What happened to it?
They brought it in for coolant loss. I added 3 gallons of coolant. No external leaks. I checked the oil and it was halfway up the stick (way overfull). I got an approval to change the oil (military ambulance). I drained out 10 gallons. After refilling, it had a very audible rod knock.

Hopefully they still have the removable doghouse on them still... Still not a whole lot of fun.

I've seen lots of 6.0 work, but no 6.4... im slightly excited to see pictures cause i have a feeling there even more of a pain to work on than the 6.0's...

Finally started on it. Partial cab lift (because of the ambulance package). Gonna come out the front. I'm trying to come out and go back in in one piece.

Update.........This one came back with a p0003 (volume control valve circuit low). Diagnostics led to the high pressure fuel pump cover gasket shorting out (requiring cab lift). The 6.4 originally had this problem at first release, but they redesigned the gasket with convolute on the wires. This one was too short on convolute.
