EGR valve
Could anyone tell me where or what EGR valve is being replaced, due to excessive regens. I don't have any error codes, and my tail pipe is clean as well, but my problem is I regen about every 40 to 50 miles. I purchased the truck with 36K miles, its a 2008 Job 1 F-350 SRW. I have had it into to to get the latest flash as well. When I got the truck I could average about 15mph highway. It now has 63k and I get about 11 mph on the highway. It has progressivly gotten worse the more miles I put on the truck. I hear people talking that the EGR was replaced due to it being stuck open and letting more exhaust sut in than normal. I'm sure the drop in mileage is due to the fact the regen is happening about 6 times a tank. I got to where I never worried about the regens just let it do it's thing, but everytime I drive the truck its smoking white smoke everywhere. It actually where I had to by-pass the grocery store on the way home due to embarrassment because all the smoke my truck was doing. I couldn't see the parking lot after I passed by it.

It seems to me if you're only doing 15mph on the highway then you should just give it more throttle?? All kidding aside be happy they are replacing the EGR valve and hopefully it fixes your problem. The new EGR valves are much better than the original and no longer have coolant running through them. Let them do what they are doing and see how it goes, it could very well lead to the poor MPG you are experiencing.

So do I and went in to my local dealer and asked if they would switch it out to possibly save some major headache and they said NO CHANCE. Understandably Ford will not pay for the repair unless it's needed even though a $500 repair now could save a $20,000 repair down the road.

Funny y'all should bring this up. I've got nearly two hundred miles on the new EGR valve and housing and am loving it. My truck hasn't run this well in a long while now that I look back on it.
The EGR valve we're talking about is the one on your diesel engine. It is front and center on the top of the engine.
Talk about funny.
How can something they are doing now lead to the poor MPG one's been experiencing?

Valve resides just in before the eng shroud on the motor. As you are looking at the motor it is just left of center. Right on top. It is a easy change.
I am still on the old style but mine works perfectly...but only 46K on the truck.

What? I thought the EGR was on the back side ?!
So those little EGR block off plates would be easy as pie to throw in then......
one of these days if it warms up, i'll be looking around under my hood.

I suppose I just worded my question all wrong when speaking of the EGR valve. My truck is not in the shop and Ford is not replacing the EGR valve, however I was wondering where the EGR valve was since reading here on the forum this was the cause of several issues due to excessive regens. Do you guys think this is really my problem from the issues I have been having. Excessive regens? I'm sure I have the original one in as the oasis report doesn't read of one being replaced. I was thinking of replacing it myself, but from the comment above kind of scared me. It doesn't seem like an easy task. What do you guys think, should I try and replace the EGR valve due to the problems, or should I look else where because of this issue?

If your engine has less than 100,000 miles on it and the EGR can be verified to be bad it is a warranty issue. On the other hand, if you take it to the dealer and they cannot verify it to be bad, it'll likely cost you for diagnostics.
My truck certainly runs well since the EGR replacement. Mt dealer did not stop with replacing the EGR, but replaced the EGR manifold as well. But then I think my dealer is one of the cream of the crop . . . and I'll name them here: Dick Edwards Ford in Manhattan, Kansas. They have dedicated diesel mechanic who really knows his stuff. This is one reason I bought the truck in the Little Apple.

Cheesit, if you're asking me, I don't know. I guess if the truck ran right without it I would put the vertical cooler in the attic of my shop with the many other parts I have laying around up there. That way I would have it if needed for the next owner when I sell, or to reinstall for whatever reason. I sure wouldn't get rid of it as long as I had the truck.
