CAMSHAFT
• 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.

.
3. Remove valve lifters. Refer to EM-210, "Disassembly and Assembly"
.
4. Remove valve collet, valve spring retainer and valve spring using Tool.
CAUTION:
When working, take care not to damage valve lifter holes.
• Compress valve spring using Tool attachment, adapter. Remove valve collet with magnet hand.
5. Remove valve oil seal using Tool.
INSTALLATION
1. Apply new engine oil to new valve oil seal joint surface and seal lip.
2. Press in valve oil seal using Tool to specified height (H).
NOTE:
Height (H): height measured before valve spring seat installa-
tion.
3. Installation of the remaining components is in the reverse order of removal.

2. Remove the crankshaft pulley as follows:
a. Remove the access plate and lock the ring gear using Tool.
CAUTION:
Do not damage the ring gear teeth, or the signal plate teeth behind the ring gear when setting the
stopper.
b. Loosen crankshaft pulley bolt and locate bolt seating surface at 10 mm (0.39 in) from its original position.
c. Position a pulley puller at recess hole of crankshaft pulley to remove crankshaft pulley.
CAUTION:
Do not use a puller claw on crankshaft pulley periphery.
3. Remove front oil seal from front cover using suitable tool. CAUTION:
Be careful not to damage front cover or crankshaft.
INSTALLATION
1. Apply new engine oil to new front oil seal and install.
• Install new front oil seal in the direction as shown.
CAUTION:
• Press fit straight and avoid causing burrs or tilting the
front oil seal.
• Do not reuse front oil seal.
• Press-fit front oil seal until it becomes flush with the timing chain
case end face, using suitable tool.
• Make sure the garter spring in the front oil seal is in position and seal lip is not inverted. Tool number : — (J-50288)
