ISSUE:

Some vehicles equipped with 4.6L, 5.4L, and 6.8L 3-valve engines built between 1/11/2006 and 2/14/2006 may exhibit a loud ticking noise in the valve train area. This may be caused by a stuck/collapsed lash adjuster.

ACTION:

Verify engine build date, isolate, and replace any stuck/collapsed lash adjuster by following the Service Procedure.

SERVICE PROCEDURE

  1. Check date code on the engine, located on the engine timing cover.
    1. Date code between 1/11/2006 and 2/14/2006, proceed to Step 2.
    2. Date code NOT between 1/11/2006 and 2/14/2006, this TSB does not apply, perform normal diagnostics.
  2. Isolate the source of the noise to the cam cover on either Bank 1 or Bank 2. If the noise is not isolated to either cam cover, this TSB does not apply. Follow normal Workshop Manual (WSM) procedures for additional diagnostics.
  3. Remove the appropriate cam cover.
  4. Check for stuck/collapsed lash adjuster(s) by placing the cam lobe on the base circle and inspecting for loose cam followers as a result of the lash adjuster plunger being bottomed out.

    NOTE:A COLLAPSED LASH ADJUSTER WILL RESULT IN EXCESSIVE CLEARANCE BETWEEN THE LASH ADJUSTER AND THE CAM FOLLOWER.

    NOTE:WHEN CHECKING “3V” LASH ADJUSTERS – A “SPONGY” LASH ADJUSTER IS NORMAL WHEN OIL PRESSURE IS “NOT” APPLIED.

  5. Replace only the affected lash adjuster(s) on the affected bank(s) following the procedures outlined in the appropriate WSM, Section 303.
