Well, you have not said anything crazy in this thread, but the usual argument of the "steel will last forever crowd" is that steel has an infinite fatigue life, assuming design parameters are not exceeded. Engine vibrations are surely well within the design parameters. The problem is, that the "steel is magical" crowd doesn't take into account the fact that potholes, and the like, may not be. Especially with modern, light n sporty, steel designs.
