Some engines, especially some older ones, don't have the problem. The errosion and cavitation is accelerated by harmonics and high horsepower. So, many older engines that were over-built rarely had the problem. And, so light-duty smooth running engine also do not have the problem. The issue also has to do with engine design in general - some engines make more vibration than others - and are more prone to cavitation. To put it simply - a cylinder liner usually develops a protective layer of rust/corrosion on the surface that contacts coolant. Unless the coolant is high acid, that surface is pretty stable. But, an engine with high harmonics peens that surface with bubbles, and the process starts all over again until there is a hole. It's kind of like picking off a scab.
We had more and more problems with Deere engines as power kept being raised. Deere DID have some early problems with their first sleeved diesels - but that related more to the single-seal design that was inadequate.
Another example is the IH diesels used in Ford trucks. The first 6.9 engines had very few problems with cavitation, but when they got bored to 7.3 liters - the thinner cylinder walls along with increased power output cause many caviation problems.
