Possibly, depends on where it broke and how. If chunks flew off and hammered up
the spark plug, and or bend a valves, there would be no firing of the fuel
charge, hence no "great belching of sump contents." Keep in mind I'm not saying
it's a broken piston, just a possibility. Loud noises and loss of power are not
"good" omens.
Take out all your spark plugs as a first check.
