These engines have been a nightmare for Ford. Radiator issues caused by coolant backsplash (engine issue, not radiator problem), injectors toasting engines left and right. Heaven forbid that errant piece of dust somehow gets into one of those piezoelectric injectors...goodbye glass jaw 6.4 liter.

Programming problems have been the least of their issues. Ford techs are starting to look back longingly at the 6.0 nightmare as if they were the "good old days." It's almost funny to watch, or maybe just sad, I'm not sure anymore.

Simply put, the 6.4 is hard as hell to work on. Everytime I look at one of these turds under the hood, I just want to know who International was playing the joke on. Apparently it was Ford for being stupid enough to continue doing business with this company after the 6.0 fiasco. Ford should have sued their way out of the Navistar contract years ago.

I hate to see what happens to 6.4 owners when these things are out of warranty.
i dont know what crap your talkin but iv got 46k on mi 6.4 with no problems.i gues you just dont like the 6.4 but you can ask every 6.4 owner here and they al love em,either that or i got a dang good 6.4

Talk to that owner who had his brand new $50,000 King Ranch Crew Cab 4x4 blow up with 600 miles on it.

Go to a local dealer and you're likely to see a couple '08 cabs up in the air because some random thing blew up a 6.4.

Defend your purchase all you want, but it's still a ticking time bomb. International ****ed Ford over again.

Even if you managed to get a decent 6.4, it's going to be reeaaaaal interesting when you get past 100K...or 150K. Pretty damn pathetic for a $8,000 engine option.

The 3V V10 owns this turkey.

1. I'll hook chains to any V10 out there, you see where I am.

2. The new emissions require you to pay attention to your motor and what you feed it. If anyone is capable of actually using the right fuel, oil, warm up and cool down procedure, regen monitoring and compliance, maintenance schedule, AND, My God, look under the hood and under the motor now and then, the 6.4 is a great motor.

3. Women are the ones who say "I just turn the key and it goes when I push the gas pedal, stops when I brake".

YES, I am a little peeved about slamming the 6.4. Don't know why but I'll defend it.

Big Bad, how do you like your CUMMINS. OOPS, or is it a DODGE. Do you have a truck. Come on, with all the wisdom you spew, give us some of your eloquent history. Do you have 6.4 diesel truck, or do you just know it all????????

REFERENCE: HEADS

Cylinder Head & Head Bolts
• The 6.4L Power Stroke Diesel uses a four (4) valve per
cylinder head design to optimize airflow and efficiency.
• The 6.4L Power Stroke Diesel engine uses larger head bolts
than the 6.0L Power Stroke Diesel engine (M16 vs M14).
• The 6.4L head bolts are also slightly shorter than the
6.0L head bolts. The 6.4L head bolts do not retain
the rocker carrier like the 6.0L head bolts do.

Also, your description of radiator failure is TOTALLY INCORRECT. Take time out from your, whatever you do, and you check it out.

BTW, MICROSOFT has more programming issues than the 6.4.

Oh crap!!!! ruschejj you better trade your truck in before the end of the month. Maybe if you start towing in reverse to get your 80,000 + miles to come off the truck it will last longer.

I am all for "opinions" but lets remember that opinions are not facts and should not be presented as facts. So rather than me share my opinion I decided to get some factual data. I looked up the complaints with the NHTSA. For 2008 F250 and F350 there were 52 complaints and 14 of them engine related. First off, 52 complaints in the whole country over a years time is hardly a dent in the number sold but lets discuss the "junk" 6.4 in detail.

1 - complaint for a leaking valve cover (yep, junk engine)
4 - complaints for leaking radiators (can this really be classified as an engine complaint?)
1 - complaint about a broken DPF
1 - Engine needed replaced at 47,000 miles (didnt say why)
1 - excessive smoke from tail pipe (um, read your manual dumb azz this is called a regen)
2 - regen at high idle, 1 of them hit his trailer since he was in reverse (Ford has already fixed this problem with a reflash)
3 - complaints for white/gray smoke coming from the exhaust (again, this is called a regen. Maybe you should have read the brochure, the manual, watched the DVD, or asked your dealer why your diesel truck is smoking)
1 - complaint for lack of power. Dealer replaced fuel filters and problem has not repeated in 5,000 miles (this is called maintenance. It does wonders on a diesel truck. I know your Toyota Camry didnt need them but you bought a diesel truck this time)

So there you have it folks. Whatever you do, dont buy a 6.4. No, not everyone complains to the NHTSA. I did glance at the 2003 6.0 and there were 377 complaints so either this is a better truck so far, or less people are complaining about it.

I have to post this just because its so funny. This is one of the actual "engine" complaints to the NHTSA. Even though the dealer explained the regen the customer felt inclined to complain.

FOR NO REASON SOMETIMES A CLOUD OF WHITE SMOKE POURS OUT OF THE EXHAUST PIPE. THE SMOKE IS SO SEVERE IT WILL BLIND ANYONE BEHIND THE TRUCK. THIS HAS HAPPENED SEVERAL TIMES. THIS COULD BE A DRASTIC PROBLEM IF THIS IS NOT CORRECTED BY FORD MOTOR COMPANY. I HAVE HAD THE TRUCK TO THE DEALER SEVERAL TIME AND THEY SAY IT IS NORMAL FOR THE TRUCK TO DO THIS BECAUSE IT IS PART OF THE EMISSIONS. IF THIS IS THE CASE THEN THEY ARE ALLOWING A DANGEROUS SITUATION TO TAKE PLACE.

Ask any diesel tech what they think of the 6.4 at a dealership that has any kind of volume at all.

You'll leave with your head spinning, I promise.

These engines are being replaced at quite a rate with low mileage on the odometer, and the problems are not related to maintenance either, but rather design flaw after design flaw on International's part.

I am just an old numbers dummy. Please explain. Here is a specific question:

To your knowledge, how many engines have failed, requiring replacement engines, 6.4 engines, in FORD Super Duty Trucks, with less than 50,000 miles?

Same question, ...with less than 100,000. miles?

Truthfully, I found so few "qualified 6.4 diesel techs" in Ford dealerships, such that, they are always busy, as compared to techs working on other FORD/Merc/Lincoln vehicles.

I know of at least 20, full blown engine swaps. Not including pulling heads, injectors and EGR coolers. They are in the shops all of the time.

I was in three major shops in central GA the last four weeks and did not see a 6.4. I did see a 6.0 with 250,000. for a turbo.

Big Bad, you don't show where you are located. You really should complete your profile. I have seen a few guys and gals speak to some of your comments as that from a TROWELL, but I know you are not that.

Please give us some FACTS...

I am sorry. I didn't even know how to spell it, but what I meant is as follows:

An Internet troll, or simply troll in Internet slang, is someone who posts controversial, inflammatory, irrelevant or off-topic messages in an online community, such as an online discussion forum or chat room, with the intention of provoking other users into an emotional response[1] or to generally disrupt normal on-topic discussion

I would have to 100% disaree my dad is a diesel tech at a Ford Dealership and he says that by this point in the 6.0's life cycle he had seen way more engine replacments, and major and minor problem in the 6.0 than he has ever seen in the 6.4. He said that the 6.4 so far is proving to be a good engine.
