A correllary to these engines would be terminal cancer.

The odds of getting it are reasonably low for the average individual, and, there is very little you can do to improve those odds.

In the case of the engine, I can't think of a single thing other than to keep the revs away from the top of the range. And, this presumes that we know the rods bend due to high cycle fatigue. It's a good theory, and I ascribe to it, but there are those who believe a foreign object gets into a cylinder and bends the rod.
