It prevents the knock pin of the camshaft (INT) from engaging
with the incorrect pin hole when installing the camshaft sprocket
(INT).
9. Remove camshaft sprockets (INT) (1) and (EXH) (2).
Secure hexagonal part (A) of camshaft with a wrench. Loosen
camshaft sprocket bolts and remove camshaft sprocket.
CAUTION:
Never rotate crankshaft or camshaft while timing chain

INSPECTION AFTER INSTALLATION
The following are procedures for checking fluids leak, lubricates leak.
Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to GI-46, "
Recommended Chemical Products and Sealants" .
Use procedure below to check for fuel leakage.
–Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel
leakage at connection points.
–Start engine. With engine speed increased, check again for fuel leakage at connection points.
Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in the guide may
generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after
hydraulic pressure rises.
Warm up engine thoroughly to make sure there is no leakage of fuel, or any oil/fluids including engine oil
and engine coolant.
Bleed air from lines and hoses of applicable lines, such as in cooling system.
After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
Summary of the inspection items:
* Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.
Inspection of Camshaft Sprocket (INT) Oil Groove
CAUTION:
Perform this inspection only when DTC P0011 is detected in self-diagnostic results of CONSULT-II
and it is directed according to inspection procedure of EC section. Refer to EC-47, "
ON BOARD
DIAGNOSTIC (OBD) SYSTEM" .
Check when engine is cold so as to prevent burns from the splashing engine oil.
1. Check engine oil level. Refer to LU-5, "
ENGINE OIL LEVEL" .
2. Perform the following procedure so as to prevent the engine from being unintentionally started while
checking.
a. Remove intake manifold. Refer to EM-18, "

6. Crank engine, and then make sure that engine oil comes out
from intake valve timing control solenoid valve hole (A). End crank after checking.
Check engine oil leakage by oil amount adhered to the waste inserted into the oil hole.
WAR NIN G:
Be careful not to touch rotating parts (drive belts, idler pulley, and crankshaft pulley, etc.).
CAUTION:
Do not perform cranking without installing right engine mount bracket, right engine mount insu-
lator, and right torque rod.
Prevent splashing by using a shop cloth so as to prevent the worker from injury from engine oil
and so as to prevent engine oil contamination.
Prevent splashing by using a shop cloth so as to prevent engine oil from being splashed to
engine and vehicle. Especially, be careful not to apply engine oil to rubber parts of drive belts,
engine mounting insulator, etc. Wipe engine oil off immediately if it is splashed.
7. Perform the following inspection if engine oil does not come out from intake valve timing control solenoid
valve oil hole of the cylinder head.
Remove oil filter (for intake valve timing control), and then clean it. Refer to EM-77, "Components" .
Clean oil groove between oil strainer and intake valve timing control solenoid valve. Refer to LU-4,
"LUBRICATION SYSTEM" .
8. Remove components between intake valve timing control solenoid valve and camshaft sprocket (INT),
and then check each oil groove for clogging.
Clean oil groove if necessary. Refer to LU-4, "LUBRICATION SYSTEM" .

CHECKING COMPRESSION PRESSURE
1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to EC-81, "
FUEL PRESSURE RELEASE" .
3. Disconnect fuel pump fuse (1) to avoid fuel injection during mea-
surement.

Components" .
5. Remove ignition coil and spark plug from each cylinder. Refer to EM-30, "
IGNITION COIL, SPARK PLUG
AND ROCKER COVER" .
6. Connect an engine tachometer (not required in use of CONSULT-II).
7. Install a suitable compression tester with an adapter onto spark
plug hole.
Use the adapter whose picking up end inserted to spark plug
hole is smaller than 20 mm (0.79 in) in diameter. Otherwise, it
may be caught by cylinder head during removal.
8. With accelerator pedal fully depressed, turn ignition switch to “START” for cranking. When the gauge
pointer stabilizes, read the compression pressure and the engine rpm. Perform these steps to check each
cylinder.

Checking Fuel LinesEBS00TSF
Inspect fuel lines, fuel filler cap and fuel tank for improper attach-
ment, leaks, cracks, damage, loose connections, chafing or deterio-
ration.
If necessary, repair or replace damaged parts.
General PrecautionsEBS00TSG
WAR NIN G:
When replacing fuel line parts, be sure to observe the following.
Put a “CAUTION: FLAMMABLE” sign in the work area.
Be sure to work in a well ventilated area and have a CO2 fire extinguisher.
Do not smoke while working on the fuel system. Keep open flames and sparks away from the work
area.
Put drained fuel in an explosion-proof container and put the lid on securely. Keep the container in
safe area.
CAUTION:
Use gasoline required by the regulations for octane number. Refer to GI-6, "Precautions for Fuel
(Unleaded Regular Gasoline Recommended)" .
Before removing fuel line parts, perform the following procedures:
–Release fuel pressure from the fuel lines. Refer to EC-81, "FUEL PRESSURE RELEASE" .
–Disconnect the battery ground cable.
Always replace O-rings and clamps with new ones.
Do not kink or twist tubes when they are being installed.
Perform work on level surface.
Do not tighten hose clamps excessively to avoid damaging hoses.
After connecting fuel tube quick connectors, make sure quick connectors are secure.
Ensure that connector and resin tube do not contact any adjacent parts.
After installing tubes, make sure there is no fuel leakage at connections in the following steps.
–Apply fuel pressure to fuel lines by turning ignition switch ON (without starting the engine). Then
check for fuel leaks at the fuel tube connections.
–Start engine and rev it up and check for fuel leaks at connections.
Use only a genuine NISSAN fuel filler cap as a replacement. If an incorrect fuel filler cap is used,
the MIL may come on.
For servicing “Evaporative Emission System” parts, refer to EC-31, "EVAPORATIVE EMISSION
SYSTEM" .
For servicing "On Board Refueling Vapor Recovery (ORVR)" parts, refer to EC-38, "ON BOARD
