2009 NISSAN LATIO warning

Component " .
6. Crank engine, and then make sure that engine oil comes out from intake valve timing control solenoid valve hole (A). End cranking after checking.
• Check engine oil leakage by oil amount adhered to the shop cloth inserted into the oil hole.
WARNING:
• Be careful not to touch rotating parts (drive be lts, idler pulley, and crankshaft pulley, etc.).
• Prevent splashing by using a shop cloth so as to prevent the worker from injury from engine oil
and so as to prevent engi ne oil contamination.
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 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.
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-199, " Component " .
• Clean oil groove between oil strainer and intake valve timing control solenoid valve. Refer to LU-15 .
8. 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. Refer to LU-15 .
9. Installation of the remaining components is in the reverse order of removal
Valve Clearance INFOID:0000000004307146
INSPECTION
Perform inspection as follows after removal, installation or replacement of camshaft or valve-related parts, or if
there is unusual engine conditions regarding valve clearance.
1. Remove rocker cover. Refer to EM-153 .
2. Measure the valve clearance with the following procedure:
a. Set No. 1 cylinder at TDC of its compression stroke. • Rotate crankshaft pulley (1) clockwise and align TDC mark (no paint) (B) to timing indicator (A) on front
cover. 1 : Front cover

Measure the diameter of valv
e stem with a micrometer (A).
Valve Guide Inner Diameter Measure the inner diameter of valve guide with a bore gauge.
Valve Guide Clearance (Valve guide clearance) = (Valve guide inner diameter) – (Valve stem diameter).
• If it exceeds the limit, replace valve guide and/or valve.
VALVE GUIDE REPLACEMENT When valve guide is removed, replace with oversized [0.2 mm (0.008 in)] valve guide.
1. To remove valve guide, heat cylinder head to 110 ° to 130 °C
(230 ° to 266 °F) by soaking in heated oil (A).
2. Drive out valve guide using suitable tools. WARNING:
Cylinder head contai ns heat, when workin g, wear protective
equipment to avoid getting burned. Standard
Intake : 5.465 - 5.480 mm (0.2152 - 0.2157 in)

3. Ream cylinder head valve guide hole using suitable tool (A).
4. Heat cylinder head to 110 ° to 130 °C (230 ° to 266 °F) by soaking
in heated oil (A).
5. Press valve guide (1) from camshaft side to dimensions as shown.
WARNING:
Cylinder head contains heat, when working, wear protective
equipment to avoid getting burned.
6. Apply reamer finish to valve guide using suitable tool (A).
VALVE SEAT CONTACT
• After confirming that the dimensions of valve guides and valves are within specifications, perform this proce-
dure.
• Apply prussian blue (or white lead) onto contacting surfac e of valve seat to check the condition of the valve
contact on the surface. Valve guide hole diameter (for service parts):
: 9.675 - 9.696 mm (0.3809 - 0.3817 in) PBIC3215J

• Check if the contact area band is continuous all around the circum-
ference.
• If not, grind to adjust valve fitti ng and check again. If the contacting
surface still has NG conditions even after the re-check, replace
valve seat.
VALVE SEAT REPLACEMENT When valve seat is removed, replace with oversized [0.5 mm (0.020 in)] valve seat.
1. Bore out old seat until it collapses. Boring shoul d not continue beyond the bottom face of the seat recess
in cylinder head. Set the machine depth stop to ensure this. Refer to EM-227, " Standard and Limit " .
2. Ream cylinder head (1) recess diameter for service valve seat.
• Be sure to ream in circles concentric to the valve guide center.This will enable valve seat to fit correctly.
3. Heat cylinder head to 110 ° to 130 °C (230 ° to 266 °F) by soaking
in heated oil (A).
4. Provide valve seats cooled well with dry ic e. Press-fit valve seat into cylinder head.
WARNING:
• Never touch cold valve seats directly.
• Cylinder head contains heat, wh en working, wear protective equipment to avoid getting burned.
5. Using valve seat cutter set or valve seat grinder, finish valve seat to the specified dimensions. For dimensions, refer to EM-227, " Standard and Limit " .
CAUTION:
When using valve seat cutter, firmly grip the cutter handle
with both hands. Then, press on the contacting surface all
around the circumference to cu t in a single drive. Improper
pressure on the cutter or cutting many different times may
result in staged valve seat.
6. Using compound, grind to adjust valve fitting.
7. Check again for normal contact. SBIA0322E
