Seems to be quite a few, Norm.Haven't heard that.
There is the "Hemi tick" in VVT models, there is the 3.8 V6 tick because of the poor qualify of the exhaust manifolds, but this is the first I have heard of a Pentastar tick.
Could be an isolated case?
From "all" of these reports, is it affecting performance, or causing other issues, or is just a noise?
I confess that I rarely visit those sites, too many [this word has been banned due to its use as a pointless flame tool]ys, and uncivil posters there for my taste.
Hmm, considering how complex that head is, that is ominous.Norm,
It sounds like some owners had their engines torn down, heads replaced, etc.
Not sure about performance issues.....but something is brewing here. (JeepForum has two threads on this...one rather long)
I'm surprised this hasn't popped up here at Allpar.
