Seized motor
After taking the header off I can see rusty water coming out of the exhaust ports. I'm thinking this should be a clear indication of what the problem is (why the motor is seized) and I'm asking the engine experts here what that problem would be. Seals?
thanks,
Stan

the initial problem could have been a bad coolant seal or seals. another issue could have been a corroded rotor housing around the coolant seal. both issues will allow coolant into the engine and over time, rust will develop. another issue could be that someone let the car or enginesit outside and water could have gotten into the carb and into the engine. get the water out and fill it with marvel mystery oil and let it sit and keep trying to rotate it. that or tear it down and salvage what you can..

If it's rusted solid, may I suggest AeroKroil? It's an industrial strength penetrating oil that will eat through the rust pretty quickly. If it is rusted solid, the irons may need to be replaced, so I'd suggest trying AeroKroil, and if it all frees up in there, MMO it and let that soak for a few days, and then drive it. You won't cause anymore damage than has already happened with the rust.

The good news is you can finally have an excuse to do the TII swap!

Thanks guys.
I had read about the MMO trick and have hope yet that that will work. Worse case....it won't.
...then I start entertaining engine swaps...

Water got in through the carb. Time for engine tear down and rebuild. Side plates are probably damaged. Side seals are stuck in rotors. No amount of magic fluid will free them up.
Or maybe the PO used straight water in the cooling system. Corroded/pitted the aluminum which allowed water to leak in through the threaded part of the spark plug holes.
