Maybe on a Powerstroke, but on an IDI (which is the only diesel you'd find in a bricknose), injectors don't cost anywhere near that much. Couple hundred for a set and a total DIY job.

Thats the guy.

All of the things mentioned are things that I would be checking out if he agreed to the price. Those are good suggestions for things to look at for future trucks



Thanks for the help

Not sure where you buy your injectors from but 2000 gets you a pretty juicy set!

$2000 for injectors?!? Try TWO HUNDRED. a reman IP is like $400. I think kyle is talking about powerstrokes.


OP go to the pre powerstroke diesel section, theyll guide ya well, its a small tight community.
I got a 91 f350 crew long box 2wd manual. love her shes got 450,000kms on her purrs like a kitten. did eater pump and oil cooler and glowplugs as well as starter. Be prepared for those as the seals get old and dried up after all those years. my buddy had a 93 250 with 650kms and no major work.

To check if injvtion pump needs servicing/rebuild soon drive the truck to get it nice and warm, **** it off and restart it. it should start almost instantly. If it coughs a bit-poir some
Cold water on the pump-if it starts then u need a new pump

I would look for rust. However, I have a 94 crew 4x4 7.3 idi turbo with 342,000 miles and it runs perfect. The injectors on these things are only about 250-300, it is the powerstrokes that have the expensive injectors. I think my truck will go another 700,000 miles and I'm gonna try and make it there.

Noticed one bad thing in the add posting he replaced the "left front brake caliper" as in didn't replace both at the same time. Not that this is a terribly bad thig in itself but an indicator of a cheaply maintained vehicle.

And did the return line routing change between 89 and 91 or is there something going on there? The return line from the IP is going to the drivers front injector?

I can afford to make the drive as many times as I need, I'd just prefer to only make it once or twice.

I know that I can afford to drive it. The vehicle i drive now gets about 12-14, with gas being an average of 4.09 a gallon. If i can get at least 17-18 with the diesel, i'll be happy (ave. Diesel price has been 4.25 a gallon)

Pretty sure the IDI's don't have replaceable liners, so cavitation wouldn't be an issue.

he's asking too much for an old 2wd idi truck imho.
the $ he put into it doesn't make the vehicle worth more to anyone but him because vehicles depreciate.
id keep looking,and id suggest a car in your situation.these old trucks require LOTS of work,time,and money.
a small car can get 30-40mpg.why struggle with parts and anything less than 30mpg today for running back and forth to school? buy an old idi truck,and your gunna regret it in your case.
the 7.3l is generally the least of your worries.it's the old truck part that'll get ya lol.
don't forget just because the engine lasts a long time,doesn't mean it doesn't have medium ware items.a tuneup for an idi will still set you back several hundred.idi's are often neglected because the trucks are old,and a lot can't afford,nor are willing to invest half their trucks value for a proper ip,injector,timing set every 100k.presume it's needed for any idi truck you buy today,unless you see receipts proving otherwise.
22-25 mpg (if talking US) is somewhere between very optimistic and a fib.
upper teen averages can be expected on the hwy,running empty.that's if the engine is in proper tune and you keep her under 2k rpm.

No, cavitation is a concern on IDIs, 7.3 specifically. Check out the article FORDF250HDXLT has linked in his sig titled 'maintaining coolant for the IDI'

I undetstand that they're old, may need work later on, and it will cost money. I'm neck deep in restoring my '79 f250. I've spent about 3 grand and the last 2 years working on it, and i'm not even halfway done.

A car would be great, but I can't haul anything. In the summer i mow lawns and landscape, and we are harvesting trees for wood year round. My dads nitro can only tow so much. A mini truck is also a good thought, but not practical for my needs.

Because someone might ask "why not use your '79?", I'll say that for one, it's getting restored, and two, with a built 460 pushing a lot of power, that truck gets about 4-5 mpg.



Thanks
Jameson

I'm not trying to be ignorant but seems like you're contradicting yourself. Also sounds like you have champain taste with a beer income. You just said you owe you're father money and you're not even sure if you have enough money to buy the truck. you should of bought the truck you need for work before you bought the project toy. seeing as you're a student you don't have a full time job. Put you're money aside and keep saving of you ask me. you're always putting money in these older trucks wether its steering or suspension components or whatever including maintenance and insurance. on a side note I wouldn't pay more then 1000$ for the truck.

don't forget about the fire wall reinforcement bracket with the 5spd, the fire walls had a tendency to crack. It would be a good idea to get one installed if there isn't one in it yet
