I too have the tick from time to time and have been debating on going to the dealer for diagnosis. But to be honest I am paranoid about having some one rip into my engine until I can confirm what needs to be done.
It is distinctly different than the injectors which has a less metallic sound and a faster rythm. Mine started after the first few thousand miles and sounds similar to a stuck lifter on the passenger side but hard to tell. I have been running 5W20 fully synthetic since new. The sound comes and goes and is not consistent enough to be piston slap. I noticed it happens more often when it is cold than when it is fully warm. Often times if you rev the engine up a couple times it will go away, only to return later. Very odd, but interesting to hear many have ran into the same issue.
