    main bearing damage

    could a unbalanced crank with carrillo rods cause main bearing damage????


    what are the biggest reasons that these engines could have main bearing damage???

    Most likey is..... loss of Oil Pressure. But normally you will see Rod brg failure before you see Main brg failure.. Has the Main brg bore sizes been checked? Has the crank been checked to see if it is straight?
