INSPECTION
1. CLEAN TOP SURFACES OF PISTONS AND CYL-
INDER BLOCK
(a) Turn the crankshaft, and bring each piston to top dead
center (TDC). Using a gasket scraper, remove all the car-
bon from the piston top surface.
(b) Using a gasket scraper, remove all the gasket material
from the cylinder block surface.
(c) Using compressed air, blow carbon and oil from the bolt
holes.
CAUTION:
Protect your eyes when using high pressure compressed
air.
2. REMOVE GASKET MATERIAL
Using a gasket scraper, remove all the gasket material from the
cylinder block contact surface.
NOTICE:
Be careful not to scratch the cylinder block contact sur-
face.
3. CLEAN COMBUSTION CHAMBERS
Using a wire brush, remove all the carbon from the combustion
chambers.
NOTICE:
Be careful not to scratch the cylinder block contact sur-
face.
4. CLEAN CYLINDER HEADS
Using a soft brush and solvent, thoroughly clean the cylinder
head.

(c) Remove the camshafts.
19. INSPECT CAMSHAFT GEAR BACKLASH
(a) Install the camshafts without installing the exhaust cam
sub-gear  (See page EM-59).
(b) Using a dial indicator, measure the backlash.
Standard backlash:
0.020 - 0.200 mm (0.0008 - 0.0079 in.)
Maximum backlash: 0.30 mm (0.0188 in.)
If the backlash is greater then maximum, replace the cam-
shafts.
(c) Remove the camshafts.
20. INSPECT CAMSHAFT TIMING GEAR (VVT-i)
(a) Mount the hexagon wrench head portion of the camshaft
in a vise.
(b) Check that VVT-i will not turn.
(c) Cover the port except the port on the advance angle side
(nearest to the convex portion) shown in the illustration
with the vinyl tape.
(d) Using the air gun, apply about 100 kPa (1 kgf/cm
3, 14 psi)
of air pressure to the port on the advance side shown in
the illustration.
NOTICE:
When the oil is splashed, wipe it off with a shop lug and the
likes.
HINT:
Perform this in order to release the lock pin for the maximum
delay angle locking.
Standard: Must turn
HINT:
Depending  on the air pressure, VVT-i will turn to the advance
angle side without applying force by hand. Also, under the
condition  that the pressure can be hardly applied because of
the air leakage from the port, there may be the case that the lock
pin could be hardly released.

OIL AND FILTER
INSPECTION
1. CHECK ENGINE OIL QUALITY
Check the oil for deterioration, entry of water, discoloring or thin-
ning.
If the quality is visibly poor, replace the oil.
Oil grade:
API grade SJ, Energy-Conserving or ILSAC multi-
grade engine oil.
SAE  5W  -  30 is the best choice for your vehicle, for
good fuel economy, and good starting in cold weath-
er.
2. CHECK ENGINE OIL LEVEL
After warm up the engine and then 5 minutes after the engine
stop, oil level should be between the low level and full level
marks on the dipstick.
If low, check for leakage and add oil up to the full level mark.
NOTICE:
Do not fill with engine oil above the full level mark.
3. REMOVE OIL PRESSURE SWITCH, AND INSTALL
OIL PRESSURE GAUGE
(a) Using SST, remove the oil pressure switch.
SST 09816-30010
(b) Install the oil pressure gauge.
4. WARM UP ENGINE
Allow the engine to warm up to normal operating temperature.
5. CHECK OIL PRESSURE
Oil pressure:
At idle29 kPa (0.3 kgf/cm2, 4.3 psi) or more
At 3,000 rpm294 - 539 kPa (3.0 - 5.5 kgf/cm2, 43 - 78 psi)

GENERAL MAINTENANCE
These are maintenance and inspection items which are considered to be the owner's responsibility.
They can be done by the owner or they can have them done at a service shop.
These items include those which should be checked on a daily basis, those which, in most cases, do not
require (special) tools and those which are considered to be reasonable for the owner to do.
Items and procedures for general maintenance are as follows.
1. GENERAL NOTES
Maintenance  items may vary from country to country. Check the owner's manual supplement in which
the maintenance schedule is shown.
Every service item in the periodic maintenance schedule must be performed.
Periodic maintenance service must be performed according to whichever interval in the periodic main-
tenance  schedule occurs first, the odometer reading (miles) or the time interval (months).
Maintenance  service after the last period should be performed at the same interval as before unless
otherwise noted.
Failure to do even one item an cause the engine to run poorly and increase exhaust emissions.
2. TIRES
(a) Check the pressure with a gauge. If necessary, adjust.
(b) Check for cuts, damage or excessive wear.
3. WHEEL NUTS
When checking the tires, check the nuts for looseness or for missing nuts. If necessary, tighten them.
4. TIRE ROTATION
Check the owner's manual supplement in which the maintenance schedule is shown.
5. WINDSHIELD WIPER BLADES
Check for wear or cracks whenever they do not wipe clean. If necessary, replace.
6. FLUID LEAKS
(a) Check underneath for leaking fuel, oil, water or other fluid.
(b) If you smell gasoline fumes or notice any leak, have the cause found and corrected.
7. DOORS AND ENGINE HOOD
(a) Check that all doors including the trunk lid operate smoothly, and that all latches lock securely.
(b) Check that the engine hood secondary latch secures the hood from opening when the primary latch
is released.
