The Stovebolt Site Forums The Shop Area Engine Shop 1962 gmc 920

New to the site ,just purchased a 1962 gmc c920, 261 CID ,4 speed, the engine had a major piston failure,rod through cylinder,not through block. Any luck salvaging from this type of failure,a local machine shop says it can be sleeved,any thoughts?

Not an engine machinist and invoking the memory escape clause because it was a long time ago when I heard about this.

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.

I worked in a machine shop when I was a teenager and I say many motors that had rod failures such as that sleeved and repaired. They were known in the business and the odd antique motor was repaired too, complete with hole through the side of the block.

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.
