CAMSHAFT
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 va
lve lifter outer diameter and valve lifter hole diame-
ter, replace either or both valve lifter and cylinder head.
INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-14, "
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, che ck again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration.
• Warm up engine thoroughly to make sure there is no leakage 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 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-135, "
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-499, "
Inspection".
b. Remove intake manifold. Refer to EM-27, "
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 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 EM-65, "
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".
7. After inspection, installation is in the reverse order of removal.
