    Thank you, it looks like I have some other problems to attack now as I have some new engine codes after I repaired the ERG valve and replaced the fuel filters.

Hi there,

Well there must be some high pressure oil leak than some of the others guesses, normally a dummy plug in the high pressure oil rail, when engine reaches operating temp. the o-rings in the hight pressure oil system become more limber when hot and will not seal as well if they are torn, melted or have a problem. Or the problem was in the fuel filter the fuel heat sensor mounted on top of the filter assembly would leak it was hard to see but it leaked enough that truck would start and only run for minute or so and stall. Tapped to the hole and put a plug in and it remind the problem, also check the injectors as there plastic tops leak. 

Good Luck!!

Thanks

2006 f350 6.0 powerstroke diesel missing. help


there is no wastegate on a 6.0l turbo. its a variable geometry turbocharger and doesn't need it. i have never seen a turbocharger cause a misfire, the turbocharger is most likely not your problem. if you didn't clean the intake out when replacing the egr valve there is a really good chance that the egr is bad again. also, a bad egr cooler can cause repeat egr failure. also, fuel injector control module is a common cause for misfire

2006 f350 super duty diesel start good in the mornings but after is warm it wont start.


these trucks use a oil fired fuel injector, if your high pressure oil pump has eccessive wear or if your oil to broken down from being run to long between oil change, it will not build enough oil pressure to fire the injector once the oil is thinned out from being hot. An oil leak in your high pressure oil system can cause same problem.

I have a 2005 Ford F350 6.0 Diesel and It wont start after the motor gets warm. It also starts rough when cold. When it is running it runs great. Any help would be appreciated.


I had this same issue and luckily my F350 2006 was still under warranty. Basically there is a high pressure oil system that has a tendency to leak internally. You won't see any oil leak. When cold the oil has enough viscosity to keep the pressure sensor from not allowing the engine to start. When the engine is warm the system doesn't reach required pressure to allow the engine to start. In short it's a Ford dealer repair. Good luck.
