Bear in mind that the bolts are torque to yield type with tightening sequence being 4nm then 65 degrees. Will be best to fit new bolts. There is a a good chance old bolts have been used and due to being overstretched have loosened off leaving the clamp loose allowing engine vibration to cause the fracture.
