A comment about John Deere diesels and cavatation. I rebuilt a lot them back in the 60s,70s, and 80s when working as a Deere mechanic. For reasons I cannot explain, I never saw cavation on engines being rebuilt for the first time. Yet, once rebuilt with new sleeves, pistons, etc., the next time they're torn down (hopefully 10,000 hours later), the sleeves were full of pin holes. That's around the time that Deere and other manufacturers started recommending some sort of coolant conditioner.
I wonder sometimes what exactly changed? Metals, fuel, ?? God is angry at tractors? Deere engineers told me that higher horsepower and torque ratings cause the increase in cavatation - which to a degree is true - since cavatation is caused by harmonics and vibrations causing bubbles on the liner wall. But, why, let's say, would a John Deere 450 not cavatate with it's first sleeves, but do so forever after once it's had it's first rebuild?
