Sounds fine to me, but I know that feeling, it will probably keep nagging at you. Personally though Id try to forget it if its running well. If really worried check oil for any metal, send in for oil analysis, and maybe pull valve covers just looking for anything obvious. I wouldnt go any farther than that without more proof of an issue.
