I agree with Harvey that they SHOULD be high-mileage engines, but not all will be.
For the most part these diesels don't die young, they are killed. Neglect and mis-use.
I have not yet met anyone who had valve troubles in a 3208, I have personally adjusted mine and have not seen anything out of spec. in two FCs neither did my brother in his FC. Early 3208na engines had valve spring problems, this and the possibility of over-revving the engine on downgrades probably led to people believing that the valves are fragile, over-revving (valve float) or a broken valve spring are the only way that you might break a valve, poor valve adjustment would at worst burn a valve which would require head work only.

They also suffer from improper fuel system maintenance, and from general neglect, as to the DD engines, I see as many Wanderlodges with replaced 2-stroke detroits as 3208s. Look it over well, if it is held together by duct-tape and bailing wire it has likely been neglected, and if it has been neglected where you can see it, it has probably been neglected under the hood as well.

Hi Jim,
We just bought our first bird, a 84 PT35 that had a new DD692 put in at 125,000.
The reason was the previous owner broke a radiator hose, the bells and whistles went off and he thought that it meant that he had to take the rig in for servicing sometime soon....trashed the engine.
When I picked it up, the new engine paperwork showed that it cost $14,000 not including labor for his mistake.
Have the one you might be interested in checked by a respectable shop before you buy.
Bob
