Frozen 226 any ideas?

Just pulling our father's 54 Manhattan out of storage after 30 years and motor is locked up. Been spraying the cylinders down with Seafoam Creep and PB for 4 days, no luck turning with breaker bar from crank bolt.

Let the solvent soak for several days. If after a week or so things are still stuck, you may have to remove the cylinder head to see if there is any serious corrosion. With the head off, you can try using a soft block of wood placed on the piston and tapped with a hammer. The shock transmitted thru the wood sometimes breaks things loose. I had luck with a stuck Allstate engine using the block of wood process.

I had good luck soaking with Marvel Mystery Oil once. Cranked it with the starter after the previous owner totally destroyed the clutch trying to break it loose while towing it.

I recently heard a 50/50 mix of acetone & automatic trans fluid works good. Sometime I'll be tearing my engine down after sitting 30+ years and even though I squirted some MMO in last year, I plan on juicing up the cylinders with that mix soon.

Try putting the acetone/ atf mix down the valve guides. You'll have to pull the head. Mine had the two center valves stuck. Valves could be stuck to their seats too. I had  a Rambler 232 of mine freed up by filling the cylinders with kerosene and setting it on fire! That car ran like a champ and used no oil. True story.
