• Using inside micrometer, measure diameter of valve lifter bore of
cylinder head. Refer to EM-247, "Camshaft"
EM-247, "Camshaft".
• If out of the specified range, replace the cylinder head assembly.
Calculation of Valve Lifter Clearance
• (Valve lifter clearance) = (hole diameter for valve li fter) – (outer diameter of valve lifter) Refer to EM-247,
"Camshaft".
• If out of specified range, replace either or both valve lifter and cylinder head assembly.
Inspection after InstallationINFOID:0000000009460570
INSPECTION OF CAMSHAFT SPROCKET (INT) OIL GROOVE
WARNING:
• Check when engine is cold so as to pr event burns from any splashing engine oil.
CAUTION:
• Perform this inspection only when DTC P0011 is detected in self-diagnostic results of CONSULT and
it is directed according to inspection procedure of EC section. Refer to EC-716, "Diagnosis Proce-
dure".
1. Check engine oil level. Refer to MA-26, "ENGINE OIL : Inspection"
.
2. Perform the following procedure so as to prevent the engine from being unintentionally started while
checking.
a. Release fuel pressure. Refer to FL-5, "Inspection"
.
b. Disconnect ignition coil and injector harness connectors if practical.
3. Remove intake valve timing control solenoid valve.
4. Crank engine, and then make sure that engine oil comes out from intake valve timing control solenoid valve cover oil hole.
End cranking after checking.
WARNING:
Be careful not to touch rotating parts (drive belts, idler pul-
ley, and crankshaft pulley, etc.).
CAUTION:
• Engine oil may squirt from intake valve timing control solenoid valve installation hole during cranking. Use a
shop cloth to prevent engi ne oil from splashing on
worker, engine components and vehicle.
• Do not allow engine oil to get on rubber components such
as drive belts or engine mount insulators. I mmediately wipe off any splashed engine oil.
5. Clean oil groove between oil strainer and intake valve timing control solenoid valve if engine oil does not come out from intake valve timing control solenoid valve cover oil hole.
6. Remove components between intake valve timing c ontrol solenoid valve and camshaft sprocket (INT),
and then check each oil groove for clogging.
• Clean oil groove if necessary.
7. After inspection, installation of the remaining components is in the reverse order of removal.
