I'm doing my own overhaul on an IO-320-C1A. It's my first airplane engine overhaul. Not my first engine overhaul. I'm trying to figure out what hardware has to be replaced. I know that I have to replace the rod bolts and the crankshaft gear bolt. What else? I'm getting a couple of different answers, so I thought that I'd ask VAF.
