Sickening- Cracked Block - Repairable?

[zyzzyx]

Nice repair on the broken ear! Yeah, the freeze plug hole is not a candidate for drill & stitch repair.
Weather you use the Tig Tectic filler rod or something very similar I believe welding is your only option.
Have it welded and forget it. It's not in a high stress area. The area just needs to be V'd out and
preheated to around 250, then welded. Don't let anyone tell you any other "Hocus Pocus" B.S. It.s
a straightforward repair. Good luck and keep us in DaLoop!

Just find a experienced welder/ repair shop they will fix it right.. disappointing for sure, fixable you bet... nickel rods are what I’ve always heard also heard preheating the block before welding .. there is a process and it will be fine.

Well... The company Lock and Stitch is just down the road from me, for years they have sold their repair kits & repaired equipment at their facility while also having a crew that travels worldwide repairing cracks on heavy equipment, ships & anything else where the owners were willing to pay the costs... But it looks like in 2025 the company was acquired by Wärtsilä & the new owners aren't selling the repair kits anymore... I had heard something about it earlier this year but now searches appear to confirm that.. Other companies are selling the original design pins, the drill guides don't appear to be available... Though honestly that wouldn't be hard to fabricate..
