6.0 cuts off when it reaches operating temp
 

I have a 2004 f250 6.0 It has the 2003 motor in it. I installed new injectors and it started but is shutting off when oil reaches operating temps. If you let it cool down it will fire back up. Then i replaced the HPOP, IPR, and the high pressure oil lines. Still it continues. What could be the problem?

possibly the O-rings on top of the injectors, they actually sit in the oil rail that sits over the injecters, is your oil rail the "log type" or the pretzel type??

log

sound like the classic scenerio for the sct fitting on the 05s, your truck doesn't have that,almost sure it is a high pressure oil leak, runs good cold because oil is still thick, when oil thins out it leaks easier, the HPOP puts out thousands of PSI so leaks are not good.

did you replace the Orings in the oil log when you replaced the injectors,

Well, it ended up being an oring in the top end of one of the injectors. It was my fault guess it happened on the installation. Sending it out to RCD and they are fixing for free!

cool, glad you found it, good luck
