So I spun a rod bearing recently and two of the pistons are somewhat difficult to turn on their wrist pins. They do turn and slide back and forth in the piston, but it requires a fair amount of effort, a good amount more than the other 2. I soaked them in brake cleaner and worked them back and forth for a while, but they don't seem to be getting any easier to turn. I am concerned that bearing material managed to find its way into the wrist pin location. Or am I just being paranoid? Is it okay for the pins to be kind of stiff?? Is there anything I can do to loosen them up? I really want to get my motor back together, but I don't want it to just blow again as soon as I do.
