Some cracks at the earliest stages are barely visible even w/penetrant or magnaflux, but the different sound w/a cracked crank crack is legit. The sound is very different w/a significantly cracked crank and to someone who deals w/them on a regular basis its a no brainer. Not so much to someone like us who don't handle cranks a hundred times a day unless the crack is bad or you have a good one to compare it to.
