    It could be the harmonic balancer moving around causing the knocking. If its got any movement in it at all, its stuffed and will need replacing. You need to remove the belt to check the balancer for movement. It could also be the reason the CAS wiring ended up hitting the belt.

    If its not anything external like the balancer, then the engine is probably stuffed if its making that much of a noise internally.

    sounds bad, but also could be belt tensioner? ive herd they can cause a bad knock when ####ed and can throw belt off etc, worth a shot, take the belt off and start car, if its still there its internal if not check all drive pulleys etc
