Sprayed some PB Blaster quite liberally from the inside, let sit several minutes and no seepage. Hit the manifold with a propane torch for a few seconds from the inside, still no seepage. The metal is pretty thick right there, so I don't think it's through.
Would you suggest just leaving it as-is? Or file into it a bit?
