Thank you for the reply, They have been having some problems with the hydraulic lash adjusters on the 2006 5.4ltr engines according to the engine build dates and from your description thats what it sounds like, here is a copy of the service bulletin for the concern, check the build date on the timing cover for your engine to see if it in the time range, its only covered under the limited vehicle warrenty coverage and an extended service contract if you have one, the cost will be hard to say depending on how many lash adjusters need to be replaced and if they are on both sides, if on both sides its about 8.5 hours at the labor rate for your area plus parts.
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.
Verify engine build date, isolate, and replace any stuck/collapsed lash adjuster by following the Service Procedure.
