  • Engine: Water out of last head bolt hole.

    I rebuilt a V 8.
    Started it to check it out.
    Engine ran fine.
    Then I wanted to change the "Accelerator cross shaft".
    Took out the last head bolt on the driver side to which the accelerator cross shaft mounts.
    Water came out of the head bolt hole.
    Is this normal or do I have to pull the head?

    Normal, some of the bolts go into the water jacket and therefore will leak if you remove them with coolant present.

      Congratulations on the "Engine ran fine”!! I hope in a couple of months I can post the same.

        Drain the cooling system. Using a suction gun, insert the tube into the bolt hole as far as it will go, draw out the coolant. Repete as necessary. When you can't remove anymore coolant with the suction gun, use compressed air with an extended tip to remove the last of the remaining coolant. Use a small amount of motor oil on the threads of the bolt, reinstall and torque to 55-65 ft/lbs. Reinstall coolant. Hope this helps.

          Mmmm, beg to differ slightly from Dans comment.
          While on one hand, what's said id fine...IF...that's the way the head bolts were originally installed.

          If they were installed the same.
          If engine oil was used, do the same.
          If moly was used, do the same.

          Otherwise, the actual clamping force will be different, despite the same torque wrench reading.

              Thanks everyone.
              I just needed reassurance.
              I rebuilt dozens of these but never took out one of these bolts in the rear after
              it was full of liquid.
              Back to it.
