That is a controlled test. In my real world use Kroil is the best with PB blaster close behind. Liquid wrench I stopped using because these were so much better.

I have a 580K and I have the same problem. I just took the pump off to expose the harmonic balancer bolt. Guess what! No Harmonic balancer or bolt. Just a 1/2” pin to locate the adapter for the hyd pump. Don’t know what to do now. Yours may be different. I hope so.
Amen to DMiller's comment.
When a piston is stuck that severely, it isn't worth breaking a ring-gear tooth or twisting off a crankshaft bolt when a complete overhaul is inevitable.
The sleeve will prolly have to be cut off of the piston to prevent any damage to the connecting rod. IMHO.
