What options would I have to repair a scratched cylinder wall? It is a fairly deep scratch, easily catch a fingernail on it. Owner says a piece of the ceramic around the electrode of the #3 plug broke off and caused it. He changed out the plug and has been driving it for the last year like that. Only problem is burning alot of oil, especially at start up and notices blue smoke between gears but not so much at idle. It is a G63B (2.0) out of a 83 Power Ram50. I dont believe honing will get it all. Can it be bored out and oversized pistons installed(availability of parts?) Or can it be resleeved? Or is there another option?
