Cylinder Head: Removal: Left

WARNING: This page is about a different variant/trim than selected.
CAUTION:

The magnetic timing wheels (1) must not come in contact with magnets (pickup tools, trays, etc.) or any other strong magnetic field. This will destroy the timing wheels ability to correctly relay camshaft position to the camshaft position sensor.

    CAUTION:

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

  35. Rotate the crankshaft clockwise 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.

  36. 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.

  37. Reset the left cam chain tensioner by lifting the pawl (1), pushing back the piston (2) and installing Tensioner Pin (special tool #8514, Pins, Tensioner) (3)

    Refer to VALVE TIMING, STANDARD PROCEDURE .

    NOTE:

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

  38. Install the LH Camshaft Phaser Lock (special tool #10202, Locks, Camshaft/Phaser) (4).
  39. Loosen both the intake oil control valve (6) and exhaust oil control valve (2).
  40. Remove the LH Camshaft Phaser Lock (special tool #10202, Locks, Camshaft/Phaser) (4).
  41. Remove the oil control valve (2) from the left side exhaust cam phaser and pull the phaser off of the camshaft.
  42. Remove the oil control valve (6) from the left side intake cam phaser and pull the phaser off of the camshaft.

    NOTE:

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

  46. Remove the rocker arms. Refer to ROCKER ARM, VALVE  .
    NOTE:

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

  47. If required, remove the hydraulic lifters.
    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.

  48. Using the sequence shown, remove the cylinder head retaining bolts.

    NOTE:

    Right head gasket shown, left head gasket similar.

    WARNING:

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

    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.

    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.

  49. Remove the cylinder head and gasket (1) and discard the gasket.
