Even though installing rod bolts seem like a fairly straight forward process, it is not a DIY process that many people can do successfully because it takes specialty equipment to do it correctly. They have to be pressed into the rods so that they do fully seat into the rods. You can actually stretch the threads by using the nuts to tighten and pull them through and ruining the bolts. If you think they were not fully seated in the rods from being installed in this manner, they were also not correctly reconditioned either, and now that they are fully seated you will need to have them reconditioned again or you will have more problems. I can't tell you how many thousands of connecting rods I have reconditioned, but I have seen every problem that can occur from them being installed incorrectly. Stop before you go any further and have them re-examined by your machine shop now that you have found this error.
