I’ve found PB Blaster to work best. Frees up rusted bolts & nuts better than anything else. So cleans cylinders & rings best too. Got my wife’s Corolla with one 60psi cylinder back up to 195psi. Similar car with same issue picture posted above. I was able to skip the teardown.

I think you can remove pistons with engine in frame by removing head and dropping oil-pan. But it’s a lot quicker and easier to remove engine 1st.
