There is another thread indicating it is a problem through late 2008 or early 2009 motor production. I am hoping my June 2009 car build has the later parts but I have not checked the head casting to know for sure. My motor sounds fine, however.

I still haven't figured out how much of an issue this is. It seems to me that the clearance will disappear when the oil pressure rises. If so, then it seems more of an annoyance than a big issue. In other words, it is more important that your valve clearance be limited when you are under power than it is whatever it is at idle.
