CAMSHAFT
• Make sure 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.
Camshaft Runout
1.
Put V-block on a precise flat table, and support No. 2 and 5 jour-
nals 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.
Set a dial indicator vertically to No. 3 journal.
3.
Turn camshaft to one direction with hands, and measure the
camshaft runout on the dial indicator. (Total indicator reading)
4.
If it exceeds the limit, replace camshaft.
Camshaft Cam Height
1.
Measure the camshaft cam height with a micrometer (A).
2.
If wear exceeds the limit, replace camshaft.
Camshaft Journal Oil Clearance
CAMSHAFT JOURNAL DIAMETER
Measure the outer diameter of camshaft journal with a micrometer
(A).
CAMSHAFT BRACKET INNER DIAMETER
• Tighten camshaft bracket bolts with the specified torque. Refer to
EM-59, "Removal and Installation"
.

• Measure inner diameter (B) 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 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 End Play
1.
Install camshaft in cylinder head. Refer to
EM-59, "Removal and Installation"
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
• Follow 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.

CAMSHAFT
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
.
Valve Lifter Clearance
VALVE LIFTER OUTER DIAMETER
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 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-19, "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 make sure 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.
Summary of the inspection items:
*: Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.
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
• Check when engine is cold so as to prevent burns from the splashing engine oil.
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
(EURO-OBD),
EURO-OBD).
b.
Remove intake manifold. Refer to
c.
Disconnect ignition coil and injector harness connectors. Refer to
.
3.
Remove intake valve timing control solenoid valve. Refer to
4.
Crank engine, and then make sure 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.
