Block is at the shop, getting all 8 sleeved just to be fully safe. The shop has done IDIs and have been around for a long long time. I plan to just do a full rebuild at this point.
The quote was $1900 and change for all of the machine work on the short block, that might have included the sleeves themselves I’ll have to check. It does not include other parts like pistons, rings bearings etc.What's the damage($$) for something like that? Still have to use the coolant additive after getting them sleeved?

Here the sleeve cost is $110 per hole for the labor.Having the cylinders sleeved isn't cheap.

I believe the answer is yes. Sleeving doesn't remove the source of the problem, just removes the damage it caused. Sleeving is a good idea because you never know how close they are to breaking through, unless maybe sonic testing would show it.
Thought maybe the sleeves could be thicker than the original walls
That's technically irrelevant. The thinner walls of the 7.3 are more likely to break through, but even the thicker walls of the 6.9 get eaten by cavitation. They just last much longer before breaking through completely.
Some people get lucky running their 7.3 without the additives, it's just not a chance I care to gamble on!
Heard it from others that the thinner walls of the of the 7.3 allowed micro flexing that created cavitation, and cavitation wasn't an issue I'm these engines until the displacement was bumped up.
Along with that, was told coolant additive was developed specifically for the 7.3 motor and the 6.9 never had cavitation issues (could be completely wrong heheh)
