Thanks v-10 doubletow for the education on the manufactoring process on the rods. Yes, the rod probably bent upon starting the morning the knock was first detected. I have ruled out water, so fuel or some other malfunction is to blame. As to the repair, are the rods a nonserviceable part, if I choose to do a rebuild? Maybe I will just get a longblock remaned from Jasper or another rebuilder. Any input on remaned engine experience from forum members will be greatly appreciated.
