With the engine cool and the plug out, it was still a little tight at TDC and it clicked, but I was able to turn it over by hand. With the plug in, it still had compression but no piston friction at TDC.

Is my motor done, or do I need to replace the piston sleeve rod?

You should be fine!!! I have run my engines up to 280 or more at times and they have been fine.... Just not the kind of thing you want to make a habit out of. Just keep running it, when it will no longer hold an idle and it seems to die a lot is when you will need a new P/S/R
