Fifty-five years ago, had one engine sitting outside for 10 years that locked up.

1. Took it inside, removed head, removed oil pan, & removed crankshaft; "then" found (3) pistons could move & (1) could not.

2. Only concentrated on soaking & moving this (1) non-moving piston.

3. Back then, soaked with Liquid-Wrench for about a week & lightly tapped top of piston with a pine 2x4 every day after soaking for (2) days.

4. It finally broke loose, so I kept the same rings, same pistons, then honed cylinders slightly & re-assembled -- great engine.
