Causes for a seized engine?

[chuckstp]

I am pretty sure 2 & 3 are close, so yes. I did find that when it stops at either extreme, I am able to depress both valve springs for 2 & 3 and can see that the valves drop when I do that. Still, the next step appears to be the same no matter what. The head and or the timing cover needs to come off. First though, I need to get it out of its current location so I can take it somewhere to work on it. It's clear the engine isn't going to help out in this matter.
