Valve Timing Verification

SECONDARY TIMING CHAIN VERIFICATION 

Correct timing is critical for the NON free-wheeling designed engine. Engine timing can be verified by using the following procedures:

1. Remove the timing cover. Refer to COVER(S), ENGINE TIMING, REMOVAL AND INSTALLATION  .
2. Remove the spark plugs. Refer to SPARK PLUG, REMOVAL AND INSTALLATION .
3. Place cylinder No. 1 at Top Dead Center (TDC).
   NOTE:

   DO NOT USE THE GREEN REFERENCE MARK ON THE INTAKE AND EXHAUST PHASER TO TIME THE ENGINE 

   NOTE:

   The green line on the intake phaser is only used as a reference to where the intake phaser timing mark is located. The green line on the exhaust phaser is only used as a reference to where the exhaust phaser timing mark is located.

4. Verify that the intake phaser timing mark and the exhaust phaser timing mark alignment with dark colored chain links.
