    CAUTION:

    When aligning timing marks, always rotate engine by turning the crankshaft. Failure to do so will result in valve or piston damage.

  10. Rotate the crankshaft CW to place the number one piston at TDC on the exhaust stroke by aligning the dimple (4) on the crankshaft with the block/bearing cap junction (5). The left side cam phaser arrows (2) should point toward each other and be parallel to the valve cover sealing surface (3). The right side cam phaser arrows (7) should point away from each other and the scribe lines (9) should be parallel to the valve cover sealing surface (8).
    CAUTION:

    Always reinstall timing chains so that they maintain the same direction of rotation. Inverting a previously run chain on a previously run sprocket will result in excessive wear to both the chain and sprocket.

  11. Mark the direction of rotation on the timing chain using a paint pen or equivalent to aid in reassembly.

    CAUTION:

    When the timing chains are removed and the cylinder heads are still installed, DO NOT rotate the camshafts or crankshaft without first locating the proper crankshaft position. Failure to do so will result in valve or piston damage.

  12. Reset the RH cam chain tensioner by pushing back the tensioner piston and installing Tensioner Pin (1).

    NOTE:

    Minor rotation of a camshaft (a few degrees) may be required to install the camshaft phaser lock.

  13. Install the RH Camshaft Phaser Lock (5).

    (Special tool #10202, Locks, Camshaft/Phaser)

  14. Loosen both the intake oil control valve (2) and exhaust oil control valve (7).
  15. Remove the RH Camshaft Phaser Lock (5).

    (Special tool #10202, Locks, Camshaft/Phaser)

  16. Remove the oil control valve (2) from the right side intake cam phaser and pull the phaser off of the camshaft.
  17. Remove the oil control valve (7) from the right side exhaust cam phaser and pull the phaser off of the camshaft.

  18. Remove the RH cam chain tensioner arm (6).
  19. Remove two T30 bolts (4) and the RH cam chain tensioner (3).
  20. Remove three T30 bolts (2) and the RH cam chain guide (1).
  21. Remove the right camshafts. Refer to CAMSHAFT, ENGINE, REMOVAL .
    NOTE:

    If the rocker arms and lifters are to be reused, identify their positions so that they can be reassembled into their original locations.

  22. Remove the rocker arms and lifters.
  23. Remove the electric vacuum pump. Refer to PUMP, ELECTRIC VACUUM, REMOVAL .
  24. Remove the support bracket bolts and the support bracket from both cylinder heads.

    CAUTION:

    DO NOT use an impact gun or any type of power tools to break loose or remove the head bolts. This can cause the threads to pull out of the block with the bolts.

  26. Using the sequence shown, remove the cylinder head bolts.

    WARNING:

    The multi-layered steel head gaskets have very sharp edges that could cause personal injury if not handled carefully.

    NOTE:

    The head gasket (1) crimps the locating dowels (2) and the dowels may pull out of the engine block when the head gasket is removed.

  27. Remove the cylinder head and gasket. Discard the gasket.
    CAUTION:

    Do not lay the cylinder head on its gasket sealing surface, due to the design of the cylinder head gasket, any distortion to the cylinder head sealing surface may prevent the gasket from properly sealing resulting in leaks.
