Removal and Installation
INFOID:0000000012197432
CAUTION:
All rotation directions indicated in the text are described as seen from engine front.
REMOVAL
1. Remove the following parts.
• Intake manifold: Refer to
EM-197, "Removal and Installation"
.
• Rocker cover: Refer to
EM-214, "Removal and Installation"
• Front cover: Refer to
EM-249, "Removal and Installation"
• Timing chain: Refer to
EM-249, "Removal and Installation"
CAUTION:
Never rotate crankshaft and camshaft separately, for preventing the valve from interfering with
piston during the procedure.
NOTE:
The removal of oil pump drive components is not necessary.
2. Remove the camshaft position sensor and exhaust valve timing position sensor from the camshaft
bracket.
CAUTION:
Never subject parts to impact.
3. Use paint or other means to put matching marks (A) on the cam-
shaft sprocket (INT) (2), camshaft sprocket (EXH) (3), and cam-
shaft bracket (1) as shown in the figure.
NOTE:
This prevents the knock pin of the camshaft from engaging with
the incorrect pin hole when installing the camshaft sprockets.
4. Remove the camshaft sprocket (INT) (1) and the camshaft sprocket (EXH) (2).
• Hold the hexagonal part of the camshaft (A) to fix the camshaft
in place, and then loosen the camshaft sprocket mounting
bolts.
CAUTION:
• After removing the timing chain, never rotate camshaft
and crankshaft individually for prevent valve from inter-
fering with piston.
• Be sure to hold the camshaft hexagonal part so that the
chain tension does not loosen the sprocket mounting
bolts.
5. Remove camshaft bracket according to the following procedure.
a. Loosen bolts in the reverse order of the numerical order shown
in the figure.

b. Pry at the position of the (
) in the figure to cut away the liquid
gasket, and remove the camshaft bracket.
CAUTION:
A liquid gasket more adhesive than previous types is
applied when shipped, so never force it off of a position not
specified.
6. Remove camshaft.
7. Remove valve lifter.
• Identify installation position of each valve. Arrange removed valves so that they cannot be mixed up.
8. If necessary, remove the camshaft signal plates from the camshaft.
INSTALLATION
1. Install valve lifter.
• If reused, install in the original position.
2. Install camshaft.
• Clean the journal to remove any foreign material, dust, and oil.
• Distinguish between the intake and the exhaust by looking at
the different shapes of the front and rear ends of the camshaft
or by using the identification colors (A) and (B).
• Install camshafts to the cylinder head so that knock pin (A) on
front end is positioned as shown in the figure.
NOTE:
The knock pin does not stop at the position facing straight up
due to the camshaft nose location. Therefore, it is generally
acceptable for the position of the knock pin to be almost at the
upper side.
3. Install camshaft bracket according to the following procedure.
a. Remove foreign material completely from the back of camshaft bracket and cylinder head mounting sur-
face.

or equivalent) to the position shown in the figure, while checking
for overlaps.
c. Tighten camshaft bracket bolts evenly in three steps in the order
as shown in the figure.
NOTE:
There are two types of bolts. Refer to the following when install-
ing bolts.
CAUTION:
After tightening the mounting bolts, wipe away any liquid gasket that is squeezed out.
4. Install the camshaft sprocket onto the camshaft according to the following procedure.
a. Refer to the marks (A) that are put when the sprockets are
removed, and securely align the camshaft (INT) knock pins with
the camshaft sprocket (INT) (2) pin holes, and the camshaft
(EXH) knock pins with the camshaft sprocket (EXH) (3) pin
holes, before installing.

Hold the camshaft hexagonal part, and then secure the camshaft.
i.
Tighten the camshaft sprocket mounting bolt.
ii.
Tighten by a further 30
°
(angle tightening).
CAUTION:
Check tightening angle with an angle wrench [SST:
KV10112100 (BT8653-A)] (B) or a protractor. Never estimate
tightening angle visually.
5. Install parts related to the timing chain. Refer to
.
6. Perform inspection and adjustment of valve clearance. Refer to
EM-179, "Inspection and Adjustment"
.
7. Install removed parts in the reverse order of removal.
CAUTION:
When replacing camshaft, remove the 2D code label from the electric throttle control actuator and
clear the valve timing variation value. Refer to
.

INFOID:0000000012197433
INSPECTION AFTER REMOVAL
Camshaft Runout
• Set a pair of V-blocks on a level surface and support journals No. 2 and 5 of camshaft.
CAUTION:
Because journal No. 1 (camshaft sprocket side) has a different diameter from the other four loca-
tions, do not support it.
• Set a dial indicator (A) vertically onto journal No. 3.
• Rotate camshaft one rotation and read indication on the indicator.
• Replace camshaft if the limit is exceeded.
Camshaft Nose Height
• Measure with a micrometer (A).
• Replace camshaft if the value is outside (less than) the limit.

Camshaft bracket inner diameter
• Tighten camshaft bracket bolts to the specified torque.
• Measure inner diameter of the camshaft bracket using a bore
gauge (A).
How to calculate camshaft oil clearance
(Oil clearance ) = (Camshaft bracket inner diameter) - (Camshaft journal outer diameter)
• If the limit is exceeded, replace camshaft and/or cylinder head. Refer to the standards for each unit.
NOTE:
Because camshaft bracket is machined together with cylinder head, replace it as a cylinder head assembly.
Camshaft End Play
• Set a dial indicator (A) to the camshaft front end in thrust direction.
Move the camshaft back and forth (in axial direction) and read indi-
cation on the indicator.

• Refer to the standards above, and then replace camshaft and/or
cylinder head.
Camshaft Sprocket Runout
• Set a pair of V-blocks on a level surface and support journals No. 2 and 5 of camshaft.

tions, do not support it.

• Using an inside micrometer (A), measure the valve lifter hole diam-
eter in cylinder head.
How to calculate valve lifter clearance
• (Clearance) = (Valve lifter hole diameter) - (Valve lifter outer diameter)
• If the value exceeds the standard, replace valve lifter and/or cylinder head. Refer to the standard values for
valve lifter outer diameter and hole diameter.
INSPECTION AFTER INSTALLATION
Inspection of Camshaft Sprocket (INT / EXH) Oil Groove
CAUTION:
• This inspection is performed only when DTC P0011 or P0014 occurs in the CONSULT self-diagnosis
results and when there is also an instruction to do so in the diagnosis procedures of the "Engine
Control System" section. Never perform it at any other time. Refer to
(P0011) and
(P0014).
• Check when engine is cold for preventing burns due to splashed engine oil.
1. Check the engine oil level. Refer to
2. Perform the following procedure for preventing the engine from unintentionally starting during check.
a. Release fuel pressure. Refer to
b. Disconnect the ignition coil and injector harness connectors.
3. Support the bottom of the engine with a transmission jack or an equivalent, and remove the right engine
mount insulator. Refer to
(AWD).
4. Remove the intake and exhaust valve timing control solenoid valves. Refer to
.
NOTE:
Use the supporting jack to slightly raise the front side of the engine.
5. Clean the areas around the valve timing control solenoid valve mounting position, and then insert a clean
shop cloth (without oil) into the oil hole of cylinder head.
6. Under the conditions of step 5, install the engine mount insulator RH. Refer to
(2WD) or
(AWD).
7. Crank engine, and then check that engine oil comes out from cylinder head oil hole (valve timing control
solenoid valve mounting hole).
• The engine oil leakage is judged by the oil amount of the shop cloth inserted into the oil hole.
WARNING:
• Never insert a finger into the oil hole.
• Never touch rotating parts (drive belts, idler pulley, and crankshaft pulley, etc.).
CAUTION:
• Never crank the engine when the engine mount insulator RH is not installed.
• Use shop cloth or other means to prevent engine oil from contacting the engine or vehicle. In
particular, be careful that engine oil does not contact the drive belt, engine mounting insulator,
and other rubber parts. If oil adheres to these parts, wipe it off immediately.
8. Perform the following inspection if engine oil does not come out from the valve timing control solenoid
valve oil hole in the cylinder head.
• Clean the oil passage between the oil strainer (integrated with oil strainer) and valve timing control sole-
