Here is the backstory.
Wife had her 2004 Jeep Wrangler running and driving fine and the transmission went out about 2 years ago, it was a 42rle. The Jeep sat at her parents ranch outside with no transmission in it. She recently bought a used transmission (42rle).
I installed it myself and got ready to bolt it up to the flywheel when I noticed the engine wouldn't turn by hand. I tried turning the engine over with the key, and it did one rotation and wouldn't budge after that, neither by the starter nor by hand.
Furthermore, I squirted liquid wrench down the spark plug holes and tried turning it by hand again, and it wouldn't budge. I now have the heads off, starter off, oil pan off, and still cannot get the engine unseized. I have tried taking a butane torch to heat up the cylinder walls/pistons, and banging the pistons with a hammer and wood block, then a hammer and steel pipe, no luck. The front damper bolt won't turn the engine, that's what I've been trying to turn it by hand with a breaker bar and a cheater bar that is about 3.5-4 feet long, it has been turning the bolt eating at the washer and not turning the engine.
Any advice as to get this thing running again? I feel like I'm running out of options, and I'm going to have to go buy her a new engine...
