If the bottom end spins and the top doesn't, then you are missing some teeth
on the belt somewhere (in the very least). What caused this could have just
been age of the belt, but something could have locked up too. The camshaft
is one of the last things to get oiled, so if you run low on oil, you can
seize the shaft in the journals in the head. Also, a locked up distributor
can keep the cam from turning.
