2002 Saturn L200 TIMING CHAIN

HOW DO YOU KNOW IF THE ENEGINE IS RUINED IF YOUR TIMING CHAIN WENT OUT? LEAVING HOME TO GO TO WORK TURNED ON THE STREET, GOING ABOUT 10MPH WHEN I LOST POWER, HAD SOMEONE LOOK AT MY CAR AND THEY TOLD ME MY TIMING CHAIN WENT OUT, BUT THEN READING ONLINE ABOUT TIMING CHAINS SAW THAT IT COULD DAMAGE THE ENEGINE.
