PS, the Chevy long block was "remanufactured" out of Mexico...also I noted the the front cam bearing was missaligned, oil had a hard time getting to the front main...slight gawl on that bearing but it didn't mess up the crank bearing surface....cam bearing is still good , but will need a drill...
Thinking bout it,that 1 cylinder...but the heads /bolts came out off pretty easy..it might be a waste of timeand money...I don't think anyone, who is honest will say they ever saw a hairline crack in a cylinder...maybe if they were actual machinist, a rare occurrence might turn up, but not most...
Hairline crack in the cylinder? Or something else? Elaborate. Anyone ever see a hairline crack in just one cylinder that can't be seen when it's magniflux , with the naked eye?
You should have known most machine shops won't bore/hone just one cyl. They are in the business to make/ take your money. They want to door the whole block over again. All 8
