Ford F-450 with 6.4 diesel

3930dave · Jul 9, 2014

I've been keeping these valves in mind for special applications.

About Fumoto Valves | Fumoto

If you're considering doing some oil testing Buppies, you might want to get one of these fumoto valves for your 6.4 - easy to sample with, before the end of a regular interval.

Thanks will look into this. So far truck is getting about two miles per gallon better than it was before

My friend at the dealer tells me the 6.4 has lots of issues, especially turbos, but the 6.7 is better but not without issues, mostly exhaust add-ons for Nox control that fail early. If you buy new buy their extra warranty, I think it's 5 grand extra.

So sad, it's not just Ford but most OEMs are having issues, choose your poison then pay, Fred

Great thread. Every time I think of buying a new truck, I read some of these repair threads and feel lucky I have an 18 year old vehicle!
These repair bills are scary! I know guys with Ferraris and other exotic cars that spend less.

The thread has cured me permanently of diesel envy.

Article in the new sept/oct Truck Trend Magazine talks about a problem trend with the Ford diesels. It affects '99-'10 F250, F350, F450 pickup, F550 diesel cab and chassis, E-series van, or class C motorhome. The coating on the inside of the fuel tanks is delaminating and sending tiny flakes through the fuel system. It can affect everything from the tank filters to the injectors.

Glad I swapped in a 57 gallon transfer flow tank!!

Thanks for posting that. Sent it to a buddy on the left coast - after he gets through checking the glow plugs for an occasional starting issue, this is something else to consider.....

So, what are they now putting ethanol in diesel fuel too.

Reminds me of all the issues years back with ethanol causing fiberglass gas tanks on boats to delaminate.

I would not be surprised if it's not the Bio Crap.

Ultra low sulfur diesel fuel is what caused the corrosion in (large) storage tanks. It is from cross contamination with ethanol gasoline fuel. If I understand it right, ethanol gasoline contains a type of algae that will thrive on diesel fuel. When fuel supplies are switched from gasoline storage to diesel storage, some gas is left over in the tank. The algae thrives in ULSD and as the algae goes through its life cycle the pH drops to 2.5 or so and stuff starts corroding. Previously the sulfur in diesel fuel acted like a biocide and killed the algae (from ethanol gas). That's my understanding of the diesel corrosion issue.

I believe this is correct. I've seen marine applications where algae was in the diesel. Bad deal.

Everybody has issues but combining the 6.0 and 6.4 problems Ford has everyone else beat in the diesel problems department. I would never even consider buying a ford diesel unless is was the old 7.?? liter. We have 2 of the 6.0's where I work and just ordered a used 550 with a 6.4. Had nothing but problems with the 6.0 and I'm already expecting the same form the 6.4 after reading about the motors. No idea why people keep buying them after all the problems.

Just my $0.02, but my 6.4L has been trouble free for it's 52k+ miles. I did have the radiator replaced due to a leak, but the engine itself has been trouble free. Fuel mileage is nothing to write home about, but with my short trips, I expect that. I can get 20MPG on long trips, and 10-11 towing my fifth wheel. It tows my fiver with ease, whether it's on flat ground or in the hills of the Ozarks.

However, if Ford puts an EcoBoost in the F250, this will probably be my last diesel.

I find it pretty hard to believe that anyone with formal training in oil related bio-chemistry would not have been able to accurately predict these consequences.

I think you've posted elsewhere tpw..... but my lousy memory can't recall......

Do you add any diesel treatments routinely to your fuel ?

I just sold my old camper and my 7.3 Powerstroke...
Did not really want to sell it but did not need as much truck since I was not pulling a 5th wheel anymore...
I went out and got an 07 Chevy with a 6.0 Vortec...
With the emissions issues on diesels I am over with them too...
The 7.3 is a good engine...

I do add Power Service Diesel Kleen on occasion, but not regularly. I have used less than a gallon of it in 26k miles, so it's not very regular at all. :laughing:

I try to run a tank of biodiesel through it whenever I can (the nearest station is 35 miles away, but I do go by it every now and then). I seem to get 1+ MPG better on the tank AFTER a tank of bio for whatever reason.
