Technical Welding a cracked block

Looks good...

 

When my brother and I were in grade school a friend of the family gave us a '60 Chevy hard top with a 283 and four-on-the-floor to play with. We'd been told the engine had frozen and busted finding a "T" shaped crack on both sides of the lifter galley when we removed the intake, a welder friend had us "V" the crack out with a cold chisel then when he was satisfied with our work he got busy with a pipeline special welder and some 6011 rod, he'd weld an inch or so and I'd peen the dog-slobber out of the weld with the pointed end of a slag hammer. After the welding was done we reinstalled the intake, changed the oil, filled the radiator with water and a can or two of stop-leak both us brothers using that poor innocent car to learn how to drive. Unfortunately, grandpa caught us engaging in "spirited driving" selling the car before we got hurt. Best of luck with your project.

 

Peening the weld is the answer. It compresses the metal. capish? lippy

 

Your repair is as good as if God sent it to that way

 

I personally like your repair. I hope it works well. As others have said, keep us in the loop; you may have discovered a new technique.

 

Or stumbled upon an old one !

 

When it is brazed the the two metals blend into an alloy at the interface to form a contiguous part. Screws are still seperate pieces of metal.

 

I was a Stationary Engineer by trade for 35 years . We will be long gone before any dissimilar metal issues arise . I saw and worked on 1000s of brass fittings screwed into steel and cast iron . Seems to be a different outcome when the fittings are buried

 

Looks like a good repair.

The crack probably was a result from freezing. It is in a none stress area, except when it freezes . Anything filling the crack would probably work. Your fix looks as traditional as it gets. We have a tendency to overthink the problem.

 

Peening expands the weld.

 

Looks like an excellent repair! I’m betting you will have no problem with it.
There was a machinist , here in Muskogee, that used to repair stuff with that lock and stitch method with great success. But his loc and stitch set used 1/8 inch steel pipe thread plugs. That way the plugs “ wedged” in to the metal on both sides of the crack.

I have repaired many 8n Ford tractor blocks with freeze cracks drill the ends of the crack V the crack and braze it. If it seeps after go with water glass. My neighbor has one that I fixed 30 years ago.

 

Back in the day, we wouldn't even wo rry about fixing that. Just buy another bottle od "Stop-Leak" every couple of months and fill the radiator up when needed.

 

Belzona epoxy systems.

Makes JB Weld look like Silly Putty.

I have a brass fitting screwed into a block and it doesn't leak....
