Many engine block cracks are caused by contaminants making their way into the metal of the part during the manufacturing process. In these cases, a poorly cast block can start to leak, whether coolant or oil, from the crack itself.

Can antifreeze leak from the engine block?
A cracked engine block can cause a range of problems. Ultimately, since the circulation system that cools the engine is comparatively fragile, a cracked engine block will lead to coolant leaking out of the area it is needed and leaving the engine to overheat.
What happens if coolant gets into the engine?
Coolant that leaks into the combustion chamber will cause the white smoke and milky oil as noted above. It can also produce white deposits that will foul the spark plugs and cause additional engine power failures.
