Hey Mark, yup. The bronze bushing thingy on the conrod is nasty when it disintegrates. It splatters all around in the engine and will sand blast the button head and piston top. How bad is the piston and liner? Sometimes they could still be used.
Take off the whole engine and give it a thorough wash with a nitro cleaner. If possible, take off the bearings too. Use a heating plate. Check and see if they are gritty as a result from that incident.
If they are, then you need to replace them as well. I don't know how much you can get the individual spare parts and how much they can add up too. Perhaps since NovaMega engines are difficult to find, you could try the Novarossi route or the JP FX engine. You can try HK online shops. They may be cheaper.
Sad to have to read through this early in the morning...
