03 f350 6.0
The 03-05 trucks have the worst rap outta all the 6.0s. Mainly electrical issues and the worst of the EGR cooler/oil Cooler issues. So long as its been taken care of its not a big deal but beware that it can rack up expenses real quick when things start going wrong

The 03-04s have a much better EGR cooler than the 05-07 6.0s do. All the 6.0s have the oil cooler issue. The 05-07s have their own set of issues that the 03-04s do not, such as the STC fitting on the HPOP.
Known problems are that the oil cooler clogs up, takes out the EGR cooler, then blows the headgaskets.
When you look at a used 6.0 take a good look around the degas bottle and make sure that there is no white coolant residue present. If the headgaskets or EGR cooler are bad the truck will puke coolant out of the degas bottle and leave white residue after it dries. When you take the truck for a test drive get it all the way up to operating temp and then get on it to see if it will puke or not.
One of the best tools you could buy to help you search for a used 6.0 is a scangauge II. Hook it up to the truck and monitor the oil temp and coolant temp while you drive at 65mph for at least 15 minutes. If the oil gets 15* hotter than the coolant then the oil cooler is bad. It's an expensive repair so you could either pass on the truck or use the issue to help you negotiate.

Like he said look for white residue around the degas bottle. Its a clear sign the truck has purged coolant and that can mean head gaskets. Ask the guy for maintenance records and whatnot. Dont be afraid to open the truck up and let the VGT flex. These trucks like to be worked, not babied.
Also Ryan, Didnt these trucks have an FICM glitch. I heard the earlier ones did?

Unfortunately the 6.0 is a pretty silent beast until it's too late. The 6.0l has the reputation it does because 'it sounds pretty healthy' until all of a sudden the owner is stuck with a $4000+ repair bill. You NEED gauges on these trucks or you won't know there is a serious (preventable) problem until there is nothing you can do except hand your mechanic your life savings.
Agreed. 7.3 runs forever. Takes a bit more work to get decently quick or better for towing a huge load but a great motor...Or buy a 03' up dodge cummins. 98-02 24v pumps are crap and more expensive to buy or repair.
^yea x2 i have only seen a couple 7.3s that are babied...but someone has it already or id have it lol...its a 97 F350CC 4WD with 45K miles
truck is pristene! and my uncles 99 F250 7.3 lol but thats it

I agree with this. If you're seriously looking into getting a 6.0 then get a scangauge or Insight before you buy the truck. It's the only way you'll know the true condition of the oil cooler. Without it you could be buying a truck that's in immediate need of repair without knowing it.
