OK . . . I know that most threads about the EGR are about deleting it, but I'm actually trying to put it back together. When I removed the old EGR valve to test it, I broke the cast iron at both ends. Hasn't anyone ever heard of anti-seize? Anyway, I was able to restore one side by painstakingly chiseling out the cast iron, but the other side is impossible to fix without destroying the female threads. I have looked everywhere online but can't seem to find a replacement tube (exhaust manifold to EGR valve). I don't want to grab one from a junk yard because I'm sure I will break the cast iron again. Does anyone know where I can find a new one? Engine is a 3VZE in a 1992 4Runner.
