03 6.0 after truck gets up to operateing temp (175-195) it wil just die and its making a fart sound under hood replaced ipr valve which was a pain and icp ( only cuz I broke it ) ipr valve was 358 dollars running out of money only add ons is 4" Mbrp exhaust and k&n cold air kit no chip or tunner at this time on truck any ideas or advice would be great.

 

Why did you replace the IPR valve? No need to spend money on parts that aren't broke. Someone else just said this recently and it rings true with these 6.0's. Test, Verify, Repair!

Need some more info on the truck like how many miles, service intervals, oil used, last time fuel and oil filters were replaced.

Usually when they quit only running hot, it's a high pressure oil leak somewhere.

 

I change oil every 5k I use motorcraft 10-40w and change fuel filters every other oil change there is 120k on truck I replaced ipr because I was told by the local shop that once hot the valve was failing and droping oil pressure from injectors and the truck has no codes no cel light nothin

Just took truck to local shop they said got low compression on #1 and 7 cylinder with my luck it's a head gasket going to check copper washer on injectors any other ideas would be helpfull

 

Failing FICM's can throw injector codes. Easy as pie to test with a buddy. 5 minutes worth and that includes drinking a frosty beer. At 120k it's hard to tell, could be injectors, but not a definite. When the truck is running, how is it? Still drive like normal? Did shop just hook up a diagnostic tool or actually do a compression test?

 

Got anther problem just found engine has alot of blow by so much it will blow cap off oil fill tube if it's just sitting on there

Just Diagnostic tool only, truck runs great smooth until a little miss then will die always starts right up after about 10sec of cranking then idles rough for a few seconds then smooths out
