My header on my 99 3rz taco was cracked completely in half.. i just welded it up with my arc welder.. hasn't cracked yet but i havent put enough miles on it to make it crack again BUT.. I head from a Toyota guru back in my home town that sometimes the 3rz's have a problem with them running lean? says maybe its running lean which makes the manifold hotter whch makes it easier to crack.. sounds like a legit explanation to me?
