From what I know my motors inside is stock with 125k miles on it. The question is how long before a crank that is polished will start to have oil pressure issues. I cant understand why no one makes bearings that allow you to grind of .010 to fix any problems , If you look at the surface were the bearing spun under a microscope you will see a very bad surface, It is actually peaks any valleys ,to get it polished removes all this .In the process it reduces the pin diameter.This will at some point have an effect on oil pressure. What is the tolerance on main and rod pin diameters?
