Lots to consider there.

There are a number of reasons to rebore.
If the cylinder is out of round, scratches or grooves in the cylinder walls, or just wanting to increase the engine size for more performance.

It will be using oil, underpowered & smoking. By then the whole engine will need overhauling anyway. Modern engines are normally good for 200k+ miles before they are really worn out.

you bore an engine because the cylinder walls have scratches in them. the overbore cuts out the inperfections and makes the walls smooth again so the piston rings don't pass oil and or gas.

never has to, re-boring is when the shave the inside of the cylinders to increase engine capacity ie: 2.0 litre to a 2.3 or something its pretty expensive cause you have to change everything like the pistons and the seals and what not
