Hey all. Had my first 6.4l major repair this week. The truck had 551 km on it. The customer had it 2 days. It was a no start due to only being able to pump up too 2000 psi. I had the cab off 2 times. I first replaced high pressure pump as per pinpoint tests ME . Then pulled the cab off again when that did not work to pull fuel return plugs out of the back of the heads. Had to grind down 2 6mm allen keys, did the first one too much. Turned out to be # 7 injector leaking to return very badly. Had to mess with 3 cab cage nuts even being really careful after reading how bad they were. Here are some pictures. Sorry I did not have the camera with me when I was doing anything internal.
