Steve,
Its highly likely that the problem is that the rings
have rusted and bonded themselves to the cylinder
bores. The valve train being stuck and preventing the
engine is unlikely, unless of course something is
broken, in which case that could actually lock an
engine. I would follow the good advice that has
already been posted on the subject. I would also add
that it might be a good idea to pull the valve cover
and make sure that the lobes and lifters, or at least
the high pressure contact areas are lubed well before
you try turning the engine over.
But, as I said, I'd say that if the engine is stuck
just from sitting, then its the rings and bores that
are causing the problem. If the engine is seized
because it was run without oil/oil pressure, then even
if you do manage to get it to move (very unlikely) it
probably won't be worth anything when you do.
Regards,
Ben Pender
