Thinking of rebuilding my Lycoming 320D3G. I have rebuilt several auto engines including a Mazda rotary. And after checking into prices for engines.... ECI Lycoming etc. rebuilding my own is starting to look pretty good. I'm looking for comments,advice and suggestions. I have checked in to having Divco do my crankcase and Aircraft Specialties do all my steel parts. I would put all new cylinder assemblies on. My carb.and Mag have less than 100 hours on them and the rest of the accessories only have the 248 hours on them. Has any body out there rebuilt their own Lycoming engine? If so I would love to hear how it went. Thanks, Greg
