I’ll try and keep this short. I have a 05 f250 with 146k miles. I love this truck and have had no issues in the 3 years I’ve had it. I needed a long bed Dually and found one identical to my 250 so I bought it. It says it has 147k miles on it and is relatively clean. Anyways it has a rough idle. I took it to my local power stroke shop and they went over it. He changed all fluids and filters and added rev x… told me to drive it and see how it runs and if I decide it’s worth investing in come back and he will do whatever we agree on.

I use my trucks to tow, but I don’t drive them much. Maybe 5k miles a year.. but when I go somewhere, I want the truck to run and not have issues.

As of now the engine is “healthy” but runs rough. Like weak injectors or Stiction. It also leaks oil from basically everywhere on the motor.

Shop quoted me about 11,500 to pull motor, reseal, studs, machine heads, lifters, oil cooler, and maybe some other small things that normally go with that.

we also talked about new engine and injector wiring harness for $1500.

$1900 for oem injectors.

how does that sound ? What would you do given the info you have. Part of me thinks for the amount of money I should just put a long block in it. I don’t mind spending the money it needs but I also don’t want to throw money away. I’m not worried about resale value. I probably over paid for the truck because I wanted it.. I’d like it to last me at least 3 years. I’ll probably bite the bullet and just buy a new one in 3-5 years.

 

I have a 03 F250 5.4 with 230K miles on it that I would take anywhere.

Not a diesel but how I keep it reliable is by spending lots of money on preventative maintenance. I put in a reman engine a few years ago and did it myself for about $3,000 newer Diesels are crazy expensive to maintain

You just need to decide if you are willing to spend what it takes, nice looking truck, cost a fortune to buy a new one like it

 

A 6.0 will absolutely drain your bank account if you can't do the work on it yourself at home. They can be made to be reliable, but they require a decent bit work to get them there and they are not tolerant of neglect at all.

IMHO, the 6.0 and 6.4 years of Ford diesels are to be avoided, maybe not "at all costs", but unless you're getting that truck for less than half the book value, I'd walk away and not feel bad about it.

The truck itself looks clean, and based off of your experience with your F250, it appears you're pretty familiar with the 6.0. With that being said, the motor that's in the dually sounds like it's got a LOT of issues. I would either get a new 6.0 put in it, or put a Cummins in it.

 

And that's exactly what I did to the previous 6.0 (a 2005 Excursion) and previous 6.4 (a 2010 F250) trucks I still have, put Cummins engines in both of them. IMHO the best way to go because the rest of the truck, aside of the engines in the 6.0 and 6.4 year trucks, were freaking great.
