    I DONT FEEL PACK2 CAN SOLVE THE KNOCKING ......
    DOES ANY ONE KNOWS ?

    I got to replaced twice，first time by warranty at 270k miles , then failed on 440k miles....
    changed to PACK2 , but after less than 10k miles.
    knocking back again and fuel efficiency very bad...
    some one saying they just enlarged the holes on injector?

    Keep taking it back. Its their issue until warranty is done. Those engines are only good for so long. Than you do not inframe it. You order a complete reman.
