•  Plunger stopper tab (C) can be pushed up to release (coaxial structure with lever (B)).

2.  Insert the stopper pin (A) into the tensioner body hole to hold the lever (B) and keep tab released.

   NOTE: Allen wrench [2.5 mm (0.098)] is used for a stopper pin as an example.

3. Insert plunger (C) into tensioner body by pressing timing chain slack guide (1).
4.  Keep timing chain slack (1) guide pressed and hold it by pushing the stopper pin (B) through the lever hole and body hole.
5.  Remove the chain tensioner bolts (A) and chain tensioner.

6. Remove the timing chain from camshaft sprocket (INT) and camshaft sprocket (EXH).

CAUTION:

•  Use suitable tool to prevent timing chain from falling into front cover after it has been removed from camshaft sprocket (INT) and camshaft sprocket (EXH).
•  Do not rotate the crankshaft or camshafts while the timing chain is removed. It can cause damage to the valves and pistons.

Inspection After Installation

Inspection of Camshaft Sprocket (INT) Oil Groove and Camshaft Sprocket (EXH) Oil Groove

WARNING: Check when engine is cold so as to prevent 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.

1.  Check engine oil level and adjust oil level as necessary. Refer to LU-7, "Inspection".
2.  Remove the intake valve timing intermediate lock control solenoid valve, intake valve timing control solenoid valve, and exhaust valve timing control solenoid valve. Refer to EM-74, "Intake Valve Timing Intermediate 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 engine from being unintentionally started while checking.

1.  Release fuel pressure. Refer to EC-144, "Work Procedure".
2.  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 intermediate 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 components such as drive belts or engine mount insulators.

  Immediately wipe off any splashed engine oil.

5. If engine oil does not come out from valve timing control cover oil holes (A), diagnose problem in lubrication 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-5, "Engine Lubrication System".

1.  Remove components between intake valve timing intermediate lock control solenoid valve, intake valve timing control solenoid valve, exhaust valve timing control solenoid valve and camshaft sprocket (INT) or camshaft sprocket (EXH), (if necessary) and then check each oil groove for clogging.
2.  Clean oil groove if necessary. Refer to LU-5, "Engine Lubrication System".

6.  After inspection, install the remaining components in the reverse order of removal
