Re: Piston/Ring issue???
If you have access to a lathe with a 4 jaw chuck you can chuck it up and zero one side of the groove and then indicate the other......
A wavy groove would show up pretty fast............
Or...
You could use a surface plate and a height indicator on both sides of the groove......
And a plus would be that YOU knew for sure....
Just a thought from an old machinist guy,
