a. Release fuel pressure. Refer to
EC-665, "Fuel Pressure Check".
b. Disconnect ignition coil and injector harness connectors.
3. Remove intake valve timing control solenoid valve. Refer to EM-199, "
Component".
4. Crank the engine, and then make sure that engine oil comes out from intake valve timing control cover oil hole. End crank after
checking.
WARNING:
Be careful not to touch rotati ng parts (drive belt, 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 co mponents 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 intake valve timing control cover oil hole. Refer to LU-21, "
Lubrication Circuit".
5. 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-21, "
Lubrication Circuit".
6. After inspection, install removed parts.
Valve ClearanceINFOID:0000000001325792
INSPECTION
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 dur ing starting, idling or causing noise), perform
inspection as follows:
1. Remove rocker covers (right and left bank). Refer to EM-196, "
Component".
2. Measure the valve clearance as follows:
a. Set No. 1 cylinder at TDC of its compression stroke.  Rotate crankshaft pulley in clockwise to align TDC identifica-
tion notch (without paint mark) with timing indicator on front
cover.
 Make sure that both intake and exhaust cam noses of No. 1 cylinder (engine front side of left bank) are located as shown in
the figure.
 If not, turn crankshaft one revolution (360 degrees) and align
as shown in the figure.

CUSTOMER INTERVIEW
Interview the customer if possible, to determine the conditions thatexist when the noise occurs. Use the Diag-
nostic Worksheet during the interviewto document t he facts and conditions when the noise occurs and any
customer'scomments; refer to GW-9, "
Diagnostic Worksheet". This information is necessary to duplicate the
conditions that existwhen the noise occurs.
 The customer may not be able to provide a detailed descriptionor the location of the noise. Attempt to obtain all the facts and conditionsthat exist w hen the noise occurs (or does not occur).
 If there is more than one noise in the vehicle, be sure to diagnoseand repair the noise that the customer is
concerned about. This can be accomplishedby test driving the vehicle with the customer.
 After identifying the type of noise, isolate the noise in terms of its characteristics. The noise characteristics
are provided so the customer, service adviser and technician are all speaking the same language when
defining the noise.
 Squeak —(Like tennis shoes on a clean floor)
Squeak characteristics include the light contact/fa st movement/broughton by road conditions/hard sur-
faces=higher pitch noise/softer surfaces=l owerpitch noises/edge to surface=chirping
 Creak—(Like walking on an old wooden floor)
Creak characteristics include firm contact/slow mo vement/twisting witha rotational movement/pitch depen-
dent on materials/often brought on by activity.
 Rattle—(Like shaking a baby rattle)
Rattle characteristics include the fast repeated contac t/vibration orsimilar movement/loose parts/missing clip
or fastener/incorrect clearance.
 Knock —(Like a knock on a door)
Knock characteristics include hollow sounding/some times repeating/oftenbrought on by driver action.
 Tick—(Like a clock second hand) Tick characteristics include gentle contacting of li ght materials/loosecomponents/can be caused by driver
action or road conditions.
 Thump—(Heavy, muffled knock noise) Thump characteristics include softer k nock/dead sound often brought on by activity.
 Buzz—(Like a bumble bee)
Buzz characteristics include high frequency rattle/firm contact.
 Often the degree of acceptable noise level will vary dependingupon the person. A noise that you may judge as acceptable may be very irritatingto the customer.
 Weather conditions, especially humidity and temper ature, may havea great effect on noise level.
DUPLICATE THE NOISE AND TEST DRIVE
If possible, drive the vehicle with the customer until the noise isduplicated. Note any additional information on
the Diagnostic Worksheet regardingthe conditions or location of the noise. This information can be used to
duplicatethe same conditions when you confirm the repair.
