RESIZE CRACKED RODS? YES YOU CAN
There is a way to recondition the so-called “cracked” rods, or powdered metal connecting rods. I use a media made of coal slag that can be found at most home improvement stores. You have to blast the 4 mating surfaces on the rod and cap. The key is to use low pressure and go slow. Blast for no longer then 2 seconds or you’ll remove too much material. Try a 1-second blast to start. I made a rod .015” to small on my first attempt. Make sure you thoroughly clean the threads in the rod before installing the bolts and resizing the rod.
