Yep thats the sign!
The next one is a hole in the piston!

Again go to the swap meets and find the parts you need

If your jug is bad just have it replated, I send mine to US Chrome in Wi.

I have sent them over sized pistons and they can bore it and replate it over sized!
I have had a 580 bored out to 625? or so
Comes back even better than new!

Do NOT just replace rings!
Always replace piston as it comes with rings!
The Piston is what is worn!
