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.
In cases of removing/installing or replacing camshaft and valve-
related parts, or of unusual engine conditions due to changes in
valve clearance (found malfunctions during stating, idling or causing
noise), perform inspection as follows:
1. Remove rocker covers (right and left bank). Refer to EM-51, "
ROCKER COVER" .
2. Measure the valve clearance as follows:
a. Set No. 1 cylinder at TDC of its compression stroke.
Rotate crankshaft pulley clockwise to align timing mark
(grooved line without color) with timing indicator.
Make sure that intake and exhaust cam nose on No. 1 cylin-
der (engine front side of right bank) are located as shown in
the figure.
If not, turn crankshaft one revolution (360 degrees) and align
as shown in the figure.

Removal and Installation of Front Oil SealNBS004NP
REMOVAL
1. Remove the following parts:
Front engine undercover (power tool)
Drive belts; Refer to EM-15, "DRIVE BELTS" .
Crankshaft pulley; Refer to EM-64, "TIMING CHAIN" .
2. Remove front oil seal using a suitable tool.
CAUTION:
Be careful not to damage front timing chain case and crank-
shaft.
INSTALLATION
1. Apply new engine oil to both oil seal lip and dust seal lip of new front oil seal.
2. Install front oil seal.
Install front oil seal so that each seal lip is oriented as shown
in the figure.
Using a suitable drift, press-fit until the height of front oil seal
is level with the mounting surface.
–Suitable drift: outer diameter 60 mm (2.36 in), inner diameter
50 mm (1.97 in).
Make sure the garter spring is in position and seal lips not
inverted
CAUTION:
Be careful not to damage front timing chain case and
crankshaft.
Press-fit straight and avoid causing burrs or tilting oil
seal.
3. Install in the reverse order of removal after this step.

If the engine speed is out of the specified range, check battery liquid for proper gravity. Check the
engine speed again with normal battery gravity.
If compression pressure is below minimum value, check valve clearances and parts associated with
combustion chamber (valve, valve seat, piston, piston ring, cylinder bore, cylinder head, cylinder head
gasket). After the checking, measure compression pressure again.
If some cylinder has low compression pressure, pour small amount of engine oil into the spark plug hole
of the cylinder to re-check it for compression.
–If the added engine oil improves the compression, piston rings may be worn out or damaged. Check
piston rings and replace if necessary.
–If the compression pressure remains at low level despite the addition of engine oil, valves may be mal-
functioning. Check valves for damage. Replace valve or valve seat accordingly.
If two adjacent cylinders have respectively low compression pressure and their compression remains
low even after the addition of engine oil, cylinder head gaskets are leaking. In such a case, replace cyl-
inder head gaskets.
9. After inspection is completed, install removed parts.
10. Start the engine, and make sure that the engine runs smoothly.
11. Perform trouble diagnosis. If DTC appears, erase it. Refer to EC-100, "
TROUBLE DIAGNOSIS" .

e. Turn all cylinder head bolts 90 degrees clockwise (angle tighten-
ing).
CAUTION:
Check the tightening angle by using the angle wrench
(SST). Avoid judgment by visual inspection without SST.
Check tightening angle indicated on the angle wrench indica-
tor plate.
f. Turn all cylinder head bolts 90 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 measured value is out of the standard, re-install cylinder
head.
5. Install in the reverse order of removal after this step.

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-12, "
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.
Warm up engine thoroughly to make sure there is no leakage of fuel, 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.
Summary of the inspection items:
* Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.

Tighten mounting bolts in two steps in numerical order as
shown in the figure.
6. Connect fuel feed hose on engine side as follows: (Unless otherwise indicated, the installation to the
engine side and centralized under-floor piping side is exactly alike.)
a. Make sure no foreign substances are deposited in and around fuel tube and quick connector, and no dam-
age on them.
b. Thinly apply new engine oil around fuel tube from tip end to spool end.
c. Align center to insert quick connector straightly into fuel tube.
Engine side:
Insert fuel tube into quick connector until top spool is com-
pletely inside quick connector, and 2nd level spool exposes
right below quick connector.
CAUTION:
Hold “A” position as shown in the figure when inserting
fuel tube into quick connector.
Carefully align center to avoid inclined insertion to pre-
vent damage to O-ring inside quick connector.
Insert until you hear a “click” sound and actually feel the
engagement.
To avoid misidentification of engagement with a similar sound, be sure to perform the next step.
Centralized under-floor piping side:
Visually confirm that the two retainer tabs are connected to the connector.
CAUTION:
Carefully align center to avoid inclined insertion to prevent damage to O-ring inside quick con-
nector.
Insert until you hear a “click” sound and actually feel the engagement.
To avoid misidentification of engagement with a similar sound, be sure to perform the next step.
d. Pull quick connector by hand holding position. Make sure it is completely engaged (connected) so that it
does not come out from fuel tube.
e. Install quick connector cap on quick connector connection.
CAUTION:
If cap cannot be installed smoothly, quick connector may
have not been installed correctly. Check connection again.
f. Install fuel feed hose to hose clamps.
7. Install in the reverse order of removal after this step.
