Engineered obsolescence? Just crazy that they don't do it "right." Sean used a socket and the press to make the freeze plug 0.015-ish bigger and a little import grey RTV...

Once that stopped leaking and a test drive found the OTHER steam crossover tube didn't seat well enough so trim the bolt a little and tighten it up. He drove it home last night. All in all not too bad a project all things considered.
