Here is what I learned from a International rep at the International truck tour(great event by the way) Well they had a cut away of a VT365(6.0) on display I started looking at it and he came over to see if I had any questions. First question was about the EGR..He said DO NOT disconnect the EGR.... The computer will try to compensate for the ERG causing poor turbo and engine performance. He started to get way over my head with the details of the EGR duties. So I'll take his word for it . INTERNATIONAL SAYS "DON'T DO IT". Here's the link to the tour www.internationaltrucktour.com

 

Disabling the EGR Valve has always been a personal choice.

Easy for the International and Fords reps to stay the course on the company line. They ain't driving 'em or fixing 'em in a hot shop . Repeatedly. (Notice I didn't say techs)

I wonder if the company rep can explain why for the last 16,000 miles I have had absolutely no issues and, in my case, performance was somewhat enhanced. I guess my computer compensated for it run good.

In addition, I wonder if the International rep can explain why people such as top1flight and many others, only resolution to engine problems has been to disable the EGR Valve? With immediate positive effect I might add.

Keep in mind that the 6.0 is the VT365 only in principle and basic design. Once Ford gets it, it becomes a 6.0 which in practice is not the same. What works for one does not necessarily work for the other. The software and performance enhancements make it a different engine.

Too bad the International reps don't make it out to see top1flight, tn_mac, jfralph, t_j82, and many others.

It disappoints me that a person that you trust to have the knowledge and skills you seek will make a statement like that. Better that he make no comment than to make a blanket statement such as that.

When they design the damn thing so it will not break trucks...then I will be happy to plug mine back in.

In the meantime, as I stated many, many times, it is a personal choice. Read, study, digest, evaluate, act.

One can only do what they feel is right for their truck.

Good thing the colonists didn't stay the course with the good King of England. Ding, danged outlaws.

 

I had a different experience with mine unplugged. EGT went up at par throttle cruisining and my max boost went up about 3-4psi.

 

Unplugged for 35,000 miles now and the truck still runs like a top. Still has turbo lag in the hottest part of the day but it had that before I unplugged the EGR but not as bad after. I just powerbrake a bit though and I am off like a shot.

 

I typed that wrong my max boost went down 3-4 psi.

Sorry guys.

 

Sorry folks but now I need some help...I have a 05 PSD and am thinking of at least trying to disconnect the EGR to see what happens. After reading the "thousands" of threads on the issue I don't know if I have a trottle body or not! Can someone help me?

You do not.

 

05 MY and up no longer have the throttle body; the new intake elbows bolts straight to the intake manifold.

 

I doubt this will be of much use to most people here, but I might as well throw it out there anyways.

If you want to physically remove the exhaust flow to the EGR cooler (which on top of the other benefits of disabling the EGR, keeps the coolant system MUCH cooler) it isn't very hard to do if you have an angle grinder and either a MIG welder or a TIG. You can probably get away with a stick, too. This works especially well on 05 MY and up trucks with the "scoop" in the uppipe assembly.

To start, here's a crappy camera phone picture of what it looks like when you are done. (see bottom of post) If you plan on doing it and need better illustrations to go by, just let me know.

The short uppipe assembly, which is removable from the rest of the assembly, is held on at the EGR cooler by a clamp, the top by 2 bolts (heat them up to remove them or they can shear off) and a 2 bolt flare flange at the bottom. Its a fairly small peice once removed; you can get it out from underneat the passenger side of the tranny bellhousing without too much trouble (its not too easy, either)

Once its out, the flange that bolts to the EGR cooler needs to be cut at the weld bead where it is held onto the short feed tube. Once it is cut and ground smooth, a flat peice of plating needs to be welded onto the cut portion to form a cap, and then ground to match the surrounding metal. There's not alot of clearance once it's bolted back up, so remove as much metal as possible without destroying the flange itself.

Once the flange is cut off, the short feed tube needs to be removed from the actual uppipe itself. A good cut with a cutout tool along the weld is all thats required, and then grind smooth. To cover the hole, a 2 inch peice of exhaust tubing (just cut out a section a little longer than the hole, about 160 degrees across the tubing) and weld in place after griding.

Bolt the cap onto the back of the of the cooler to keep crud from getting in the system, and reinstall the uppipe (I would recommend using new metal gaskets). Check to make sure the weld isn't leaking exhaust, and you are done. No more EGR flow, period, and there is a good 2 inch space preventing the exhaust heat from entering the cooling system.

 

I have an 05. Will it help or hurt to unplug the EGR? Most of my driving is unloaded. 75% city/25% highway.

Others are asking the same question about the 05. Way to many posts here to read, but didn't find a definite answer about the pluses and minuses on unplugging EGR on an 05

Thanks

 

The biggest '05 negative, IMO maybe the only one, is the CEL will illuminate. Some ignore it, some tape over it, some buy a new EGR Valve and use as a dummy.

The problem I have with the first two is if you leave the CEL illuminated you will not know if your truck is trying to warn you of some other event that is taking place.

Just some food for thought.

 

The dummy EGR won't work. There are other sensors involved which will throw the CEL on. Maybe we can all have a shop somewhere give us a discount on full engine/tranny replacement and we can buy a CAT in bulk so it's cheaper as a group...and get rid of this joke of a setup already.

 

Now dog...you don"t have to go and act like that...and on such a nice Sunday afternoon, too.

 

the instructions to disconect are in the tech folder and this is a very big thread at 539 posts.

 

mine does not illuminate
