What are the draw backs of EGR delete?
 

Hi

I recently bought an 03 F-350 Fx4 Powerstroke 6.0, 186k miles. From what I can tell so far it's completely stock. I've heard some gripes about the 6.0 but they all seem to be revolved around mods. From what I've gathered, if left stock the don't seem to have many problems. Nevertheless, I would like to delete/bypass/remove the EGR system. But I have some questions. I've heard removing this component will avoid the problem of overheating the heads and stretching the head bolts causing head gasket problems. I've also heard it can give me more horsepower, and up to 2 mpg increase in fuel economy. My question is, are there any drawbacks or downsides to this? Will it cause any minor problems I need to be aware of? Other than the legal issues....to whom it may concern I do NOT plan to operate this vehicle on any public roads... That being said, I'm concerned about what mechanical effects this will have.

Thanks
:tu:

Glad u asked that I have had a few people tell me the same thing after I did my egr delete

Technically it is illegal to operate it on the road after an egr delete.

From what I have learned from this site the benefits out weigh the negatives. It is the EGR cooler that causes most of the problems with the 6.0 PSD. That in combination with the oil cooler.

There is s ton of info on here about the deletes. Do a search and you will be amazed what has been posted on the topic

Yes, I'm aware of the laws, hence my disclaimer...lol :-)

I've read a lot of the threads on this topic and I'm confused about a few things. I haven't seen a clear distinction in the kits as to whether it removes the EGR system all together, or just removes/replaces the EGR cooler. I've come to understand that the cooler gets easily clogged causing it to fail, thus not cooling the exhaust fumes entering the intake. It also is known to boil the coolant, which I really don't want. I'd just assume remove the EGR system all together as long as it doesn't cause any major mechanical problems or have a negative effect on my fuel economy.

The delete is just that - it deletes the cooler. Companies also make upgraded coolers.

Try this link - they have good info. I am no way a sales person or advocate for this company - they just supply good info. When I get funds and decide to do something I will most likey do a cooler upgrade not a delete.

Not a damn thing, if you dont get smogged do it.

[QUOTE=bkmac;860340]The delete is just that - it deletes the cooler. Companies also make upgraded coolers.

See, that's part of my confusion. Does it just delete the cooler, not the entire EGR system? If there are exhaust fumes recirculating into the air intake it has to be cooled, so I definitely don't want to delete the cooler and leave everything else. I want to remove the EGR system all together, meaning I do not want ANY exhaust fumes being recirculated.

And in this case, why do I need a kit for anything? Why can't I just remove the system all together?? lol

I think you get the picture. The FACT is that you can find whatever point of view you are looking for on ANY site. Now these may be accurate, or as wrong as two boys kissing, your responsibility is to sort through the garbage and come to your own conclusions. If you read enough Bomber posts, you'll see that I have talked out my I LIKE TURTLES once or twice. :c:

The only drawback is you keep alot of money out of the repair shops hands. before you do the delete do a good coolant flush, I think there is a sticky on it, after flushing do the delete of EGR cooler, Do a rebuild on oil cooler/replaces the part that gets clogged/ and add a coolant filter... You won't have to worry about having any major issues with the truck being otherwise stock..

The exhaust is taken from the up-pipes, routed through the EGR cooler, into the intake manifold. The EGR valve is what allows or restricts the flow of exhaust into the intake manifold. Once the cooler is gone, the exhaust can not get to the intake manifold.

You can do a full delete (removes the cooler itself, and replaces the stock up-pipe with the EGR cooler opening with a solid up-pipe, and you can either leave the EGR valve in or remove it, whichever)

Or you can do a "block off" by welding freeze plugs in both ends of the EGR cooler, that way it looks like everything is in tact for emissions testing (visual test) but no exhaust flows through anywhere...

Or do the upgraded cooler like that from BPD (what I would do if I lived in Cali).

There are a few different options out there from the $1 freeze plug method to the $600 GoGo manifold that actually removes material from the intake manifold so that coolant is never even routed through the intake manifold to begin with.

MBUB707. What happens if you don't tune and turn off the egr?

EGR= Exhaust Gas Recirculation

How does the exhaust enter the intake manifold?? Thru the passenger side up-pipe.

Most EGR delete kits will block off the pipe at the EGR cooler or delete the cooler. When the EGR cooler is deleted they usually give you a straight up-pipe replacement. The EGR valve does nothing more than meter the flow of the exhaust as it exits the EGR cooler. With tuning the EGR valve is rendered useless so you can leave it in place (visual inspections) or remove it to use the plate.

Without using tuning most will see a EGR code or CEL that reflects the lack of EGR flow.

You will get a CEL on the late04 and up trucks, the 03 and early 04 trucks don't throw a code.

also the 03 and early 04 /before 9-22-03, don't have the nasty scoop in the up pipe like the later trucks do so the uppipe can be capped off at the connection of the egr cooler and still have no restrictin, on the later trucks they replace the uppipe to remove the restriction.

Heavy Assault Says: Without using tuning most will see a EGR code or CEL that reflects the lack of EGR flow.

My question is, Will that make the truck run rough?:argh:

For your 2004 it has been my experience that will not happen. Long term running could lead to issues so don't wait too long to see the results.

it will run fine, even if a code is thrown they are just soft codes to let you know something isn't right. it won't put it into a "safe" mode or anything. I ran for 200k with the egr valve just unplugged and never had an issue.

the only reason i removed my egr with a sinister delete kit was i blew a head gasket and warped headers and it backed up oil into my coolant so i replaced all of them and did the oil cooler and water pump while i was down there and replaced coolant chamber but back to the question i feel the only thing that changed in my truck was it runs a little bit hotter than before and i use just a little more coolant in the truck not substantial but i can def tell theres more than before. on my SCT tuner when im watching it was at temp of 189 degrees now im running at 200-210 i was told that was from delete kit.

I live in CA and I know I can't do an EGR delete without throwing a soft code stipulating I had to do more driving to have the on board monitoring system finish the tests. It has been some time since I did it but if I remember right it was code P1000. I put a OBDII scan gauge on it and it showed the EGR monitor wasn't being satisfied. It never did clear until I put everything back to stock and it cleared within a few miles of driving. It would have never passed smog since they won't even attempt until the OBDII system doesn't throw any codes. Stuck with stock as long as I live here.

with the 03 truck you can unplug the egr valve and leave it till you have to get smog checked again and then plug the valve back in a day or 2 before the test.

big bofman so you mean...
 

so i live in cal too. I just replaced my second egr in 60K miles. I want to go with the delete and leave the egr in for visual inspection. My 04 f350 has an engine manufactured in 03, i can see the sticker on the engine. So you think i can pass the obdII portion if i plug the egr back in a couple of days prior to smog check? no soft codes? sorry i meant bobfbigman :) JR
