 Topic: Cracked B block
Posted: 19 Dec 2019 at 8:38pm |
|
Friend of mine has a B with a crack in the block between the cylinders. Is this repairable? Or should he be looking for a new block?
Cheers
Creek

Small cracks are not a problem.. If it is bigger than 1/16 inch, Dick L had a procedure several years ago to remove the freeze plugs on the side of the block, cross drill holes between the liners, and pull the block back together.... maybe he will post a link.

Nevada Cylinder Head at Nevada Iowa welds and straightens the bores of broken blocks.

Hair line crakes between cylinders are normal in wet sleeved engines when they have been over heated. They do not cause a problem. The head gasket seals them just the same as the crack that runs 360ยบ around the out side of all wet sleeves. If you have a crack wider than a hair crack it can be pulled back with a tie bolt. Tie bolts were used early in manufacturing some wet sleeved engines to prevent cracking. It was used to repair these engines by dealerships in the 40's and most likely earlier. I picked it up from an old tractor mechanic and took pictures to pass it on to DIY ers using simple tools most have or can obtain inexpensive easily. https://public.fotki.com/DickL/tie_bolt_story/

Thanks for your input, I will pass it on to him. I thought I remembered that the crack between the cylinders was fairly common in the D17 diesels, but didn't know if it applied to the smaller gas stuff too.
Lon I will let him know you have a block in case he wants to go that route.
cheers,
Creek
