That previous 318i post is unbelievable. What on earth happened to the education system in the years since I graduated from high school?

Anyway, a great thread today confirmed, in addition to what ElwoodBlues posted, there's yet another type of mechanical tensioner that looks different than the ones pictured prior.

Since the identification of the type of tensioners is visual, I'll repost the picture here from a 2003 BMW 525i.

Notice the lack of the raised molded nut. Instead there's a sunken Torx #60 indentation. Who knew!
