These numbers just indicate a high mileage engine. The good news about driving a diesel, when it gets tired, as long as it has enough compression to start and run, and you can carry enough oil with you to get where you're going, you can still drive it.

With a gas engine OTOH, when they get tired to a point of sucking oil, then they foul spark plugs such that you can no longer drive them.

If these were the compression numbers on a medium mileage or recently rebuilt engine, they would be alarming. In the case of an old diesel, they just come with the territory.
