Does this engine need to be replaced?

Car had an oil leak for past 2 months, Checked and refilled oil as needed, Could see smoke from under hood when car was stopped at a stop light. Son borrowed car.
Checked oil and reported it appeared to be too full When driving home he heard a buzzing whining sound (not very loud). Started to lose power and stopped. Could not turn the engine over after it stopped and still won't. Upon inspection after tow, engine appears to have exploded from the side. Please see picture.
