mine seems loose too. Good question

I usually chuck them when they get past 1/2" play. I've never heard of one letting go, but they do get noisy.

i think it's 3/8ths

If the slack is more then 12mm replace it. I replace most of the oil pump chains. I barely find one up to specs.

how are they from mazda?
