I recently moved, and found myself in need of a truck that would not only be a daily driver, but may also be called upon to tow a decent load from time-to-time. So I did what any right thinking individual would do, and bought myself a 2003 F250 with a 6.0 Powerstroke.
It's a 2WD King Ranch in incredibly clean shape, with just over 170,000mi. Built in January of 2003. Runs well, but not great at low RPM. I've put a ScanGaugeII on it, and coolant and oil temps look really good. It came with good service records, and appears to have belonged to and old guy who kept up with basic maintenance. I'm not trying to run a crazy tune or make huge power. I just want to have something that's good to drive, and is reliable with basic maintenance.
Issue #1: EGR delete. Getting rid of it makes perfect sense to me. I contacted a local shop that is reputed to be the local Powerstroke specialist (in TX, where there are no emissions testing) regarding doing the EGR delete and they told me that, in their experience, the 6.0 is more likely to blow head gaskets after a delete because the EGR acts as a blowoff for the turbo, and once removed will create pressures that will lift the heads off. I've never heard of this. Their recommendation is to perform a cleaning with some products from BG, to the tune of $850. This sounds like a ripoff to me, but I'd like to hear from ya'll about experiences after doing an EGR delete...is blowing the heads off a legitimate concern, or am I being fed a load of BS?
Issue#2: Low boost: This thing is a turd below about 3,000 RPM. Beyond that, it runs like a madman. I'm averaging about 16.9 MPG. It could be the solenoid, or the VGT sensor or tube, or the turbo itself. Or a leak. I have a new set of pipes and boots for the turbo, and will start there. If anyone has any further insights on low boost, I'm all ears!
Beyond these immediate issues, I've picked up a blue spring kit, and a 4" exhaust kit from MBRP. Oil changed with Rotella T6 and Archoil friction modifier. Been running the Archoil fuel additive as well. The biggest problem I've run into thus far is that the secondary fuel filter cap appears to have been installed by Magilla Gorrila about 5 years ago. I've banged on it with a hammer and chisel to the point that it now has a hole in it, and is undrivable. That's a job for tomorrow.
Anyway, thanks for having me, and I'm looking forward to any advice I can get. It's a nice old truck, and I'd like to drive it for years to come.
