The following information is what I've learned from reading way too many posts on the subject.

You're interested in the adaptation value. Ideally, it's zero, but as your chains wear, they will get noisy and once you get around -8 to -9 you can expect a failure. At that point you should have a significant amount of rattle, especially on cold startups.Address 01: Engine (7P0 907 401 K)
