Diesel Lifespan?

I'm always looking to get back into an F-series again and I was wondering what a reasonable lifespan would be for a stock, well-maintained 6.9L. Any descriptions of what to look for when checking out a truck would be appreciated as well.

No one has any idea how long I could expect a late 80s, early 90s 'Ford diesel' to last?

I would say it is pretty much a guess. My dad bought his new in 85 it blew up after 130K he was very good at keeping the maintence up on it. I had a friend that had a 84 and they got 350K out of theres before it went.

If a diesel is properly maintained, instead of just changing the oil when it gets thin, it is possible to get many hundreds of thousands of miles out of it. However, not babying the engine, and keeping levels constant and fresh will cause excessive wear on the engine, and significantly shorten it's life.

The powerstroke could be expected to run for 400K miles, if treated well. There are plenty out there that did not get much past the 200K mark,because of lack of proper maintenance. I had an old perkins engined truck with 500K on it, when I sold it - still running strong.

we sent a 6.9 to the bone yard with only 240,000 on it. Not because of the motor. We sent it down cause we lost another tranny and the van had a realy bad case of ford cancer on the body. (some nice holes in the floor were good for fresh air) Anyways we took of the one good head and injector pump for spare parts for another 6.9 we still have.
