03 F250 6.0L, CC, SB, FX4, 4x4. 125,700 miles. I changed batteries two days ago cause they were DONE. FICM reads 47.9 koeo, 48.3 cranking, 3.4-4.7 running. i know its shot also. but my other concern is i changed out the fuel filters with Motorcraft last night and pulled out the EGR valve and it was DIRTY. i looked down in the hole and it was filled up with soot. not to the top but enough to worry me. cleaned up what i could. put everything together. started driving it back home from my shop and whenever i romped it i could hear a really high pitch whine. was about 1-2 seconds after the turbo was already spooling. got louder with rpm increase. but when i got home i had the wife come out and rev it and i climbed under the hood looking and listening and never heard it. only came on when it was driving down the road. any clues? i am completely lost right now with it. i would definitly appreciate any help i can get. this is my first diesel. i'm thinking about paying 2400 for a warranty and just sending her in for everything i find. especially with the rep. but if i can manage to do it myself without any problems then i want to stay away. its a 4 yr 75,000 mile and covers engine, transmission, drivetrain, electric, cooling, a/c, fuel and delivery, and some other stuff. i'm active duty Air Force and just don't quite have the big paycheck to constantly put parts in this thing.

truck is completely stock.

 

Make sure your turbo intake tubes are nice a tight and did you make sure the EGR valve seated back right??? Sorry you bought a 6 oh no..

 

yea i did everything i could to make sure it sat back in. but the turbo tubes is a good idea. i never thought about that.

 

The high pitch whine I'll almost guarantee is a cracked up-pipe... not terribly uncommon. I've had this before too. They crack in the bellows. Crummy design.

I can not believe your FICM is actually that low in voltage. Sending you a PM.

 

dont listen to the 6.0 haters, with some preventitive measures and comnon sense these are GREAT trucks

and our trucks look better than dodges anyways

 

If it a up pipe it will hiss when you start it up and with the hood up it will burn your eyes if you are up there looking around, most of the time,
At what boost does it wine? also these turbos in the 03 whisle a good bit, thats not is it?

 

. oh don't worry bud. i love my truck. just wanna get the kinks out of it. i got it to be a hauler and daily driver. i live in New Mexico for the Air Force and am from Michigan so i am using it to tow my mustang back home whenever i go for dragging and the family to see and appreciate. i can do everything to a gas motor but diesel is a different story.

i'm not sure what boost it is. sorry. i don't have anything to tell me. i can say around 2000 rpms and up though. never hissed when starting. just when romping in drive. park and revving heard nothing.

 

Mike is great with these trucks. He's helped me with alot of problems, and this site is great even if you dont have an issue. When you get the problems worked out, you should stick around

 

i defintily plan on it 03 powerstroke. i'm a big time car guy and enjoy helping people as much as i can. i'll be getting advice and trying to give it as much as i can. where i am with my problems i wanna be a good guy to help others without the experience or knowledge so that their not stuck broke down or paying outrageous shop fees.
