6.0 Engine Horrible
I have been told that the excess oil will damage the injectors over time due to the pressure, etc. 80,000 miles in such a short period of time could result in a lot of wear.
I am having the oil changed every 7500 miles, fuel filters changed every 15K miles, along with the recommended changes on the trans and rear end. I run #2 diesel which I get at major truck stops. I never fill at a small station and I have a large aux tank so I don't have to worry and can plan my fuel stops. I have never asked what type of oil the dealer uses, I assume they use the correct type. I do use Howes fuel supplement at the recommendation of my dealer to help lub injectors. As they told me they are so concerned about fuel mileage they tend to lean them way out?????????I don't know what that means. I was told that Ford's policy of just replacing the bad injector does not go far enough to solve the problem. They don not adress the problem of the weak injectors that have been pulled down. They should at least replace the whole bank. Ford does not allow that.
I realize the wheel bearing issue is new, however anyone driving a new 2 wheel drive should be made aware that these bearings need to be checked around 20K. My first time when I lost my wheel was at 59K one thousand miles before ford even recommends checking them. The left bearing were fried and melted to the spindle.....We check the right side and they were out of grease. The other interesting issue was the right bearing was rusted. I have and can not get any one from Ford to look at. Bearing were on the way out again in another 29k miles. The dealer replacing the injectors check them because I had asked them to and the Ford grease had already broken down. Them most frustrating this is that Ford will not even Call me back or entertain the idea of a by back...........I have 3 GM who feel this should have already been done, but that has gone on deaf ears. For those who say that this is the wrong truck that's bull. There are many 7.3 on the road with 500K miles plus as is the case with the Dodge and the cummins engine, which by the way both the Duramax and the Cummins will run circles around my 6.0 and get better fuel mileage by 2 to 4 miles loaded and 5 tg 8 mpg empty.............As I said earlier this truck has never pulled over 12K pounds and most of the time around 8K, which was what I was pulling this load............Yes I am mad, this truck should run much better. If it can't do the pulling they advertise then there is something wrong. As I said before I love the styling and the ride of the truck, but when it comes to the engine and drive train it has major problem.............Yes I can say I know of many problems, my company alone has over 1000 drivers with Dually's and there are probably 20 more companies with almost the same. Whay so many problems, I am around people who work with their truck, not just drive them to and from work, lake, or pull a trailer sometimes.
Extreme use or extreme abuse? The fuel in your oil did extensive damage. Engine was replaced. Someone changing the oil would notice a high level of fuel if properly trained or were around diesels.
Original and stock......eeeehhhh.....I am having a hard time believing this one knowing the business your in.
Everything you stated is showing a pattern except the high rate of injector failures.
Ford offers a 100,000 mile warrenty. At the rate your putting miles on this super duty.....I think it is extreme abuse.
I would buy into a class 6 truck. I know guys pulling hot shots, expediting, and contract hauling. A 1 ton truck is abused very much.
Make SURE it does not have any Alchohol conent- this will absolutely, t-totally vaporize injectors at an alarming rate...
My main point is that something is CAUSING the injector failures; they are not failing on there own. 14 injectors do not fail from chance or faulty parts. The 04 and 05 injectors have very, very few issues. At work we have seen no more than 2 trucks in 2 months with later 04 and any 05 build date brought in for injector issues; one of these trucks admittedly had swallowed a tank of fuel partially contaminated with gasoline (to what extend I do not know).
Do not take it as thought I am blaming this on a operator problem- I am not. However, the cause of this needs to be determined. Injectors will continue to fail if the problem is not resolved.
As for "leaning out", you cannot lean out a diesel (at least not in the respect of doing damage)- if you will notice, when tow/haul is engaged and you are coasting down a hill- the injector clicking will stop- there is NO fuel entering the engine.
My best honest diagnosis without looking at the truck (and this is just speculation) considering a general lack of power, along with excessive injector failures, would be air entering the fuel system somewhere from the tank to the fuel rails.

We all use our trucks. Hard to pull a trailer with a VW. I do not expect a living from mine as you do.
All your problems with the 6.0 is injector related, now if we can get a reasonable answer what your doing. We know the new injectors have no problems with failure rates as high as you have.
Long block...short block...got a barrel of methanol around you pumped into your truck? On mechanical pump injection I used to use alcohol in the winter, but not on these newer trucks....
