I don't know about the electrolysis
I don't think so.
I Have never tried this but I want to someday.
What about if you disconected the conectingrods that you can so that you can work on just a couple stuck pistions at a time.
Try and shrink the pistion with liquid nitrogen or a CO2 extinguisher or dry ice.
I know that sounds crazy but I always wanted to try it. It would be a bit expensive.
I use to heat large nut and bolts with a torch and then dump cold water on to them.
I think it worked.
I think that the object with less mass (nut) gave up its heat quicker then the object with the greater mass (bolt) and contracted to a smaller size thus pulling apart the bond enough so when I pulled on the wrench it turned.
I don,t know how much heat the pistions could take if that method was tried with the engine.
After being rapidly cooled, I dont think I would trust the pistions.
I don't think simply cooling the pistion ......
wait: It dont take very much cold temp to make metal weak also. If it was cold enough then it could make the ring lands brittle enough that they could crack.
I don't know!
But I did this much typing so I am going to send it anyway. LOL
