7. Remove camshaft position sensor (PHASE) from camshaft bracket.
CAUTION:
 Handle carefully to avoid dropping and shocks.
 Never disassemble.
 Never allow metal powder to adhere to magnetic part at sensor tip.
 Never place sensor in a location where it is exposed to magnetism.
8. Put the matching mark (A) on the camshaft sprocket (INT) (2)
and the camshaft bracket (1) as shown.
NOTE:
It prevents the knock pin of the camshaft (INT) from engaging
with the incorrect pin hole when installing the camshaft sprocket
(INT).
9. Remove camshaft sprockets (INT) (1) and (EXH) (2).
 Secure hexagonal part (A) of camshaft with a wrench. Loosen
camshaft sprocket bolts and remove camshaft sprocket.
CAUTION:
 Never rotate crankshaft or camshaft while timing chain
is removed. It causes interference between valve and
piston.
 Never loosen the bolts with securing anything other
than the camshaft hexagonal part or with tensioning the
timing chain.
10. Loosen bolts in reverse order as shown.
11. Cut liquid gasket by prying the position ( ) shown, and then
remove the camshaft bracket.
CAUTION:
 Be careful not to damage the mating surface.
 A more adhesive liquid gasket is applied compared to pre-
vious types when shipped, so it should not be forced off
the position not specified.
12. Remove camshafts.

 Measure the inner diameter of camshaft bracket with a bore gauge
(A).
CAMSHAFT JOURNAL OIL CLEARANCE
 (Oil clearance) = (Camshaft bracket inner diameter) – (Camshaft journal diameter)
 If it exceeds the limit, replace camshaft or cylinder head, or both.
NOTE:
Camshaft bracket cannot be replaced as a single part, because it is machined together with cylinder head.
Replace whole cylinder head assembly.
Camshaft End Play
1. Install camshaft in cylinder head.
2. Install dial indicator in thrust direction on front end of camshaft.
Read the end play of dial indicator (A) when camshaft is moved
forward/backward (in direction to axis).
 Measure the following parts if out of the standard.
- Dimension “A” for groove of cylinder head No. 1 journal
- Dimension “B” for camshaft flange
 Refer to the standards above, and then replace camshaft and/
or cylinder head.
Camshaft Sprocket Runout
1. Put V-block on precise flat table, and support No. 2 and 5 journals of camshaft.
CAUTION:
Never support No. 1 journal (on the side of camshaft sprocket) because it has a different diameter
from the other four locations.
B : Measuring direction of inner diameter
Standard:
No. 1 : 28.000 - 28.021 mm (1.1024 - 1.1032 in)

 Clean camshaft journal to remove any foreign material.
 Distinguish between the intake and the exhaust by looking at
the different shapes of the front and rear ends of the camshaft
or using the identification colors (A) and (B).
 Install camshafts so that camshaft dowel pins (A) on the front
side are positioned as shown.
NOTE:
Though camshaft does not stop at the positions as shown, for
the placement of cam nose, it is generally accepted camshaft
is placed for the same direction as shown.
3. Remove foreign material completely from camshaft bracket backside and from cylinder head installation
face.
4. Apply liquid gasket (A) to camshaft bracket as shown.
Use Genuine Silicone RTV Sealant or equivalent. Refer to

5. Install camshaft bracket bolts in three stage in numerical order
as shown in numerical order as shown.
 There are two types of bolts. Refer to the following for locating
bolts.
6. Tighten all bolts in numerical order in three steps.
7. Install the camshaft sprocket (INT) to the camshaft (INT).
NOTE:
When the camshaft sprocket (INT) (2) is removed, refer to the
paint mark (A) put according to step “3”. Securely align the
knock pin and the pin hole, and then install them.
8. Tighten camshaft (INT) sprocket bolt.
NOTE:
Secure the hexagonal part of camshaft (INT) using wrench to tighten bolt.
9. Turn 67 degrees clockwise (angle tightening) using Tool.
CAUTION:
Never judge by visual inspection without an angle wrench.

4. Clean the mating area of intake valve timing control solenoid
valve. Insert a clean shop cloth (with no oil adhesion) into the oil
hole (A) of the cylinder head.
5. Install engine mounting bracket (RH), engine mounting insulator,
and torque rod (RH) under the Step 4 condition. (With intake
valve timing control solenoid valve removed, and a shop cloth
inserted into the oil hole.) Refer to EM-207, "
Component".
6. Crank engine, and then make sure that engine oil comes out
from intake valve timing control solenoid valve hole (A). End crank after checking.
 Check engine oil leakage by oil amount adhered to the waste inserted into the oil hole.
WARNING:
Be careful not to touch rotating parts (drive belts, idler pulley, and crankshaft pulley, etc.).
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 the worker from injury from engine oil
and so as to prevent engine oil contamination.
 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 engine 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-186, "
Component".
 Clean oil groove between oil strainer and intake valve timing control solenoid valve. Refer to LU-11,
"Lubrication Circuit".
8. 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-11, "
Lubrication Circuit".
