Industry cares about it's equipment, so they employ proactive maintenance, proactive maintenance principles, and proactive maintenance strategy. When you mention anything like this in a car maintenance forum you will get squawked at. But in say a tractor forum or a machine lube forum it is the rule, not the exception. People using expensive equipment not only use uoa's to see the wear, but actually mix lubricants to address problems, GO FIGURE? Find out how the equipment is wearing, add known principals to the lubrication formulas, and have a maintenance strategy including interval, pressure, filtration, etc. It is the spirit of those principals why so many ram owners have literally fixed their issues. You can call it something different if you like, but it is indeed about problem solving just like in industry. If an industry machine needs a cleaner, they use a cleaner, if they need AW/EP additives then they add those, if they need base oils they will even add those. That isn't me talking but machinelube, it is in every paper over there.
You already started this process, you learned about it applied a strategy (cleaner), likely benefited from it, now you need to adjust your strategy based on principals, to fix a problem. If you had a million dollar piece of equipment you already would have adjusted your strategy, so treat your truck just as good as they treat their stuff. You have hemi tick and elevated wear with some shear hinting that mechanical shearing is happening, so there is no known date when cam's fail, just that they often do here, I would save as much of the lob as I could with those principals, good EP additives and hths.
