No offense, but that article's full of holes. Cavitation (liner erosion is the proper name in the real world) has been around ever since there's been big diesels. I can't count how many pitted liners we changed in Cummins NTCs, etc, way back in the '60's and '70's+ due to erosion. Most all heavy diesels had Perry Filters on them to prevent the problem, but many drivers would neglect changing them. If I remember right they were made by Penray, now called Nalcool or maybe Pencool. Coolant additives have been around for decades too.
And the one and only engine I did see in person with cavitation (Ford) WAS a 6.9. It was in about '92 and the truck was torn down in an IHC heavy truck shop. I'd heard vague rumors of it happening and went in to ask the service manager if there was any truth to it. The Ford dealer wasn't aware of it at that time, but I started adding Fleetguard real quick-like. Evidently the 4.9/7.3 Navistars in a commercial application came with a factory SCA filled coolant filter like most diesels but Ford deleted them in the Ford diesel pickups---not good.

A few years after having to replace the engine due to cavitation they sent us a letter in the mail alerting us to put SCAs in our coolant to avoid damage.

Right, and then what frosts my butt, not only was it Ford's screwup, but then they charged people twice as much for the SCA as any local truck shop.
