CAMSHAFT

1.

Install camshaft in cylinder head. Refer to 

EM-53, "Removal and Installation"

 for tightening procedure.

2.

Install a dial indicator (A) in thrust direction on front end of cam-
shaft. Measure the camshaft end play on the dial indicator when
camshaft is moved forward/backward (in direction to axis).

• Measure the following parts if out of the standard.
- Dimension “A” for cylinder head No. 1 journal bearing

- Dimension “B” for camshaft thrust

• 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.

2.

Measure the camshaft sprocket runout with a dial indicator.
(Total indicator reading)

• If it exceeds the limit, replace camshaft sprocket.

Valve Lifter 

Check if surface of valve lifter has any wear or cracks.
• If anything above is found, replace valve lifter. Refer to 

EM-93,

"Camshaft"

.

• Measure the outer diameter of valve lifter with a micrometer (A).

VALVE LIFTER HOLE DIAMETER
Measure the diameter of valve lifter hole of cylinder head with an
inside micrometer (A).

VALVE LIFTER CLEARANCE
• (Valve lifter clearance) = (Valve lifter hole diameter) – (Valve lifter outer diameter)

• If out of the standard, referring to the each standard of valve lifter outer diameter and valve lifter hole diame-

ter, replace either or both valve lifter and cylinder head.

INSPECTION AFTER INSTALLATION

Inspection for Leaks

The following are procedures for checking fluids leak, lubricates 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-8, "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 leak-

age 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.

NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal/installation, slack in the guide may
generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after
hydraulic pressure rises.

• Warm up engine thoroughly to check there is no leakage of fuel, 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.

Inspection of Camshaft Sprocket (INT) Oil Groove

CAUTION:

• Perform this inspection only when DTC P0011 is detected in self-diagnostic results of CONSULT-III

and it is directed according to inspection procedure of EC section. Refer to 

EC-127, "DTC Logic"

.

• Check when engine is cold so as to prevent burns from the splashing engine oil.

1.

Check engine oil level. Refer to 

LU-7, "Inspection"

.

2.

Perform the following procedure so as to prevent the engine from being unintentionally started while
checking.

a.

Release the fuel pressure. Refer to following;
• HR12DE (TYPE 1): 

EC-113, "Work Procedure"

• HR12DE (TYPE 2): 

EC-386, "Work Procedure"

b.

Remove intake manifold. Refer to 

EM-29, "WITH EGR CONTROL VALVE : Exploded View"

.

c.

Disconnect ignition coil and injector harness connectors. Refer to 

EM-41, "Exploded View"

.

3.

Remove intake valve timing control solenoid valve. Refer to 

EM-53, "Exploded View"

.

4.

Crank engine, and then check that engine oil comes out from
intake valve timing control solenoid valve hole (A). End crank
after checking.

WARNING:

Be careful not to touch rotating parts (drive belts, idler pul-
ley, and crankshaft pulley, etc.).

CAUTION:

• 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.

5.

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, and then clean it. Refer to 

LU-10, "Removal and Installation"

.

• Clean oil groove between oil strainer and intake valve timing control solenoid valve. Refer to 

LU-6,

"Engine Lubrication System"

.

6.

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-6, "Engine Lubrication System"

.

7.

After inspection, install removed parts in the reverse order.
