Not much of a advantage when you have to strip the block and have the cracks welded at a welding shop. The last one I did it ran into a 600 dollar repair.

I rather like them, real easy to work on.
I use oxy so have now mastered the art of welding the "Kohler Krack" in situ, engine in place.
Took a while to work out a technique I have been using a steel blanking plate while welding and am going to try the next one without disassembling the engine.
And yes Kohler stared putting locktite on the front 4 bolts and the problem went away.
It was most likely due to some freak resonance at just the right frequency to unwind the bolts.

I just never heard of oxy welding? If I was to try to weld a aluminum block it would be such a mess it would be junk so I leave that to the professionals that do that for a living. My guess is that the crack would have to be cleaned to weld it proper? I know when I am over my head in a repair. I just bought a mig welder and as I understand it should be able to weld aluminum but I wouldn't experiment on the customers money with it.

Quite the opposite.
Oxy ( gas) welding is a slower process so fluid contaminates boil off and solids float to the top of the weld puddle.
Electric welding is a fast & violent process so any fluid contamination instantly vapourises and blows the weld out of the crack.
Plain physics liquid oil to gasious oil at 1800 deg C undergoes a massive volume expansion which if in a confined space would be called an explosion.
These tiny explosions blow the filler metal out of the weld pool so you end up with a poxy weld with a lot of splatter and bad penetration.
I can do field welds on alloy decks with no more surface prep than to knock off the grass underneath to avoid starting a fire.
We have 3 locally made ride ons which have a cast alloy deck and these are prone to damage from rocks.
