NISSAN TIIDA 2009 Service Repair Manual

Fluids and Lubricants " .
• 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 leak-
age at connection points.
- Start engine. With engine speed increased, che ck 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 de tected in self-diagnostic results of CONSULT-III
and it is directed according to inspect ion procedure of EC section. Refer to EC-133, " Diagnosis Pro-
cedure " .
• Check when engine is cold so as to pr event burns from the splashing engine oil.
1. Check engine oil level. Refer to LU-7, " Inspection " .
2. Perform the following procedure so as to prevent the engine from being unintentionally started while
checking.
a. Release the fuel pressure. Refer to EC-498, " Inspection " .
b. Remove intake manifold. Refer to EM-28, " Exploded View " .
c. Disconnect ignition coil and injector harness connectors. Refer to EM-46, " Exploded View " .
3. Remove intake valve timing control solenoid valve. Refer to EM-49, " Exploded View " .
4. Crank engine, and then make sure that engine oil comes out from intake valve timing control solenoid valve hole (A). End
crank after checking.
WARNING:
Be careful not to touch rotating parts (drive belts, idler pul-
ley, and crankshaft pulley, etc.).
CAUTION:
• Prevent splashing by using a shop cloth so as to prevent
the worker from injury from engine oil an d 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 engi ne oil off immediately if it is splashed.

5. 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, and then clean it. Refer to EM-70, " Inspection " .
• Clean oil groove between oil strainer and intake valve timing control solenoid valve. Refer to LU-6," Engine Lubrication System " and
LU-6, " Engine Lubrication System Schematic " .
6. 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-6, " Engine Lubrication System " and
LU-6, " Engine Lubrica-
tion System Schematic " .
7. After inspection, installation is in the reverse order of removal.

Exploded View " .
2. Remove valve lifters. Refer to EM-58, " Exploded View " .

4. Remove valve collet. • Compress valve spring with Tool (A). Remove valve collet witha magnet hand (B).
CAUTION:
Be careful not to damage valve lifter holes.
5. Remove valve spring retainer, valve spring and valve spring seat. Refer to EM-82, " Disassembly and
Assembly " .
6. Remove valve oil seal with Tool (A).
INSTALLATION
1. Apply new engine oil to valve oil seal joint surface and seal lip.
2. Press in valve oil seal to the height “H” shown with Tool (A).
