shaft hexagonal part if mounting space is small.

b. Remove the stopper pin and release the plunger to apply ten-

sion to the timing chain.

c. Install the chain tensioner cover onto the front cover.

• Apply liquid gasket as shown.

Use Genuine RTV Silicone Sealant or equivalent. Refer to

7. Check and adjust valve clearances. Refer to

CAMSHAFT

• Perform this inspection only when DTC P0011 is detected in self-diagnostic results of CONSULT III

and it is directed according to inspection procedure of EC section. Refer to

EC-620, "Component

Inspection"

1. Check engine oil level. Refer to

LU-26, "Inspection"

2. Perform the following procedure so as to prevent the engine from being unintentionally started while

checking.

a. Release fuel pressure. Refer to

EC-938, "Fuel Pressure Check"

b. Disconnect ignition coil and injector harness connectors if practical.
3. Remove IVT control solenoid valve.
4. Crank engine, and then make sure that engine oil comes out from IVT control cover oil hole. End cranking

after checking.

WARNING:

Be careful not to touch rotating parts (drive belts, idler pulley, and crankshaft pulley, etc.).

CAUTION:

• Engine oil may squirt from IVT control solenoid valve installation hole 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 components such as drive belts or engine mount insula-

tors. Immediately wipe off any splashed engine oil.

5. Clean oil groove between oil strainer and IVT control solenoid valve if engine oil does not come out from

IVT control valve cover oil hole. Refer to

LU-25, "System Chart"

6. Remove components between IVT control 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.
