2008 Ford F450 6.4 Diesel issues?

[Tank]

Soooooo, I'm searching and searching for another diesel truck. Found an 08 Ford F450 Dually that is nicely optioned out. I know the 6.0 motor is trash. Did the 6.4 have issues too? I'm a GM / Chevy guy forever so Ford is out of my wheel house but I like this thing and after using my buddies 2015 F250 Diesel to pull the boat last weekend, I started looking at Fords too.

Guy does say headstuds redone and the delete was done.

He also says F450's don't need smog. Is that correct?

Thanks.

Here's the truck

Yes the 6.4 does have issues. I blew a head gasket on mine. I had the 6.0, 6.4, and now the 6.7. The 6.7 has been great for 145k miles now

Yea, my buddy has the 6.7. Freakin trans is probably the smoothest shifting trans I've ever experience while hauling over 10k lbs. Like Butter. And that motor just keeps on giving.

Other buddy has the 6.4 with 225k miles and no problems but the headstuds and whatever else was done on it.

My understanding is that the 6.4 is better than 6.0, but still had it's issues. My concern would be the new rules surrounding registration of commercial trucks being against the rules in CA based on different ages of trucks

 

[79 HUSTLER]

6.4 is a time bomb. Worst truck I’ve ever owned. Great power when it ran though. 10mpg unloaded or loaded with 15,000 pounds. Needs at least one more gear and the mpg would have improved dramatically.

 

[Albert]

I had 6.4 issues for sure

 

[Riverbottom]

I have a friend who bleeds Ford Blue. He had 3 new 6.0 trucks which all let go under 70,000 miles. So he buys a new and improved 6.4 and says that will solve the problem. At 50,000 miles he looses two roller lifters and takes out the bottom end. I think you need to stay away from the 6.4's

I didn't even think of that. Good call.

Ok, so now I'm hearing from a few sources the exact same thing you're saying. Something about the whole front end of the truck needs to come off to work on it too.

Good reading on whatever you decide. http://powerstrokehelp.com/6-4liter/6-4_main.asp

I decided to keep my 6.0 and head stud it, 5k was cheaper than a new truck.

Yea, this is the type of info I needed. LOL Figure if the brain trust of RDP has seen enough issues then it's prone to it.

I'm really trying to avoid issues. I don't mind higher mileage mid to high 100k, but I need to get to havasu and naci and san diego and shit pulling the boat safely there and back with out issue. And I aint trying to lay down 60k on a truck I'll put 6k miles a year on (literally, it won't get driven often).

 

[tunnel vision]

I went through two motors in 74K @ $17k each

 

[79 HUSTLER]

Mine also had some nice electrical gremlins that decide to lock up the transfer case while towing 18k around 70mph. Took out the transfer case, transmission, front/rear driveshaft, and engine. It did add a nice huge vent into the rear floor to help cool it I guess.

See and everything I hear and see is if you head stud it (6.0 or 6.4's) they're golden. This ones been done.

On the 650 or the 450?

That sucks balls.

Yep front end and cab comes off. Although you do get pretty proficient after awhile with a car lift.

 

[prosthogod]

The 6.4 was a knockoff of the 6.0, so yes many issues, not to mention I replaced 3 radiators. In 2011 I got the 6.7. Awesome motor. I only have 112k on it and 2 months ago 2 crank bearings seized and blew out all kinds of parts out of the bottom of the motor. First time I have ever had a catostrophic failure in any of my dozen or so ford diesels. They said it was rare and thank god I had an extended warranty. New engine!

 

[BONER]

@Blackmagic94 blew one up.

 

[Tank]

You guys are basically talking me into sticking with a Duramax. LOL

I really don't understand some of you having multiple Fords with multiple huge issues and keep buying them. I'd have a hard time trusting Ford after the 6.0 debacle.

I should've never sold this truck. Their selling for basically the same price or more than I sold it for with double the mileage.

 

[79 HUSTLER]

That sucks balls.

450. Was just a photo I had on hand. F650 will be listed this winter though with only 1,000 miles on the entire truck. The CAT and Allison is the ultimate setup.

 

[tunnel vision]

My first motor an injector went on vacation, took out that cylinder and piston @ 41k miles, Ford would not cover it because of time not miles. Bought a Ford crate engine (turbo to pan) and had dealer install it 3/100k warranty, that engine let go just barely over the three year mark, with 33k on it and ford said sorry...

 

[cuz_im_CR]

6.4 is the worst motor ever put out in the superduty chassis. I’d take a 6.0 any day over a 6.4.

If you can swing it get the 6.7. I have a 2017 f250 and it is super solid and reliable. I also have an 03 6.0 excursion. It’s a great vehicle.

Yea, I'd buy a cat / Allison 650 in a heart beat. But again, Not letting that much money sit when I'll put 6,000 miles a year on it.

I hear that. This 650 has averaged 71 miles a year. Too many trucks I guess.

Yea, I like that 6.7 package. A lot!

 

[Blackmagic94]

Tank don’t get a Ford. Ask me how I know lol

 

[Cobalt232]

We have a 2009 F-250 with the 6.4. Owned since new. My wife either drives it 2 miles to the office and back, or we drive it to Colorado or the River. 95K. Change oil every 5k without fail. The only issues in 10 years is we had to replace the radiator hoses due to the originals only having one O-ring and a 4WD solenoid and vacuum tube. When it hits 100K, will take it in to have every fluid changed. Have thought many times about getting a new one with the 6.7, but will probably just wait for this one to die. Overall, it's been a great truck.

As said, the 6.4 has its own host of issues. I did a delete on a friends, the truck was actually designed to be worked on with the cab off (ford made that cab a quick disconnect).

And if you towed with a 2015 6.7, those got a bigger turbo and more power than the previous 6.7s so that especially towed well. The 6.4 wouldn’t be in the same ball park.

Buy this instead. Better turning radius, better towing, better gas mileage than a 6.4, and A LOT more thumbs up going down the road lol.

So I spent 4 days in a 6.7 last Month. That 6.7 was so gutless IMO, that I wouldn't even consider one.

Am I alone on this?

 

[Backlash]

Get an older Dodge 3500 with the 12 valve Cummins and save some money. Not the best looking trucks on the road, but they won't leave you stranded either.

I was impressed with how my buddies 6.7 F250 pulled the Cigarette. no problem up steep grade. The tranny was the smoothest I've ever felt. Drove like a dream towing 13k lbs.

 

[rrrr]

I bought a new F-250 King Ranch 4X4 in 2008, sold it at a loss 7 months later. It was a gutless fuel burning POS, and I figured it was only a matter of time before it blew up.

I traded in a 6.0 Excursion that had just 35,000 miles. Shoulda kept it.

09 F250 6.4. 180,000 miles. My trruck has EGR delete, regen delete and S&H tuner. Only issues to date was cracked radiator and exhaust pipe on back of motor cracked. Just pulled 7000lb trailer to Mammoth from San Diego. Held 70mph whole way at 11.9 mpg

 

[DGRAY75]

buy a 2011 or newer f350-f450

Get the 6.7 Tank.

 

[RogerThat99]

If you go on Powerstroke forums, the 6.4 is the worst of the powerstroke engines. The 6.0 is good with a bullet proof kit (which many already have). I have heard the 6.7 is a great engine also.

Ever notice that every 6.0 and 6.4 you see for sale often says “bulletproofed last year” or “just did head studs”....

People still sell em after studding and deleting them, cause often it is not a “fix all” for the shitstorm of other issues they have.

I’d pass on that 6.4, everyone I know had major issues. The consensus is that they are just as bad, if not worse than the 6.0s, and people actually prefer to bulletproof the 6.0 over the 6.4. The 6.4 is often referred to as a “throwaway motor”

The new carb rules does not effect the 2008 f450. As a matter of fact you don’t even smog them.

I would love to do this, but we get smog check every 2 years. Do you have it registered where there is no smog check? I have a feeling our DPF has been cracked for at least 40k as we get a ton of soot in the exhaust pipes.

I have mine registered in Havasu so no smog. It runs so much better after deleting everything.

No it’s a piece of shit also. We have a fleet of Fords at my work (pipeline business). The 6.0 was trash as was every motor after that. I’ve spent more money recently on a 6.7 company truck then I would be able to afford if I owned it. POS had less then 60k on it. I told the president of my company we could make more money if we didn’t have Ford diesels. I now own a LMM Chevy after being a Ford guy my whole life after the 6.0 debacle and what I see at work. I did love my 7.3 though.

 

[Riverbound]

I was looking at a 6.4 450 and talked to my service guy at ford who does our fleet stuff. He said run from it and not buy a 6.4. The 6.0 can be fixed according to him, but the 6.4 is junk. I have a 6.7 daily driver with 190k and it’s been a great truck.

I have 7 friends with the LMM all have blown there engines under 100K.

I had a smog guy. That ship has sailed. 1 year left until I register in Havasu, AZ or sell for new. Switching drivers license as well over to AZ

Sorry that happened to them. I don’t get into the pissing matches on here, just stating what I have expirenced. Everyone has their opinions and experiences with different trucks. It’s all good. I just wish they could all make good trucks without lemons and each company own up to the fact a problem exists with certain aspects of there design or problem areas on the engines. Folks spend a shitload of money and shouldn’t have to deal with them for a long time.

I do t want to spend that much! Like I said, I’d by greg Hariss’ f650 in a heart beat. Things clean. But I don’t drive enough to justify that price tag.

I personally think they all do make good trucks but things can happen with any of them. I think all of the motors in the diesel market are pretty great.
