2008 F350

All,

Been looking at diesels and ran across a '08 F350 4x4 with a 6.4 in it. I was looking at used diesels but more in the 1-3 year old range. Any issues/concerns with that year, age, etc.?

I really like the 6.7's but really don't know a ton about the 6.4's? I am planning on keeping whatever truck for quite a while mainly for towing hence the reason why I was looking for a "newer" used one?

Price seems about right at $29K compared to $45+ for others in '15-'16 range.

Thanks in advance for your candid feedback.

    My city public works trucks are both 2008 Fords with the 6.4. Both were purchased new and both have around 70k miles on them. Earlier this year the F550 developed a low power output issue and threw codes for a low fuel pressure problem. A friend of mine is a Ford mechanic and recommended I replace the fuel filters 2 times but bet it was an injector pump. I replaced the filter and it ran OK for a bit but did it again. We took it to a shop and they replaced the injector pump at the cost of $4,500.

    Sounds like the 6.4 is a bit shaky compared to the 6.7?


    What you just said is tantamount to saying: " Jeffrey Dahmer was a nice guy with a slight eating disorder." ;)

    From my friends that have 6.4's "The only reliable 6.4 is an EGR/DPF deleted 6.4".

    Even Fish doesn't recommend a 6.4. Now THAT is telling! :B

    Or as a Ford tech says: "the 6.0 is junk and the 6.4 is expensive junk!"

    May be of use to you. Do this BEFORE you buy.

    Edit: should've added "if you buy"

    I would not pay 9K of a 6.0 or 6.4. The fact that you are here asking questions about a 6.4 is very telling. Get on google and start reading.
