The Goat on Crack(s) Options

[The Iron Goat]

Soooooo.... pull of the ole highly ported 14b from Goat's Bane, and what do I see? Several large cracks staring back at me. Not just the little one's you normally find around the wastegate.... oh, no... huge monsters that go all the way throught this thing. Not only that, but this thing has been over-ported beyond the opening in the gaskets: recipe for air turbulence and trouble if you ask me.

Now, since cast iron can't be welded, I turn to chemical options. The best epoxy to be found was rated to 300 degrees, JB Weld was rated to 600. Not too bad, but I wanted something better. So I found a solution from Columbiacoatings.com that's right up my alley (waaaaay up my alley, if you know what I mean ) It's called high-temp LabMetal. Can be drilled, tapped, all that good stuff. Also heat rated to 1000+F. Perfect for my 14b. So can you smell what the Goat's cookin'? Thought I would share. Pics and full report to come.

The biggest problem with welding cast is the strength of the material afterwards. I had an old toyota truck ex-man welded back in the day by a guy that did it all the time and used the nickle rod with preheating proceedures and all. It worked for the time I had the truck, but that guy wouldn't even guarantee that it would not crak again. It's a roll of the dice, but the ex-man is not structurally supportting much weight and that helps.

Yup, I weld it all the time at work. you gotta preheat it, Stick weld it with a nickel rod, and hope like hell it dont crack again!
