View Full Version : Ford Diesel Q's

06-19-2009, 12:33 PM
I know this has been beat to death but I need the ups and downs and ins and outs of a 2004 6.0 diesel. I know they had problems with those motors and was wondering if a 2004 was one of the bad years or what am I looking for as far as repairs and so on and so on. Any and all info is greatly appreciated. Thanks.

Get a Oasis report on it it will tell you most of the repair history on the truck. If the Oasis report is 100 pages run like h*ll the truck has been a problem child. The 03-04 trucks did have more problems but otherwise its been hit or miss.

You have no choice you buy a high mileage worn out 7.3 or buy a low mileage 6.0 and deal with some problems.

You do a EGR delete and head studs with a 6.0 you cured the two major problems. I haven't done either yet with my truck I haven't had any problems but I don't drive my truck hard either.

I would take a 6.0 truck over a 7.3 I like the power the 7.3 can't match the power the 6.0 has.

As I said get a Oasis report you need the VIN number on the truck and get the report from a Ford dealer.

Head gaskets, EGR coolers, radiators, high pressure oil pumps, etc... lol. All years seem to be a problem from my experience.

If you want an OASIS let me know. I'm a service advisor at a Ford dealership. E-mail your complete vin to teklawncare@gmail.com and a fax number and I'll get it to you this afternoon.

Sure, the tabs would be off a bit but it's readable. Go ahead and send it over. I'll be at work another 30 minutes.

I have an 04' 6.0...no problems after 5 years and over 70k miles. Good luck!

I have a 6.0 with 180,000 KM's, no major issues what so ever. Has also been chipped since 80,000 km.

04's were not the best years, but there is plenty of great 04's on the road. As long as the oasis checks out, jump on it.

I checked it. It had some transmission problems, but not anything with the engine.

'05-'07 were the better years for the 6.0, but the 7.3L is a much more proven engine, much more reliable, and will go well over 500K miles if you keep the oil changed often. The 7.3L has PLENTY of power, I can't imagine needing more for anything. I have a '95 Ford E350 van with the 7.3L, and it gets GREAT fuel mileage. It does have a fuel economy chip though. I have gotten 24 MPG when going 55 MPH. It drops to 18 or 19 at 70 MPH. And gets about 18 in-town pulling or not.

I have had both the 6.0 has more power and once you get a 6.0 Grin its hard to get rid off it. The 7.3 may be more reliable but it doesn't hold a candle to the power the 6.0 has. I have had a 7.3 the 6.0 is more fun to drive.

I've driven both plenty of times at old job and to me the 7.3 has the grunt power and 6.0 has the all around power. Never owned neither so I'm worried that I may get a basket case with 6 liter. Think I'm going to follow through and hope for the best. Thanks.

You have no choice nowwadays you have to buy newer the old 7.3s maybe still running but the rest of the truck is showing its age. Why do you want a high mileage truck with a seat that has seen enough methane and a cab that squeeks and rattles.

I took a chance with the 6.0 yes I had some problems but I got tired of looking for a truck with a 7.3. I didn't want a worn out truck.

When I bought my 03 it had 36,000 miles on it in when I bought it back in 06.

I had had to do a turbo and couple egr valves I did have to do other stuff to the truck but that would be the same if it was V-10 powered.

It seems now that I changed out the VGT actuator on the turbo I'am getting the 03 whistle. I guess the VGT actuator was weak and even with a new turbo it wasn't giving me full boost.

I don't dare put a straight pipe on the truck the whistle might be too loud :laugh:

There are still plenty of great 7.3's out there in America. GR's in Canada so take what he says knowing that. Its alot different up there then down here. Just the other day i looked at a 2000 model CC LB 350 powerstroke the other day and it still looked brand new. Only had 94k on it. If you're not in a hurry, start searching and you can find a 7.3 in great condition. 02-03 were some of the best 7.3 years in the Super Duty.

ive had both and ended up selling my 6.0, after going through 5 major transmission issues which cost me over 10k total, turbo, turbo boots, every crevace of the motor has a leak, been nothing but problems, i dont think it was meant to be put in an 05 f550 pulling the mulch blower while full of mulch, yet its supposed to be able to fine
pics of it are on my site, www.silverstreakinc.com/Landscape.htm

if you go here youll learn a lot about both


i kept my 01 f350, no major issues in 141k miles, although it may be needing its first trans in the next 10k miles, and any other repairs ive been able to do myself, not something id try with the 6.0

the 6-oh had some nice power off the line though..sorta miss that, but i needed something that works hard EVERY day never fail
