adrianphu123 73 Posted September 17, 2022 Hey guys Replacing the head and gasket on the crossflow, pulled the threads out of the block on the second pass. Anyone had this happen and how did you guys resolve it? Hole is the rear dowel pin if that makes a difference. Head has been serviced and torque wrench was used. All threads chased with a thread cleaner and new head bolts. Thanks in advance, adrian Share this post Link to post Share on other sites
bear351c 10,270 Posted September 18, 2022 Products like Helicoil, or Recoil will fix it. You need to rethread (tap) the hole, and install a "coil" with the head bolt thread on the inner surface. Looks like a small spring. 1 gregaust reacted to this Share this post Link to post Share on other sites

cisco 111 Posted September 18, 2022 If you pulled the thread using a torque wrench set correctly it suggests to me that you have "tired iron". If it is just the engine in your daily banger, using helicoils will get you back on the road. If the engine is a project for a performance car you might want to rethink about using that block.
