SH Crack between #12 cyl wall

Va Gasman · May 9, 2012

I have found that the #2 Sleeve was cracked .I have pulled it and there is a longitudal crack 3" long on the web side of #1 & #2 cylinders. Is this repairable with block sealer or repair epoxys? I have been told by a mechanic they repaired and old Allis with K&W.
It looks like that if you are to reinstall a new sleeve that it would be do-able.
Your inputs are appreciated. This Sh stage II is beyond going south on me , it's beginning to eat my lunch.

I have used JB weld quick set and it worked okay.

Anything is possible, but if you want it done it right, so you don't have to do it again, either have the block repaired professionally, or find another block.

I have a block out of an M with a similar crack. That block is now serving duty as a yard ornament/flower planter.

I have an extra SH block with "Z" casting codes. Looks good but has not been professionally checked. Email if interested.

You need to answer a few questions first, but to yourself only. These are:
1. Is the crack structural. . . was it caused by wear and tear, overheating, or was it caused by freezing? If it was wear and tear or overheating get another block.
2. If improperly repaired will it cause problems in the future? Any adhesive or chemical weld will tend to break down over time. If the crack is not between oil and coolant or the outside it may not be that critical. If it is then you need to make sure it is sealed by welding or brazing. If it can't be welded or brazed get another block.
3. If in doubt, get another block.

Did the crack in the block cause the sleeve to crack? If so, find another block.
