Feedback on 2003 Bulletproof'd Ex
Hi all, looking for a bit of feedback. I had a 2002 Ex with the 7.3 that I sold about 2 years ago and miss it, looking for another one! I found a 2003 with the 6.0 that's been bulletproof'd but the current owner says it needs injectors. First off, what's a bill like that run from a diesel shop? And is it worth it? Owner says truck will start but he won't run it long b/c he doesn't want to burn up the motor, but could there be other damage that's been done if the injectors were failing a while back? He's replaced two already so seems to know what the failing injectors sounds like and sounds like he stopped driving it once that started, but thought I'd ask all you out here for your opinions.
TIA!

injectors failing? could be he has a bad FICM, bulletproofed? by who? just because the studs were done doesn't mean they were done right. I'd take a stock engine with a new oil cooler and egr that runs good and has good temp deltas over a "bullet proofed" rig that had studs installed by some hack

First thought at what the guy told you: run away.
Second thought(s):
1. I don't think bad injectors would "burn up" a motor. Maybe if they're dumping fuel into the cylinder? When my injectors were getting weak, I had hard starts even in warm weather and some smoke on start for a bit. That was with at least 2 injectors failing.
2. "Bulletproofed" is a varying thing to different people. If it's just studs, then I wouldn't call that bulletproofed. Generally, that means an EGR delete, studs, oil cooler, stand pipes, dummy plugs, the list can go on. It's not as simple as studs.
Seems to me that there are probably a ton of them out there that you could look at aside form this one. If it's SUPER cheap, then maybe not an issue to grab it and do the work. These days, I don't know what a full rundown would look like, but injectors themselves are sort of expensive. Warren has a rebuilt set for ~$1K. Changing them out isn't necessarily a hard job, but could be time consuming. And while you're in there, you'd want to do other stuff as well.
Check out the 6.0 forum here and take a look at the tech folder. If the guy is local and you can scrounge a laptop and get Forscan and an ELM adapter, you can check all these things yourself and tell what's actually going on.
Good luck!

Thanks guys, I was leaning the same way anyhow. When I asked more about the bulletproofing he said it was done before he'd bought it and he has no paperwork and no specific idea what had been done. As for the injectors, I have no idea what's really going on, he said he could start it but didn't want to run it too long for fear of damaging it too badly.
In all honesty I'd much prefer to have another Ex with the 7.3 like I had before, but it seems those are hard to come by in my area for the time being. I'm not in any major hurry so I'll be shelving this 2003 and keeping my eyes open.
Thanks again!

actually they get a bad rap. there is nothing inherently wrong with the 6.0. deal with the basic issues EGR, oil coorler, and it is fine motor. Mine is at 138K and runs like a top. gets 19 on the highway easy.
I have severl friends with the 6.0 excursion, none of them had had issues.
