INSPECTION AFTER REMOVAL
Oil Filter
• Check that there is no foreign material on the oil filter (1) and check for clogging.
• Check the oil filter for damage.
• If there is damage, replace the oil filter.
Camshaft Runout
1. Put the camshaft on a V-block supporting the No.2 and No.5 journals.
CAUTION:
Do not support the No. 1 journal (on the side of the cam-
shaft sprocket) because it has different diameter from the
other four locations.

on each camshaft sprocket with the painted marks (A) on the
timing chain during removal.
• Before installation of chain tensioner, it is possible to re-match
the painted marks (A) on timing chain with the mating marks
(B) on each sprocket.
CAUTION:
• Aligned mating marks could slip. Therefore, after match-
ing them, hold the timing chain in place by hand.

WARNING:
Check when engine is cold so as to preven t burns from any splashing engine oil.
CAUTION:
Perform this inspection only when DTC P0011, P0014, P052A, P052B is detected in self-diagnostic
results of CONSULT and it is directed according to inspection procedure of EC section. Refer to EC-
210, "Diagnosis Procedure".
1. Check engine oil level and adjust oil level as necessary. Refer to LU-9, "Inspection"
.
2. Remove the intake valve timing intermediate lock control solenoid valve, intake valve timing control sole- noid valve, and exhaust valve timing control solenoid valve. Refer to EM-58, "Intake Valve Timing Interme-
diate Lock Control Solenoid Valve, Intake Valve Timing Control Solenoid Valve, and Exhaust Valve Timing
Control Solenoid Valve".
3. Perform the following procedure to prevent the engi ne from being unintentionally started while checking.
a. Release fuel pressure. Refer to EC-182, "Work Procedure"
.
b. Disconnect injector harness connectors.
4. Crank engine, and then make sure that engine oil comes out of the valve timing control cover oil holes (A). End cranking after
checking.
WARNING:
Be careful not to touch rotating parts (drive belt, crankshaft
pulley, etc.).
CAUTION:
• Engine oil may squirt from intake valve timing intermedi-
ate lock control solenoid valve, intake valve timing control
solenoid valve, exhaust valve timing control solenoid
valve installation holes during cranking. Use a shop cloth
to prevent engine oil from splashing on worker, engine
components and vehicle.
• Do not allow engine oil to get on rubber componen ts such as drive belts or engine mount insula-
tors. Immediately wipe off any splashed engine oil.
5. If engine oil does not come out from valve timing cont rol cover oil holes (A), diagnose problem in lubrica-
tion circuit such as dirty oil groove between oil strainer and intake valve timing intermediate lock control
solenoid valve, intake valve timing control solenoid valve, or exhaust valve timing control solenoid valve.
Refer to LU-7, "Lubrication Circuit"
.
a. Remove components between intake valve timing intermediate lock control solenoid valve, intake valve timing control solenoid valve, exhaust valve timing c ontrol solenoid valve and camshaft sprocket (INT) or
camshaft sprocket (EXH), (if necessary) and then check each oil groove for clogging.
b. Clean oil groove if necessary. Refer to LU-7, "Lubrication Circuit"
.
6. After inspection, install the remaining components in the reverse order of removal.
