Hey, i have a piston with some stuck rings and I'm wondering what i can do to get them unstuck. i've tried some mechanical methods, picks, tapping with a hammer, rolling against a cast iron table while tapping with a hammer. nothing! so now I'm soaking it in ATF, i let it sit overnight in the cold (freezing up here now) and then i microwaved it for 3 minutes till it was very hot and its still soaking. if this doesn't work, what else should i try?
when i was searching i found some WEIRD home remedies for rust, such as a dilution of water and molasses to remove rust. i may try it on the crankshaft of this engine since theres some hard to reach areas of it.
if you're wondering, the engine is a 1977/78 Minarelli V1. the stuck rings and rusty crank are the parts engine which I've split and setup for testing
I'd like to try to save this piston since its in good shape. I've been working the cylinders lip down to raise compression, and with this mock up and a few more bolts and nuts and a aluminum head gasket i can check cold compression off the engine to see how much I've raised the compression.
