Re: 8BA block cracked
Mart, I was hoping you’d have a block for Tony as you seem to find them and rebuild them on a kind of regular basis... I’m betting you’ll find one for him!

Re: 8BA block cracked
The tiny crack from the water jack to the head bolt hole is very easy to fix.
The pan rail crack though. WHEW. Sent from my LM-K500 using Tapatalk |

The pan rail crack is another matter and should be repaired if continual engine use is contemplated. The more common repair is through the use of oxy/acet brazing, but, if proper pre-heat and post heat-cool down facilities are available almost any fracture can be welded using cast iron filler material with either TIG or oxy/acet processes. I have used my wife's large ceramic kiln for preparing damaged blocks for welding. This is a very hot, uncomfortable, project and one must be motivated to do it. |

Re: 8BA block cracked
Hey Gang, while I've had some rare or important blocks welded (cast iron, furnace welding), I'm not sure I'd invest in this particular block.
Take a look at the picture that he posted and notice the cracks on the inside of the pan rail. Then look down by the lifter bores . . . not sure there are cracks by the lifter bores, but I'm suspect. This thing obviously had a lot of freeze damage - I'd be looking for a much better block before I'd be investing in this one. 2021-12-10_13-23-18.jpg |

Re: 8BA block cracked
The ones near the lifter look like casting flaws. Hard to tell from the pict.
I agree, though. Time for a new block. |
