cylinder head
• Mating surface between cylinder head and rocker cover
• Crankshaft oil seal (front and rear)
OIL PRESSURE CHECK
WARNING:
• Be careful not to burn yoursel f, as engine oil may be hot.
• Put the CVT shift selector in the Park "P" position.
1. Check engine oil level. Refer to OIL LEVEL.
2. Remove fender protector side cover (RH). Refer to EXT-26, "FENDER PROTECTOR : Exploded View"
.
3. Disconnect oil pressure switch harness connector at oil pressure switch. Remove oil pressure switch and install Tools.
CAUTION:
Do not drop or shock oil pressure switch.
4. Start engine and warm it up to normal operating temperature.
5. Check oil pressure with engine running under no-load, using Tool. NOTE:
