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.

I see EGT readings on my EGT gauge of 1500*
Thats a little more than the 1000* rating of the "glue".
Id start with a new housing instead of chancing it coming off and going through the turbine and chewing things up.

That's something that I was thinking about. The EGT is a measurement of the air's temperature, not necessarily what the manifold itself is reaching, so there's some variance there. Also consider the slight heat shielding that the ceramic coat will provide, and the fact that it's rated to OVER 1000*. It's specifically listed to do exhaust repairs, so I'm comfortable with it.

Rob, PM me some more info on that housing you've got. It might just be easier to start fresh than go through that whole process, but I am curious to find out what that stuff can hold.

And I've had several people tell me that you can't weld cast. Don't know from experience, but apparently they do.
