Anyone else have a 6.4L ford diesel?

[Hay Dude]

I have an '08 550 with a 6.4L diesel. Mine has been problematic. Luckily, warranty caught most repairs or I'd be out $3,000+. I only have 52,000 mi on truck. Warranty is nearing expiration (June 2013). Dealer wants 4 grand to extend drivetrain warranty. have already replaced injectors, injector harnesses, LP fuel pump, radiator hoses and a few other things.
Rest of the truck is OK, but engine makes me very nervous. Just got another "check engine" light yesterday. Going to dealer for scan to see what it is this time.
Has anyone had any experience with the 6.4L? Did you extend warranty?
I bought an '08 to jump over the 6L, which I heard was worse, but now this 6.4L has me thinking. I can't believe these problems are still plaguing Ford.
hear the latest Ford diesel is better, but really don't want to buy a new truck.

Problematic engine.

Try a Cummins.

Or Duramax.

Both are available in similar capacities.

The 6.4 was an interim motor built by Navistar to meet the EPA emission requirements. I've had a 1989, 1995, 2000, 2007 and 2011 Ford F350's with diesel motors.

The 6.0 liter 2007 was totally reliable as Navistar + Ford finally worked out all of the problems with that motor. The 6.4 liter was a step backward as Ford had the 6.7 liter in development and Navistar didn't care to support Ford on the 6.4 liter because they knew that after 2010, Ford was no longer going to use Navistar motors.

The 6.7 liter Ford diesel is a really good motor - the best I've had in the list of vehicles I've owned.

The 6.4 was one and is one of the strongest motors ford has ever put in one of their trucks.
The BS emissions is what is creating all the problems with the engine.
If you want it to last you need to get a hold of Spartan Diesel Technologies
I would spend my money on a tuner and a dpf delete before I would buy the extended warranty.
JMO

After Nov my 6.4 will be out of warranty and I am going to Sparten it.
There is a lot of discussion over on the ford truck forums about this topic.

I could not agree more. I have a friend who has a 6.4 F350 and once he did some deleates its a awsome truck. It gained 3mpg also.

As for other branda, the Cumnins and Dmax are both good motors but that is where it ends. The rest of the truck falls well short if the Ford.

I agree with DP for the most part. I had 2 of the "dreaded" 6.0 motors, an 04 and 06 F250. No problems. I unloaded both because, being a rather practical person, did not need that level of power anymore as farming operations were being scaled down. I did not care much for the steering "wobble" of the 06 (4x4) but it was a very confortable truck (Lariat). The 04 was 2wd and rode nice. Several farmers in my area have dmaxs and cummins. A lot of them switched due to issues with the 6.0 and 6.4 engines. From the ones I see on a regualr basis, they really like the dmax/cummins.

My friend owns a landscaping company and has a 6.4 f-450. He hasn't had any problems but the fuel economy was quite bad. When the warranty ran out he tuned it and removed all the restrictive junk and MAN will that thing pull now!!!! Super strong engine and gets very good mpg now according to him. That truck works everyday of its life with no complaints. He's scared of the 6.7 like many of you are of the 6.0 and 6.4.lol

Check this site out. I have the 6.4 just called about extended warranty. They wanted, are you ready for this $6000.00. For the extended warranty.

Some may say this guy is full of bull, but he seems to know what he is talking about. Check out the vids on YouTube of this guy and the 6.4.

I agree and I have a GM with a Duramamx diesel, but GM is no longer available in "similar capacities".
I'd be driving a used 5500 4x4, but it won't fit in my garage.
Couldn't find a Dodge in my price range.

Once you do the "deleates", the truck no longer meets EPA standards. This is a commercial towing vehicle subject to roadside inspection.
I wonder if the manufacturer of the deleates includes an explanation letter for the state police as to where the federally mandated pollution control system went and a blank check for the $3,000 fine?

I'm all for improving reliability for an unreliable Ford engine, but I'm too old and have too much to lose to break the law.

Yeah I forgot GM stopped making the 4500/5500 trucks. I do remember them stating the the dually 3500 was intended to replace the 4500 trucks to some degree.

I've had the full range of Ford diesels from the 6.9 to the 6.7. Never had any problems with any of them. I had an '08 F-450 pickup with the 6.4 that I traded for a '12 F-450 pickup with the 6.7. My biggest gripe with the 6.4 was the turbo lag when you took off from a stoplight. Other than that, no problems. The 6.7 doesn't have the turbo lag and also gets about 5 mpg better mileage than my 6.4 got.

Are you serious about this claim?
5MPG is a lot. I get about 9 MPG from my 6.4L.

 

[yellowdogsvc]

My friend's 2011 f250 6.7 picked up 17mpg highway while my '08 f350 drw with 6.4 only gets 11-12. I was shocked at the difference.

 

[lhansman]

I picked up my 2012 F250 6.7 diesel three weeks ago and with 3,000 kms on the clock I am averaging 16.8 MPG which is almost as good as what I was getting with my 2004 F350 6.0 which had the EGR removed and a straight through exhaust and SCT tuning. I am very impressed with the 6.7 so far in terms of fuel economy and performance.

Completely serious. Both trucks have the 4.30 axle ratio. The '08 would hardly do 12 mpg empty, and that was staying off the interstate and keeping the speed below 60 mph. The '12 will get over 17 mpg driving the same roads and speeds. At 70 mph the '08 would drop to 10 mpg and the '12 will still get close to 16 mpg. These are heavy trucks.

 

[Hay Dude]

I know, I own 3 of them.....lol

I can't get more than 10MPG with my '08 6.4L empty on the highway.
I can't believe that's the best Ford could do just 4 years ago.
I think the 4.30's are a huge help to getting the MPG's up. Even more than the new diesel.

When I actually drive mine ('08 F450) unloaded on the freeway, I get 12-13 as long as I stay under 70 mph.

4.88's on yours?
What's your empty weight? Mine's 9,300lbs

I've read the new 6.7 Ford does real good mpg. I've heard the 6.4 is problematic from people I know; mpg and mechanical problems. A guy that works for me had an 09 6.4 he paid 55 grand for, put 150K miles on it up to 2012, said he spent 15 grand on repairs and traded it in and got 15 grand for it on trade :thumbdown: . Do the math on that one. He got a new 6.7 and he likes it. The 09 was pretty beat though, his 6.7 is getting the same way but hasn't broke down that I know of.


I'm going to hang onto my 07 5.9 Dodge. Has never had a problem in 6 years besides the front end and water pump *knock on wood. The front end is junk, pure junk and I've had to basically rebuild it with quality parts, the water pumps on these go out often and are cheap like under $100 and take only 30 minutes to change supposidly. I know when the dealer did it under warranty they had it done in one morning, had it back in a couple hours.

I also have a 2500HD Chevy 6.0 reg cab long bed. Going to trade if off for a used F150 5.0 reg cab long bed in a year or so. With these new diesels getting poor mpg I wouldn't shy away from a gasser, they are much cheaper if you aren't pulling a lot.
