Buddy of mine in Calgary JUST bought an Expedition Max with a 5.4. Apparently it's got 486 000kms on it. I think his intent is to do a bit of overlanding with it? Just took it in for a lift and bigger tires.
Wow. 486k is impressive. I have plenty of hate for the 5.4 3V but I have seen some with big miles. The bottom ends are solid. If you keep up on the timing chains, guides, tensioners, cam phasers, oil pumps, roller rockers, plugs/coils, they do seem to run reliably for a long time.
