I don't have a 6.4, so this isn't first hand, but from things I've read.

6.4's use the back 2 cylinders to regenerate the DPF, so the back 2 cylinders get very hot every time. The problems this causes is that the back 2 cylinders experience a lot of wear, and this causes the bore to wear away completely removing the cross hatch on the bore. The cylinder heads also crack, and it's getting harder and harder to find replacements. There are only 4 head bolts per cylinder, so head gaskets often leak, allowing coolant to enter the cylinder.

Go to powerstrokehelp.com and you will see a lot of videos and information about all the Ford diesels.

If you're thinking about buying a 6.4 you probably want to talk yourself out of it.

I found a much better explanation of why you shouldn't buy a 6.4L Ford.
