FRONT TIMING CHAIN CASE
Revision: 2006 November2007 350Z

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 exhaust gases, 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.

INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases 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 MA-11, "
RECOMMENDED 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
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.

4. Crank the engine, and then make sure that engine oil comes out
from valve timing control solenoid valve hole. End crank 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 sole-
noid valve installation hole during cranking. Use a shop
cloth to prevent the engine components and the vehicle. Do not allow engine oil to get on rubber
components such as drive belt or engine mount insulators. Immediately wipe off any splashed
engine oil.

Clean oil groove between oil strainer and intake valve timing control solenoid valve if engine oil does not
come out from valve timing control solenoid valve hole. Refer to LU-4, "
LUBRICATION SYSTEM" .
5. 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" .
6. After inspection, install removed parts.

e. Turn all bolts 95 degrees clockwise (angle tightening).
CAUTION:
Check the tightening angle by using angle wrench (SST).
Avoid judgment by visual inspection without tool.

Check tightening angle indicated on angle wrench (SST) indi-
cator plate.
f. Turn all bolts 95 degrees clockwise again (angle tightening).
4. After installing cylinder head, measure distance between front
end faces of cylinder block and cylinder head (left and right
banks).

If the measured value is out of the standard, re-install cylinder
head.
5. Install in the reverse order of removal after this step.
