Soaked the pistons to get rid of all the carbon. It is a lot of work but I rehabitated 2 engines.

Breaking Piston Rings pushing them out generally happens if you don't ream off the ridge at the Top of the Cylinder. The Ridge is formed by the unworn part of the Liner and Carbon Buildup.
I think you can find instructions on how to use a Ridge Reamer in a General Automotive Book you find in the Library or of course there should be pics on the Internet somewhere.
Back in the 1960s-1970s they used to rent Tools like a Ridge Reamer. I have owned one so long I don't know if they still do that or not.
Somplace that rents Torque Wrenches might also rent other Engine overhaul Tools.
