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.

ancer unit bolt with a new one.
INSTALLATION

2. Install the balancer unit and tighten the bolts in the numerical order as shown:
CAUTION:
• When reusing a bolt, check its outer diameter before installation. Follow the Balan cer Unit Bolt Outer Diameter
procedure.
• Apply new engine oil to threads and seating surfaces of bolts.
• Check tightening angle with an angle wrench (A) or a pro- tractor. Do not make judgme nt by visual check alone.

4. Install timing chain tensioner for balancer unit (1).
• Compress the plunger, insert a stopper pin (A), and then installthe tensioner for the balancer unit.
• Do not pull out ( ) the stopper pin until after installing the tim- ing chain tensioner for balancer unit.
• Check matching mark position of balancer unit drive chain and
each sprocket again.
5. Install camshaft sprockets. • Install them by lining up the mating marks on each camshaft
sprocket (B) with the ones painted on the timing chain (A) dur-
ing removal.
• Before installation of chain tensioner, it is possible to re-match
the marks on timing chain with the ones on each sprocket.
CAUTION:
• Aligned mating marks could slip. Therefore, after match-
ing them, hold the timing chain in place by hand.
• Before and after installing chain tensioner, check again to
make sure that mating marks have not slipped.
6. Install chain tensioner using the following procedure:
a. Install stopper pin (A) into the chain tensioner (1).
b. Install the chain tensioner and pull the stopper pin out. CAUTION:
After installation, pull the stopper pin out, and make sure
that the tensioner is fully released.
7. Install timing chain (1) and related parts. • Install by lining up mating marks on each sprocket and timingchain as shown.
• Before and after installing chain tensioner (3), check to make sure the mating marks have not slipped.
• After installing timing chain tensioner (3), remove the stopper
pin, and make sure that the tensioner moves freely.
CAUTION:
• For the following note, after the mating marks are aligned,
keep them aligned by holding them by hand.
• To avoid skipped teeth, do not move crankshaft and cam- shaft until front cover is installed.
NOTE:
• Before installing chain tensioner (3) it is possible to slip the
chain on the sprocket to align the chain timing mark with the
sprocket timing mark.
• There may be two color variations of the link marks (link col- ors) on the timing chain.
• There are 26 links between the pink mating marks on the tim- ing chain; and 64 links between the camshaft sprocket pink
link and the crankshaft sprocket yellow link, on the timing
chain side without the tensioner.

Use Genuine RTV Silicone Seal ant or equivalent. Refer to
GI-21, "Recommended Chemi cal Products and Sealants"
.
CAUTION:
• For bolt holes with marks (5 locations), apply liquid
gasket outside the holes.
• Installation should be done within 5 minutes after applica-
tion of liquid gasket.
• Do not fill the engine with oil for at least 30 minutes after
the components are installed to allow the liquid gasket to
cure.
c. Make sure the mating marks on the timing chain and each sprocket are still aligned. Then install the front cover.
CAUTION:
Do not damage the front oi l seal during installation.
