I started another thread about shopping advice for a used Super Duty. I was advised to stay away from the 6.0 diesel. What exactly is the issue with that motor? It looks like the only reasonably priced used SD's have the 6.0. If it's just power, I'm not too worried. My trailer completely loaded is only around 8000 lbs. And I will only be using this as a tow vehicle. I have a daily driver. My current F150 only gets about 5000 miles/year.

 

My brother-in-law bought a 94 model I think, and loves it. He uses it to tow the camper, and daily driving. No experience with one myself though.

 

The 6.0 reallly got a bad rap when they first came out in 03 because they had what Ford called catastophic engine failure. They would blow head gaskets and EGR coolers which would also take out the turbos and I believe they aslo had wiring issuse with the harness. They also like to eat fuel injectors which are not cheap at about $250 a piece. The 05-07 models are better but are not with out their own issues they still like to eat injectors and are prone to blowing the EGR coolers as well as eating turbos. The later 6.0 will also blow head gaskets but were not as prone like the 03 and 04. I am sure that I am missing something and someone will chime in.

 

Face palm.

If you're willing to spend $3000 on a headstud and EGR delete, it'll be a very solid motor.

 

I have a basic knowledge of motors at best. What is an EGR? Is a head stud something that helps prevent blowing the head gasket?

 

EGR= Exhaust Gas Recircluation Vavle

Head Stud= Replaces the stock head bolt and prevents lifting of the heads when you tune the engine.

 

The 6.0 has plenty of power, but it has been a maintenance nightmare. If you buy one, hold back 3 grand to do what needs to be done, and live with high routine maintenance costs. If I couldn't afford a 6.4 or wouldn't take an older truck with a 7.3, I'd get a V-10 gasser.

 

So if you dont plan on tuning a 6.0 and it is strictly a daily driving street queen would the head studs still need to be re-placed. And which is better an EGR delete or blockoff

 

I have 149k on my truck and it has the stock head bolts. The previous owner used it as a work truck and tow rig for his buisness and towed a 5er with it so I would say no. As for the EGR I would do a delete.

 

If your still in the 5 year/100k powertrain warranty will they fix the common failures. And if your not in the factory warranty anymore, will a extended warranty take care of those problems. i.e gaskets, studs, injectors, turbos and so on..

 

Wow, congrats. You not only missed the introduction of the 6.0L diesel by 9 years, but you don't even have direct experience with the diesel you're talking about. The 6.0L came out mid year 2003. Heres a suggestion, actually know something about the question being asked before talking.







If you are still within the 5yr/100k warranty then yes they will cover repairs to the engine. Each visit to the dealer will cost you a $100 deductable if you are out of the 3yr/36k warranty. If you're out of the 3yr/36k I don't know if you can upgrade to the 7yr/100k warranty. You would have the option of an aftermarket warranty company, but those are shakey at best.

Keep in mind though, that if you do an EGR delete your warranty goes poof. Depending where you live you may not be able to pass the coming diesel emissions test. The head studs themselves isn't covered under warranty, but if you have blown a head gasket and buy a set of studs on your own and take them to the tech doing the work they will sometimes put them in for you in place of the bolts.



The later (05-07) 6.0L engines are indeed better, but its still a 6.0L. At work we have 4 service trucks with the 6.0L. Two of them are 03 F550s, one is an 07 F550, and the other is an 07 F250. The 250 still runs good since it never gets hooked to a trailer. The 07 does ok, but this year it wouldn't run in temps under 30*F. Both 03s have been a complete disaster. We have dumped thousands into keeping the 6.0L fleet on the road, but the rest of our 7.3L trucks have not had the same amount of problems. It sucks because stock for stock the 6.0L has more power than the 7.3L does. The 07 had plenty of get up and go, even for a 12k lb truck, when it was running right.

 

Its a bad motor. Not worth it. Its a great boat anchor though

 

I'm only half joking - buy one with a blown motor and do a Cummins swap..........

 

I had an 03' F250 you see in my sig. below with 44's, only thing that happened was a blown turbo but that was about it.

 

some are great some suck, thats about the size of it. it seems completely random. some 06-07's are the biggest piles of garbage ever, some 03's are the best motor the owners ever had. Just maintain them and hope for the best i guess.
