To rebuild a small airplane engine costs about $20,000 and takes months.
You don't want to do it unless you have good evidence that it is needed.

I was talking a top-end. That can be done in two days tops. And a full
overhaul doesn't take months. Where'd you get that? A good mechanic do
do that in 3 days. And many folks get a factory reman and that takes
about two days to do the engine swap.

I was of the impression that a major overhaul was mandated at so many hours
running time.. Was it 5,000 hours, or more?

2000 hours is a typical number. But so what? I would certainly have
an oil test done within the first hour on a new or rebuilt engine.

Only if the aircraft is used commercially. The typical TBOs are 1500 -
2000 hours.
