This is probably going to be the first of many questions that I'm going to have. I've got a Lyc IO-320-C1A that I'm planning to overhaul. I have no logs and no history. The price was right however. $0 I'd like to do as much of the work as I can, mostly for my own education and if I save some money then that's okay too. I have it torn apart and I'm ready to send it off to DivCo and Rick Romans to have all the parts inspected. I pretty well know to send the crankcase halves and the accessory case to DivCo. (I plan to replace the sump with a vertical induction variety since this one won't fit in the Pitts.) Anything else? What steel parts do I send to have inspected? Obviously the crank, cam, rods, gears and lifters. What else? Push rods? Gear shafts? What about the Oil pump parts. One gear is aluminum and the other is steel. Do I just replace those? I have a pretty large selection of mics and indicators (and I know how to use them) so I can measure most of this stuff if all that is needed are dimensional inspections. What's the best way to pack all this stuff?
