Ive heard the average guy paying 16-1800.00 for a new DPF...Is the cat in place? Is the K & N a filter or a complete intake? The complet intake would have to be put back to stock at the same time everything else is..or you will get codes...

You should want the truck back to stock and insist on a warranty...or walk away. It not the same if you did the mods..but since you didn't..you're kind of blind going into this and if you rely on a XYZ to be upfront....yikes..they're ingnorant with most vehicles outside of their line up and the average salesman doesn't know JACK..he only knows sales.

You don't want someone else's head ache.. I would not buy a truck that was tuned or modified...right there you're taking a chance..Might run good for a month or two and all of a sudden..you need majr motor work or a new motor..$$$$$$$$$$$$..I could not afford a 18k dollar repair..so when I'm 1 year away from my warranty expiring..I'm gonna sell my truck...as much as I love her...she's gone.

 

let's not forget the other inspections as well.

cooling system
fuel system
oil
filters

 

when you say egrs are deleted do you mean because most tuners shut off the operation of the egr and most likely it would be stuck and non operational?

 

The truck looks clean in the pictures...The Degas bottle looks pretty dark in the photo..need to check that out. And it looks like a mod. air intake as well

 

does that coolant level look low enough worry about?

 

Th coolant looks to be just above the T fitting which is on the lower end of the two lines on the bottle which is about right..I have mine at the upper line...but the color looks dark..could be just the photo..but I can see my coolant through the bottle and it looks orange ish in color

 

The EGR's have been removed from the engine. If its put back to stock, the engine will go into limp mode and be rendered useless.

If you really want the truck, you can buy the truck as is, buy a tuner, take it to Ford, have them reprogram the PCM, then you'll have to put the new tuner on immediately. Problem: anything goes wrong with the truck, dealer may not be able to diagnose because of mods and you don't have OE equipment to reinstall.

 

i am slightly confused, how do you know the egr's have been removed from the engine?

 

I saw the photo on your link to the listing. No EGR and the intake elbow has been changed out to a high flow elbow along with sensors being removed.

 

THANKS RM2738! I did not even notice that the EGR had been removed. from what i have read about EGR on the 6.4 as long as they are shut off that they don't cause problems correct? or do they need to be removed like this one? any idea what sensors would be unhooked and if that would cause problems or has to be done when one removes the EGR. I have been on the fence on buying this truck, i like that it has been dpf deleted but know i would have to return it to stock before i add a new programer at the tune of ~$1200. at the same time i have another truck in mind that has the programmer and delete that i like from a private party so he knows what is on the truck, but it has 133k miles.

 

Even if the Egr function is turned off thru tuning, there is still a small amout of flow thru the egr valve, i have yet to see one that shuts off 100 percent. An EGR system shut down like this does not protect you from a EGR cooler failure that could cause the engine to hydraulic or cause other damage to the engine. The only way to prevent any issue is to completely remove the EGR system which would be the best if you have no warranty and are not concearned with federal emmission compliance. Second to that would be to install block-off plates.

The only alternative to those would be using aftermarket egr coolers like the one from bullet proof diesel if you wanted to keep the Egr system in tack and reliable . The Egr coolers on these truck are not good quality and just a matter of time before they fail.

If you return the truck to stock with the egr valve and components disconnected i can guarantee the truck will go into limp mode and u will have issues. You could easily spend 4500.00 just putting the emission stuff back on this truck.

IMO i would be Leary buying a truck with these mods from a party i did not know. The owner could have done this for more reliability or the owner could have been power Hungary and abused the truck leaving the next owner with a hornets nest, but thats just my opinion. Its not that there bad mods to have had done, u just don't know how the truck was treated and wat issues could be underlining at this point.

 

Even though the EGR may be turned off, there is still a possibility of leaks in the EGR coolers. They also are a cause for higher EGT's. Removal is ideal. No real problems caused by them being removed. Again, if it were me, I'd want to purchase a vehicle with all the OEM equipment. Not necessary to have it installed if you're just going to delete it again, but if you're ever going to sell it, you'll be better off returning it to stock. Also, as I've mentioned already, any significant failures, the ability to return to stock will allow Ford techs to troubleshoot easier as they're not having to work around something they aren't familiar with.

 

looking at the engine bay picture i can see the egr is missing also you can usually see the vertical egr cooler right? so that looks to be missing also correct

 

Yes. That's what I was referring to when I stated the EGR's were deleted.

 

Take the advice that's been given and walk away from this truck. Unless they are basically giving it to you and you have extra cash to spend on possible break downs. These trucks are NOT cheap to work on or fix and there are WAY too many variables on this one.
