I hate these things, seems I have an oil leek on a new to me tow truck and I think this is one of the culprits. Besides that reason I jsut want rid of it! Anyone know of a place I can get a kit that deletes this thing and keeps the SES light off?

NvrenufHP, you owe me a phone call! I need your help on a few others and lost your number:damnit

It wasn't me!;)
With some time, and a truck in front of me, I could probably make some sort of EGR delete, maybe work off a modified 6 litre(VT365) delete. There's always a way.
I'm not the 466E guy here, I'm the kooky hobbyist.

The EGR systems on the DTs are alomost bullet-proof as long as the coolant is kept above the MIN mark - as you are an OO, I'd guess that'll never be a problem.

There is no extra power less the EGR cooler and increased emissions, simply no reason to do it.

*Can* it be done? Anything is possible, H#LL the Egyptians built the Pyramids with hand tools and levers right?

I am looking at it from a UOA sample and oil longevity standpoint. Not looking for more power, just trying to eliminate the BS that can ruin the motor. MAybe I am just taking my small diesel ideas and worthlessly trying to apply it to my big engines.

I was talking about when we talked over on Tow411. We talked but we never got to finish because both of us got busy. Anyways, I owe you some reviews on the 04 466e, but first I shoudl do somethings more than just driving it! I just love driving it the way it is, ofcourse I could always use a little more power!

I doubt deleting the EGR would change UOA in any meaningful way. Keeping the oil cool, not ideling and using good quality oil would do FAR more from my experiences.

EGR actually keeps Combustion Temperatures and Pressures (CT/CP) lower because the fuel burns in a much more controlled fashon with EGR than without. You get a little lower peak CP but you get CP for a longer time. Notice that modern EGR equipped diesels make more power with the same displacement than the older ones could. They are more efficient at making power.

If you want to ruin your oil FAST, increase ICP to get more power! The HPOP is responsible for generating a LOT of heat in the oil and shearing it more quickly than with Common Rail systems. Anyone familiar with hydraulics knows that when you increase system pressures you also increase fluid temp, so increasing ICP actually shortens your oil's life.

One other thing, make SURE the "Clean Power and Ground" connections (B+ and B-) and fuses in your battery box are GOOD. I mean that the female terminals are tight on the males or you could be causing yourself a lot of trouble with low ECM power. One thing to look for is discolored terminals, especially on the fuse holders and if in doubt, go to the dealer and get a new "jumper harness" before you start wasting time troubleshooting "Unexpected reset fault" or "ECM voltage below threashold B+" faults.

So a 10K is a bad idea for the trucks oil?

Thanks for the tip, maybe thats the every once in a while check electrical system light on my 04?

No, that would affect the engine only. The Check Electrical System light is related to over/undercurrent on one of the lighting circuits, in an '04, most commonly the Low Beam headlamp circuit because of a bad (brown colored) connector shell under the hood on the cowl above the fuse/relay center.

Hey john!

Sorry to butt in.am familiar with the "brown connector"issues.do you know if you can purchase just the connector or do you have to purchase and replace the harness with all of the connectors?

The connector shell and male terminal for the "D" cavity (LB headlamps) is readily available from any (good) International dealer.

New problem with the 05. I have a hard to start issue that is related to the Intake Heater. Can you take a picture of one for me so I have an idea of what I need to look for in regards to the failure?

Look where the aluminum intake elbow is bolted to the manifold, there whould be one or two studs where the two pieces meet. None = no GH, 1 = one element GH and of course 2 studs = 2 element GH.

The GHs get their power thru one relay for each GH element and the relays are ECM controlled based on temp and altitude. The relays are fed from a fusible link on the starter B+ terminal.

We are now attempting to block the EGR and cooler. Just bought another 05 with EGR and it needs a little paint, while its waiting for the paint booth, it will become our design truck. I will let you know what happens with this, and if all goes well, we may start a little production of this and become a Supporting Vendor. That's if it works, HAHAHA.

Well my brother got a little eager and is now using my truck as a test truck since it is on the road daily with a base mileage.

Pre-delete: 6.4 MPG
Post-delete: 6.9 MPG

These are readings with only 500 miles since the delete, I will report more as I get more miles on this. Thus far we have only blocked at the EGR. Next week we intend to block the cooler at the manifold. That will reduce coolant temps and help the flow of exhaust. After that I will be in contact with TS Performance to see if there is a way to shut off the EGR fueling and timing maps in the ECM. Therefor bring more power and economy to the table.

I am hopefull this works, if so, it will look stock and boost economy and power. Something DT466 w/EGR owners have been looking for since these engines came out.

Couple that with the oil temp sensor trick, and you should gain some reasonable fuel economy.

No codes, at all. EGR only does a self test for position, nothing else.

Drove 315 miles on a tank for the first time ever! 7.3mpg, thats the highest since we have owned this truck and that is on B10 Bio-D. Cant wait to see how it performs on #2 or B2, anyways.

This was mixed driving with 110 miles being highway and the rest in city. Truck "feels" like it is a tad more on the peppy side. Still ironing out some bugs, but we should have the EGR cooler blocked at the manifold by the end of next week and will get another set of number after that.

I have a EOT sensor on order and should have it Monday. Once I install that I will also report any changes in regards to that mod.

you can order a manafold end for the front end of the exhaust manafold and use it on the #6 end to remove the cooler and plug your water ports with "freez out" plugs to compleatly remove it and have a clean looking job

Want to keep the truck looking OEM. Just incase a DOT gets a little to friendly with my truck and actually has a clue. There are a few of those in my neck of the woods.
