Guys, have a friend with a 2005 6.0 L like mine. He recently got stuck with the huge bill from the local dealer for a new EGR valve replacement. It only worked for about 2 months. They replaced it again. Then when he went in again for some reason they didnt want to stand behind it. The mechanic unplugged it and told him to forget it. Qestion for you experts. What does this do or not do? He tells me that he is getting better mileage and it runs much better. Supposedly the Ford mechanic told him that it would not harm the engine. There are no idiot lights or nothing.

 

The ford tech is an idiot. Unplugging the EGR can cause the fan to not operate properly not to mention the fact that a dealership disabling emission control equipment is a HUGE federal crime. The new EGR should be covered 12/12 minimum IIRC. Sounds like they just don't want to stand behind their repair.

 

When was the truck first bought? How many miles on it? What state? It is possible the original work should have been covered under warranty. The emissions warranty in California, Maine, Massachusetts, New York and Vermont are all 7 yrs (from purchase date) and 70k miles. The rest are 5 yrs and 100k miles.

As Tim said, the shop's advice is bad. If the friend wants to delete the EGR system, it can be done, but it should be done properly.

My opinion is if EGR valves are failing or plugging up, there is a root cause somewhere else and it needs to be found.

 

I have my egr unpluged and there are no issues from it.

 

The mech is also saving the dealership money by not truely fixing the truck...

 

My EGR valve kept failing because the EGR cooler was leaking. They probably just don't want to deal with the EGR cooler replacement.

 

I have had mine unplugged for 5 years, no problems ever.

 

you really belive this.. the tech is costing the dealer money. You have no idea how the system works.
the shop gets paid by the manufacture, the shop then takes the profit and pays the tech. no work done means no money in anyones hands.
Please explain to me your logic...
Now back on topic.. the issue is more then likly a coked intake or egr cooler lettng carbon blow into and holding the valve open. It should be fixed.
If its just a case of a bad valev that fails performance testing then its should be service part warranty and covered.
leaving the fan disconnected and running VXCF9 can lead to fan operation issues. I have not tested this with other calibration levels. there is a rather long thread on the matter.
Now all you have to do is figure out whos right.

 

Well guys,,,, some say yes and some say no. Isn't amazing? Mine? it is still plugged in. I have replaced it once. I have 140K Juice edge (which according to this forum is not good) I have the magnaflow exhuast trubo back. Very few other problems so far. But according to all I am told is just a matter of time. I love my truck. But have a cautious love for the engine. My friend swares that his truck now proforms better and so far absolutely no problems. Better fuel mileage etc. I don't know. I think I will join the class action lawsuit concerning this engine and the loss of resale value. I dunno!

 

You have a Ford Tech offering you his expertise - on his own dime. You would be well advised to seriously consider what he has to offer.

Discussions on law suits are against Forum rules - besides, it is ridiculous to hear you talk about it after you chose to significantly modify the engine (both the degree of mods and the choice of tuners). Take responsibility for your choices ...........

 

Well said Mark!

 

matty and I both found this out very close to the same time. read the whole thread rather interesting.

 

Gentlemen, accept my apology for violating the rule. Will not discuss that again. As for the advice. I do not know who is what on here. Have read a number of post. One thing that seems obvious is there are many experts with opposing opinions. As for my Highly modified engine?? If what i have done is highly modified then I have missed something. I do have the juice edge. it has never been programed above 2 for towing a fifth wheel and 1 for economy. I do not hotrod my truck. You speak of the Ford Expert! I dont know who he is. But as for Ford Dearlers????? You can get as many opinions as there are ford dealers. I have found that the High volume dealer who sell fleet sales are much more equiped to tell you what will hurt the engine and what will not. As for my two local dealers??
I am meticulous in my maintenence schedule. This is my 4th Ford diesel. 3 7.3's and now this 6.0. Before that one Dodge, and two chevy's. Volkswagen and Toyota. All diesel. I am addicted to them. So..... before you start telling me to listen, just understand. I in no way am a hard headed nor am I unwilling to listen on this. And I am fully aware that I do not know it all. Cheers.... and I will fall back into the world of silent lurking and reading.

he was refering to me. I work and have pretty much spent most of my 18 or so years working at fleet heavy dealers.

 

Just look at the sigs. Most of the techs will let you know in their sig.
