Daughter killed car?

Thanks i can use some good luck. I removed the plugs and water ran out of one cylinder but the engine still will not turn over. The oil looks fine will try the liquid wrench before i conclude the engine is toast. Ford wants $2,400 for a rebuilt motor did not even ask about the labor- might of stopped my heart- my goodness been a long time since i had to replace a motor inflation sure rekindles my feeling of money being more paper and less currency.
