+1 on the tensioners. I had a brief rattle on startup. Changed out all three tensioners. Problem solved. One of the tensioners was very weak.
FYI, I can't remember the specifics, but there was an upgrade to the tensioners at some point, so make sure you do your research when you shop for the parts.
