Hey all, I had an 03 crew cab 6.0 and I sol it a while go because it was wore out. Had 270,000 miles on it. But now I'm looking at 2003 6.0 F250. It has 209,000 miles on it and it looks good but it's cheap! He only wants 5 grand for it. He said he's selling it for his company. It was used or an engineering firm. I asked what it has done and he sai the only thin it has pulled was a couple four wheelers in a small trailer. It seems like a good buy but I like hearing feedback from other who own 6.0. I had bad luck with the first but I was a ranch pickup and wasn't very well taken care of. I'm going to look at it today and see what it's like. Let me know what you guys think I appreciate it

 

Find out if the heads have lifted. The 03 was better about this than later years, but it could still have happened. The symptom is vomiting coolant out the pressure cap on the coolant reservoir. There will be visible evidence of this already on the truck, unless it's been cleaned. To make it happen again, subject the engine to a sustained period of high power, like quickly climbing a tall hill or bridge several times.

I'd also want to know if the injectors have been subjected to years of low fuel pressure. If they have, you'll be replacing them soon. To find out, you'll need to measure the fuel pressure at the filter bowl while the engine is under high load... so, a port adapter, hose leading into the cab, and a pressure gauge, at a minimum. (I know, what a hassle.)

Make sure it starts easily when stone cold, and also starts easily when warm, and also when hot.

 

6.0s aren't prone to just "lifting heads", a stretched bolt and blown gasket/warped heads all start from issues with the cooling system and/or tuner abuse.

Flush the fluids, change the filters ON TIME with OEM and drive it like you stole it

Best insurance is to bring a scanner with you (Highly recommend scangauge II) and read the FICM and Deltas on a decent test drive up to full operating temperature

 

He said te only work that has been done to his knowledge is regular maintenance

 

209K Miles on an 03' with a stock HPOP is just borrowed time in not mine, but a lot of peoples opinions. Seeing as you said it has only had maintenance.

They don't break from under-maintenance, 03' HPOP was prone to failure

Sounds regularly maintained though, that's a +

 

Yeah it sounds ok. But I'll check it out in an hour here. My 03 never had anything done to the HPOP and it had 270.000 I it. I'll ask the guy and maybe he has records of work.

 

get a scangauge ii programmed, hook it up, and take it for a good drive to get it up to temp and see what you have. EOT and ECT split, FICM volt, ICP, IPR, look for Degas puke. You'll want to be the one to start it first thing in the morning to check it's starting conditions. You can search on here to get the specifics for the above items to check. Good luck to ya.

 

X2 on that.

 

Sounds like you should be the person of best advise. 270,000 miles, not well taken care of, and issues? Not much to add here.

HPOP for starters. Spend some money on maintenance and it will be well invested.

 

It had a lot of issues. Jut injector issues. Put one set of head gaskets in it with bolts by the dealership and about 7 sets of injectors it's whole life. Just normal ford ones. It was never really upgraded. Just ran. And when it quit. It got fixed with average ford parts. It had a tough life. Flatbed on I and used it to haul. At 270,000 I still popped the intercooler on it hauling a load of bulls of a hill

 

Sounds like a lot of bull... literally.
