RE: Hemi Tick
For what it's worth, mine has 6,900 miles. I didn't have or at least didn't notice any ticking until it seemed just after 5,000 miles. Now, I can definitely hear it. From looking into this, though, it seems a lot of people have experienced the no tick to tick syndrome and most seem to chalk it up to the lifters following break-in. Most people also say that as long as it doesn't get noticeably louder than should be fine. Doesn't hurt to take it to another dealer, though, for your own sanity.
