1. Cracks between the bores at the top deck. Not common but does happen.
2. Check the 3 main caps are original, best done by measuring diameter but a fingernail on the joints will usually show if they don't belong.
Caps were line bored with the block originally.
A block with no caps = a doorstop (unless you want to pay for a set of new steel ones and a line bore job).
