CAMSHAFT
• 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-11, "Fluids and Lubricants"
• Use procedure below to check for fuel leaks.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leaks
at connection points.
• Start engine. With engine speed increased, check again for fuel leaks at connection points.
• Run engine to check for unusual noise and vibration.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal and 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 make sure there is no leaks of fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec-
ified level, if necessary.
• Summary of the inspection items:
*Power steering fluid, brake fluid, etc.

INSPECTION AFTER REMOVAL
Oil Filter
• Check that there is no foreign material on the oil filter (1) and check
it for clogging.
• Check the oil filter for damage.
• If there is some damage, replace the oil filter, the plug, and the
washer as a set.
CAUTION:
Do not reuse the washer.
Camshaft Runout
1. Put V-block on a precise flat table, and support No. 2 and 5 jour-
nals of camshaft.
CAUTION:
Do not support No. 1 journal (on the side of camshaft
sprocket) because it has a different diameter from the other
four locations.
2. Set a suitable tool vertically to No. 3 journal.
3. Turn camshaft to one direction, and measure the camshaft
runout using suitable tool. (Total indicator reading)

4. If it exceeds the limit, replace camshaft.
Camshaft Cam Height
1. Measure the camshaft cam height using suitable tool (A).
2. If wear exceeds the limit, replace camshaft.
Camshaft Journal Oil Clearance
CAMSHAFT JOURNAL DIAMETER
Measure the outer diameter of camshaft journal using suitable tool
(A).
CAMSHAFT BRACKET INNER DIAMETER
• Tighten camshaft bracket bolts to the specified torque. Refer to "INSTALLATION" for the tightening proce-
dure.
• Measure inner diameter (b) of camshaft bracket using suitable tool
(A).
CAMSHAFT JOURNAL OIL CLEARANCE
• (Oil clearance) = (Camshaft bracket inner diameter) – (Camshaft journal diameter)
• If it exceeds the limit, replace either or both camshaft and cylinder head.
NOTE:
Camshaft brackets cannot be replaced as single parts, because they are machined together with cylinder
head. Replace whole cylinder head assembly.

CAMSHAFT
1. Install camshaft in cylinder head. Refer to
EM-60, "Removal and Installation"
2. Install a suitable tool (A) in thrust direction on front end of cam-
shaft. Measure the camshaft end play using suitable tool when
camshaft is moved forward/backward (in direction of 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:
Do not 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 using suitable tool (A).
(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
.

• Measure the outer diameter of valve lifter using suitable tool (A).
VALVE LIFTER HOLE DIAMETER
Measure the diameter of valve lifter hole of cylinder head using suit-
able tool (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 of Camshaft Sprocket Oil Groove
CAUTION:
• Perform this inspection only when DTC P0011 or P0014 is detected in self-diagnostic results of CON-
SULT and it is directed according to inspection procedure of EC section. Refer to
(P0011) or
• Check when engine is cold so as to prevent burns from the splashing engine oil.
NOTE:
This section provides the inspection method of oil passage of cam sprocket on the intake side. For oil passage
on the exhaust side, the inspection procedure must be changed as instructed below:
1. Check engine oil level. Refer to
.
2. Perform the following procedure so as to prevent the engine from being unintentionally started while
checking.
a. Release the fuel pressure. Refer to
.
b. Remove intake manifold. Refer to
EM-28, "Removal and Installation"

valve hole (A). End crank after checking.
·Step 5
Perform the following inspection if engine oil does not come out from exhaust valve timing control
solenoid valve oil hole of the cylinder head.
• Remove oil filter, and then clean it. Refer to
• Clean oil groove between oil strainer and exhaust valve timing control solenoid valve. Refer to
