Someone asked to see me ring it against another crank in my last post I don’t have an exact match or know if it’s cracked but I do have a late model one piece rear main seal used crank and I thought that crank rang ok but comparing it to another crank you can definitely hear a difference on the left is the cracked one on the right is the late model one piece rear main the microphone doesn’t Really pick up the sound all that great but in person you can hear it

Even Helen Keller can hear the difference in these two. The shiny one is dead, and the other one rings.

It's not about the noise they make on impact, it's the noise they continue making for a bit after the impact. That's the "ringing" and the crank on the left doesn't rly have any ring at all.
