• Make sure that there is no foreign material on the oil filter (1) and
check it for clogging.
• Check the oil filter (1) for damage.
• If there is some damage, replace t he oil filter (1), 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:
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.

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 cam shaft sprocket) because it has a different diameter
from the other four locations. Standard: Refer to

• 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-117," Camshaft " .
Valve Lifter Clearance VALVE LIFTER OUTER DIAMETER
Measure the outer diameter of va lve 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.

• 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, che ck 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 de tected in self-diagnostic results of CONSULT-III
and it is directed according to inspect ion procedure of EC section. Refer to EC-133, " Diagnosis Pro-
cedure " .
• Check when engine is cold so as to pr event 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 EC-498, " Inspection " .
b. Remove intake manifold. Refer to EM-28, " Exploded View " .
c. Disconnect ignition coil and injector harness connectors. Refer to EM-46, " Exploded View " .
3. Remove intake valve timing control solenoid valve. Refer to EM-49, " Exploded View " .
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 an d 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 engi ne 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 EM-70, " Inspection " .
• Clean oil groove between oil strainer and intake valve timing control solenoid valve. Refer to LU-6," Engine Lubrication System " and
LU-6, " Engine Lubrication System Schematic " .
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 " and
LU-6, " Engine Lubrica-
tion System Schematic " .

2. Remove valve lifters. Refer to EM-58, " Exploded View " .
3. Rotate crankshaft, and set piston whose valve oil seal is to be removed to TDC. This will prevent valve from dropping into cylinder.
CAUTION:
When rotating crankshaft, be careful to avo id scarring front cover with timing chain.
4. Remove valve collet. • Compress valve spring with Tool (A). Remove valve collet witha magnet hand (B).
CAUTION:
Be careful not to damage valve lifter holes.
5. Remove valve spring retainer, valve spring and valve spring seat. Refer to EM-82, " Disassembly and
Assembly " .
6. Remove valve oil seal with Tool (A).
