The answer is..

Well, I have watched this thread morph with a fascinated interest. What was originally my question about when to change the timing chain morphed into a fascinating discussion about which direction the link should face. Love the detail.

Well anyway, I finally got the answer I was looking for from the Technical Letters section of the most recent Star magazine.

The editor says (for duplex only):

100k miles: change not necessary, but will noticeably improve performance.

150k miles: change recommended soon.

200k miles: change now, performance will improve greatly.

If you have a single chain, then convert it to duplex as soon as possible.

Thanks all for your comments. :p
