I repaired one of the holes for a head bolt on my 97 Honda Accord using a time sert insert. When I put the head back on I was only able to tighten it to 63 ft-lbs. I could tell it wasn't going to tighten an more at that point and I stopped. Anyone know what is the chance it will hold like that, without torquing it down all the way to 72? Since it's aluminium, I've read that they can't be repaired reliably. Should I just try to find another engine block? There might have been some cutting oil left in the new hole since I didn't clean it out all the way. Which may be why I'm not able to torque it down all the way.

  • Wouldn't tighten anymore because you were afraid it would break or strip? – JPhi1618 May 20 '16 at 16:25
  • I was afraid it would strip, the torque stopped increasing at that point. I'm using a torque wrench with a dial guage. – willpb May 20 '16 at 16:30
  • Why not take it apart, make sure the bolt hole is clear and try again? – Ben May 20 '16 at 20:23
  • If you did not clean the hole, more than likely it is hydraulic locked. In other words it cannot compress the fluid you left in the hole. – Moab May 20 '16 at 21:44
  • It wouldn't have that much oil in the hole to be hydraulic locked. – willpb May 21 '16 at 15:25
