I've just purchased (couple months ago) a 1990 F250 4x4 7.3 IDI Diesel, extended cab, longbox, auto tranny, with 214k, and a lot of rust, fairly new tires, and bad brakes. Paid $2000 for it which might seem kind of high but it was the best price I could find locally.
Had the brakes and rear axle seals fixed for $600.
Changed All glow plugs from autolite to Motorcraft (autozone $8.50 each) - be careful if your GPs are autolites, they can swell and tips break off in the combustion chamber. Lucky for me all plugs came out easily. Check out Ziggsters tutorial on GP removal:
http://www.members.shaw.ca/k2pilot/Glow%20plug%20removal%20article.htmlChanged oil and filter using a motorcraft filter and Rotella 15w/40. I'll switch to Rotella 10w/30 this winter.
Changed air filter (fram, it was what I could find quick.) I'll replace later with something else.
The previous owner changed the coolant about 15k miles before me but did not use diesel coolant or SCAs. This could lead to cavitation (requires rebuild). So I changed the coolant with the green stuff and added SCAs to the proper concentration. I'm kind of worried that cavitation has started but so far OK. Maybe I'll get lucky.
The previous owner also changed out injectors on one side. Not sure why only one side but it seems to run OK.
Tranny was rebuilt about 35k miles ago. Seems to shift good and tranny fluid is very clean and smells good.
Still need to change the fuel filter, could use new shocks, should extend the exhaust pipe to back of truck instead of in front of rear wheels, and I might need a new Glow Plug Controller or rewire the existing glow plugs (still clicks with the Wait to Start light).
Also purchased a bunch of other stuff for diesel maintenance, i.e. extra SCAs, Power Service, ...
So I've already got well over $1200 to make the vehicle road ready and there is more to spend. So far, my purchase doesn't look like a very good investment. If the engine holds up for a year or two it might be worthwhile and it has been a great learning experience. heck I've spent a lot more money and got less education. ;-)
Good luck and enjoy your truck.
