Looking at a 2008 F250 6.4l

[rowekmr]

I am looking at a 2008 F250 King Ranch with 90k miles that is stock and will get a 3 year bumper to bumper Ford warranty. I know these engines had issues with front covers, valvetrain, and making oil (anything else?). I was only going to keep it a few years that I need it under warranty so any issues would be fixed wouldn't cost me more than the deductible. Many say these have to be deleted for durability reasons but because of the warranty I can't do that. How well (or bad) do these run stock if it's driven regularly, the maintenance is kept up, fuel kept clean and proper (Ford) parts are used?

I tried to search for past threads but nothing comes up with I enter 6.4l or 6.4 in the search box.

Thanks

Maybe manufacturing stopped, but trucks rolling off the line with em didn't due to using up inventory I'm sure. Fact is there's many more 6.0 than 6.4. And bottom line is they both suck unless modifications are made from the highly unreliable stock form.
That's the facts!

Exactly right.

I can speak on the 6.0 Had Two of them and 6.4 still have it. The two 6.0's were **** period!!! the 6.4 after being deleted and tuned has been a towing machine. before the 6.4 was tuned it had all the same regen **** making oil which is actually just diesel in the oil and smoking probs. after the delete at 40K miles and for the next 70K miles not another problem with the engine and I tow alot and heavy. I can tell you that I have friends with 7.3's 6.0's and 6.4's and the 6.0 is the worst of the 10 or so that I know personally. To the OP I would still pass on the 6.4 it is still not a 7.3 and never will be. My neighbor has a 2001 7.3 with 600K and never even had an injector replaced. Good luck. Will

^Wrong on the years.
6.0 was 03-07 in the suoerdutys and the 6.4 was 08-10 but 08 was a late release so more like 2.5 years.

I think the baddest sounding. Diesel pickup is an uncorked 6liter! Sounds like it's gonna inhale you and spit you out!

Bottom line no arguing is even viable on this point. If either engine was worth a chit, they would have not completely changed engine design or mfg after 4 years and 3 years respectively.
That said, there are some crazy power 6 and 6.4 trucks. AND if I was a mechanically inclined kid and wanted a bad @ss HD diesel pickup on an budget, I'd be buying a 6.0 every time! Bulletproof it and have arguable the best chassis and a cool sounding tough truck.
If I wanted down the road gas n go reliability and power, neither of em would make my list!

The 6.4 was a huge step above the 6.0 in terms of reliability and issues. The biggest issue with the 6.4 is poor fuel mileage stock. If it were me, and you live an area without emissions testing, I'd save the money on the warranty for a delete package. You'll get better fuel mileage than current diesels and really it's a reliable engine and tranny combo deleted. As long as you are reasonable with your tune, get a custom SCT programmer and tune.

If you keep it stock you'll get in the 14-15 mpg area unloaded. You could get a newer gas engine for the same price and similar mileage.

It's a hard decision. The 6.4 is a way better engine than people give it credit for once you delete everything. But resale isn't the best when you sell it.

Negative ghost rider!
The 6.4 was par with the 6.tow at best.
More emissions which gave them fits, terrible fuel economy, more costly to work on, still must remove the cab for major repairs, fuel pump issues, etc. Hardly an improvement. Probably why the 6.4 was only in production for barely 3 yrs vs the 6.tows just over 5.

That's why I said If you delete the emissions. If not, you get terrible mileage and Ford did a terrible job with emissions.

The 6.0 was from 2003-2006. The 6.4 was from 2007-2010, same number of years. The 6.4 was stopped because of new emissions required for 2011. Ford decided to stop using international and build an in house engine for the 2011 year as they lost their butt in warranty claims and reputation from the 6.0 and 6.4.

I owned my 6.0 and I actually miss the way it drives when I programmed it, it drives better than current Duramax that if deleted and tuned. My 6.0 has so many other problems I had to get rid of it. I know many people that own 6.0/6.4 and both are great engines once you take care of them.

Point is, if you want a diesel on the cheap, and you know what you are getting into, the 6.4 is a good engine. If you don't want to mess with it, spend the money on a Duramax or Cummins.

The 6.0L was 2003-2007 in the F Series and was available in the E Series until the 2010 model year so it had a considerably longer run than the 6.4L. Even with deletes the 6.4L has a bunch of other inherent design problems that would steer me well away from one.

X2. Most Ford techs say they would rather have a 6.0L than a 6.4L which really says something. We have a couple of 6.4L trucks at work and they have been terrible with tons of emissions problems and constantly making tons of oil.

One of the big knocks on the 6.4 is the fuel system gets contaminated with water and there goes 5-10k to fix it. Check the fuel water separator, if it's full of water don't assume they always checked it with every oil change. Also add an after market F/W seperater and better indicator. Ford still has a very bad rap for their engines. Go Cummins or the LBZ duramax

Fish does not recommend any dpf equipped diesel without def including the first gen 6.7 cummins which was known to have problems.

I concur with that statement!

LOL...

Ironically there's a guy a work who has a 09 6.4PSD that is pushing 300k miles. The only thing repaired on the engine was a idler pulley and the transmission bit the bullet at ~250k miles with the factory transmission oil still in it which reflects the overall maintenance performed on this truck. :E

The truck is driven mostly highway miles in which the first gen emissions can tolerate, but throw in a lot of city driving/idling and that's when the problems really happen.
