[QUOTE="airblazer, post: 184655, member: 6648"] [ATTACH]64484[/ATTACH] [ATTACH]64485[/ATTACH] There’s a big line around a third of cylinder wall that I can feel with my fingernail. The other rust spots/pits are less damning, but some don’t pass the fingernail test. So I assume this cylinder is a candidate for bore-up or pencil holder...:( The rockers are also done as they have obvious wear patterns on them. The cam seems usable to me, no wear/corrosion on it like the rockers and cylinder. I don’t know what to look for as far as valve wear is concerned...any tips? I’m in unexpected terrain now.
