Egr, Hmmmmmm!!!!!!
I find this interesting and confusing !!
I took my truck to the dealer to have the new flash put in. Which they did, but thet also said that they put in a new EGR.
The thing that baffles me is , I have around 33 thousand miles on my truck,
but for about 28 thousand miles or so, I have had my EGR unpluged.
I cant help but to find this odd.
How can a unplugged EGR go bad? And if its unplugged what difference does it make anyway?
Am I missing somthing here?
I like to think Im a logical person, but Im having problems applying logic here.
Unless it was bad before I unplugged it.
Any thoughts??
Thanks for your time
Jeff

If it is an '03 as your profile indicates it could be blow-by / residue that is still collecting around the valve or gate. On inspection it could look pretty bad. Plus, you probably coded for the EGR valve.
In addition, it is a universally recognized problem with the 6.0 and many techs may change them out as they would their underware....a matter of customer good will so to speak.

This isn't the old day's where parts were actually inspected to determine if they are good or bad. Now if the computer say's it's, it's bad. Could be that saftman is right and the EGR was replaced under the recall. Or it could be that having your EGR unplugged threw codes and the tech threw a part back at it.

They also replaced my EGR when I had the latest recall done on my 04. I really hadn't noticed until a couple of tanks after the recall when I went to make sure "The Wart" was disabled. I had mine unplugged since the last time it was replaced about 12K miles prior. I cleared all codes and plugged my "Wart" back in before heading in for the latest and greatest.
I think the others who have responded are correct. Ford may jsut be putting a new EGR in for all who do the "voluntary recall" because it'll be back for an EGR sooner or later.

The general concensus here seems to be the same.
Replace it, good or bad.
I guess I have a different mnd set, if its not broke dont fix it.
From what I am understanding it is still a good idea to unplug the EGR ?
Thanks for your time

Simply unplugging the EGR valve isn't good enough. There is enough back pressure in the exhaust to push the valve open. It doesn't take much effort to pull the valve open or another way to explain it is there isn't much spring pressure holding it closed. If you have EGT gauges you will really notice the difference after the valve is permenatly sealed, especially after several visual inspections.

Jeff- Here's the EGR Disconnect thread. I put it on the page that Jerricho describes the way he sealed his EGR. The whole threads an interesting read, but a little (52 pages) long. Enjoy.

I ran my 05 with the EGR unplugged for a while and it almost completely eliminated the turbo lag. However, after a few hundred miles I noticed that, even though the turbo spun up faster initially, it would not build total boost as high. And the famous turbo whisle was replaced by a low drone. So, I plugged it back in and after a few miles it's back like it was. Big turbo lag but turbo boost is improved and turbo whistle is back. Anybody know the technical explanation for all this?
