Stuck piston ring

Marvel mystery oil.
Straight in the crank case, or in the plug hole?
I’ve used ATF too, through the spark plug hole. Multiple treatments are needed sometimes.
Both. You can put it in the gas too.

If you're really trying you save the oil, you could drain it into a clean container before adding the ATF. Just leave the drain plug out and let the ATF drain out into a separate pan after letting is soak and it leaks past the rings. Rotate the engine by hand and flush it with a quart or 2 of oil before replacing the plug and filling back up.
I had thought of that, also
I don’t think Grandma wants me messing with it
I have used Marvel Mystery Oil a couple of times. Let soak for a few days.
Giggle spray. Maybe a 50 shot. Just enough to get the combustion pressure behind the stuck ring and gently “push” it back to the bore.
I've done PB blaster in the plug hole and rock the crank with a breaker bar...I made the mistake of starting one that sat 16 years with the starter once, bent two pushrods....now I use a bar.
You can put Marvel Mystery Oil in the crankcase and the fuel. Used to do it all the time on my 76. Never hurt anything.
Are you getting the engine warm enough to get everything to expand just a bit? Takes awhile sometimes, especially with our cast iron blocks.

Soak all the cylinders for a week or so then with the plugs still out and the ignition wire removed, crank over. If there is no compression shouldn't have any bent pushrods. My Jimmy sat for a good 10 or 12 years and its how I got it running again.
I had a couple different theories before I posted.
GM crate ZZ4. Fresh synthetic oil
Only ticks and blows by, only when hot
This engine had the beans run out of it before we stuck it in moms SS
One theory was the ring stuck in the piston. Ticking with blowby
The other thing I hasn’t already mentioned but wondered about is the oil. So Wade and I were on the same page. Ticking and blowby because the oil is too thin
