Camshaft Cam Lobe Height
1. Measure camshaft cam lobe height as shown. Refer to
EM-247,
"Camshaft".
2. If wear has reduced the lobe height below specifications, replace the camshaft.
Camshaft Journal Clearance
Outer Diameter of Camshaft Journal
• Measure outer diameter of camshaft journal as shown.
Inner Diameter of Camshaft Bracket
1. Tighten camshaft bracket bolt with specified torque.
2. Using inside micrometer, measur e inner diameter (A) of cam-
shaft bearing.
Calculation of Camshaft Journal Clearance
(Journal clearance) = (inner diameter of camshaft br acket) – (outer diameter of camshaft journal)
• When out of the specified range, replac e either or both camshaft and cylinder head.
NOTICE:
Inner diameter of camshaft bracket is manufactur ed together with cylinder head. Replace the whole cylinder
head assembly.
Camshaft End Play
1. Install the camshaft in the cylinder head.

(in direction to axis) as shown.
• If out of the specified range, replace with new camshaft and mea-
sure again.
• If out of the specified range again, replace with new cylinder head.
Camshaft Sprocket Runout
1. Put V-block on precise flat bed and support No. 2 and No. 4 jour- nal of camshaft as shown.
2. Install camshaft sprocket on camshaft.
3. Measure camshaft sprocket runout.
4. If sprocket runout exceeds the limit, replace camshaft sprocket.

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.
