Any luck salvaging from this type of failure,a local machine shop says it can be sleeved,any thoughts?

Some engines, I believe over the road diesel truck engines had the actual cylinder wall made from a sleeve installed into the block when the engine was made at the factory for the first time. Meaning the cylinder wall was not cast in and the sleeve was a wet sleeve. Meaning that the outside of the sleeve was part of the water jacket and in direct contact with the coolant.
And, I do not think a machine shop would offer a repair that would not stand up.
Also some engines that have had cylinder walls too badly damaged to repair by boring oversized had them bored then re-sleeved to standard size.

They were known in the business and the odd antique motor was repaired too, complete with hole through the side of the block. | | | | | Joined: Dec 2001 Posts: 14,522 Moderator: Welcome Centre, Southern Bolters, Legion Hall | | Moderator: Welcome Centre, Southern Bolters, Legion Hall Joined: Dec 2001 Posts: 14,522 | GMCKid, welcome to the Stovebolt where knowledge is the best resource and there is plenty of guys and gals where willing to share it with you.
AS you get more into your project you will find all the answers you need in the garage forums. Good luck and post us up a picture when you can.
I see your in the Vancover area and the bolters there call themselves the B.C. Bolters. A good bunch. You just missed the picnic out at 3B's place. Keep watch for them. They'll be around.
