I'm considering buying a 1987 F250 extended cab 4x4 diesel. It has the 6.9L engine. It has had these parts replaced/fixed: Rebuilt transmission, new alternator, new starter, new temp sensor, new fuel return lines, and the injectors have been cleaned and reseated. The pickup has 129k on her. Is there any I should be looking for, for future problems along with anything that may not have been fixed?

 

Welcome to the site..

An older diesel,, could be a guessing game..

But a few things that come to mind..

Has the injector pump been replaced? At that mileage I would say it had, especially if the rest of the system seems to have had work.

Glow system control, or plugs?

Radiator and sytem condition?,, they like to split tanks.

Sometimes head gaskets.. (split rads)

Vacuum pump? water pump? ect..


If its been well cared for, documented,,, just look it over good.

 

Well nevermind. By the time I got there it was already sold.
