Even engines can run several hundred thousand hours without a failure.
And
jet engine cores run even longer than that.

Not true. One of the longest running jet engines in service on a commercial
airliner was a CFM56 attached to the port wing of an easyJet Boeing 737 a
couple of years ago which had clocked up about 86,000 hours and at that
point had never been removed from the wing. However, that was acknowledged
to be an exception by a large margin.
