Now I’m faced with my next hurdle. I moved on to the valve stem seal project using the AGA tool kit. I started with the #1 cylinder. I got it to what I rotated the engine to what I thought was TDC, but when I hooked up the leak down tester and pressurized it, I could hear leakage from the valves somewhere. So I let the pressure off, but now when I try to rotate the engine anymore, it gets stuck at one point. And when I try rotating it back the other way, it gets stuck about 180 degrees later.

Searching around, it looks like this might indicate bent valves! However, the engine was running perfectly before I started this project, so it seems unlikely it could be bent valves.

What else could it be?
