i'm helping my father find a new truck and he has always liked fords he's got a 02 7.3 now and he dosent want to go with a brand new truck because of price and wants to avoid the 6.0L so i was wondering what is everyones thoughts on the 6.4L i don't know the first thing about how good the 6.4L was son any help would be greatly apreciated thank you

 

6.4's are a pretty good improvment over the 6.0, I'd buy one if i was into ford

 

I haven't had any problems with my 6.4, B U T you have to do these simple things so, you won't have problems (1) You must drain the water from the fuel at least once a MONTH {it's easy, just turn the lever by the frame of the truck at the driver side (2)change the TWO fuel filters, by 15,000 miles (3) Because of the regen, change your oil, by 5,000 miles. You do these thing, & your 6.4 will last

 

thanks for the help i'm not sure what he is gona end up getting but great to get a little info on the 6.4

 

I would like to say that the later year 6.0s in my opinion arent really that bad.my neighbor has an 06' w/ 110xxx and no problems ever.im sure 6.4s are alright.my $0.02.

 

The 6.0 are OK if, You get an AFTERMARKET EGR, If you add a tuner, you must stud it or you will be blowing your head gasket

 

Ive seen any year of 6.0, 03-07, that lasted 100k miles with no problem. But then I have seen many that didn't. I think you're taking a gamble with the 6.0 no matter what year you buy.
