I thought he meant it was causing a bending moment, and not a twisting force....at least that's what I got from a prybar type situation. :eh:

Stress concentration...it's all coming back to me.

There are many different kinds of aluminum and teh guy I gave it to can figure out if was done with the right stuff. I also want to do some dye penetration tests to make sure the other welds haven't been compromised. If it blows apart again, I'm going to have custom end tanks made. I like the core. It's an extruded-tube core.
Thanks for the comments. I feel less crazy. It's hard to diagnose this in a car that only builds boost when you're driving. You can't easily see in the engine bay when that's going on.

I did however learn about the fact that an aluminum weld is weaker than the material being welded.

That could do it.
