lookin for one, and if someone has one, let me know....

[hotrodsbygeorge]

I have one.....all I have to do is make it :rolleyes:

LFP also has them :tu:

[L8 APEX]

LFP is selling them now, they are closer the cheaper for local folks. They also have the manifold cap I think..

I believe it affects your gas mileage just a little bit as well.

[Mark #2]

Okay, one description, there are many, if you search on EGR delete.
http://www.autoshop101.com/forms/h61.pdf

But generally the good things of the EGR are lower combustion temperatures, prevention of detonation, and gas mileage.

The EGR doesn't work at WOT, so there is no HP gain, the downsides are greater than advantages. IMHO.

PCV delete is also bad, oil contamination, just to name one.

Taking these things off of a daily driver is just stupid.:tex

[L8 APEX]

I don't like putting burnt gunk back through my engines. I have cleaned a lot of nasty arse inter coolers full of EGR deposits. I have also pulled engines down after doing the delete and they were much cleaner from the intercooler to the piston.
I asked Dennis Wells what he thought of EGR's. He said he would never recirculate exhaust gas in any of his high performance engines. Feeding your engine exhaust is a dirty dirty thing to do. It has it's purpose but I chose to have a clean engine not a gunky one.

It keeps the inter cooler and intake ports/valves a lot cleaner.
It makes plug changes much faster and easier to do especially on a hot engine.
It eliminates a bunch of clutter and vacuum lines from the engine bay.
It gives the truck a much cleaner and muscle car type engine look. All you see is blower and fuel rails, valve covers with the EGR stuff out of the way.

[Mark #2]

I will respectively disagree for a daily driver.

Why are you "pulling engines down after doing the delete and they were much cleaner from the intercooler to the piston"?

Higher combustion temperatures and detonation?

A race car/truck no argument, no need, you are never at part throttle when the EGR is working.

My intercooler has been very clean with the EGR connected for the past 8 years, a PCV filter is what it takes to keep it clean. IMHO

No hating, just my opinion, everyone has one.;)

[L8 APEX]

Engines have been running a hundred years before the EGR valve came along. EGR's don't make your engine last any longer. How can burning filthy soot make anything last longer?
We go into engines for many reasons mostly to change combos, configurations and general inspections.
I have no concern what the daily drivers do. I hope most of them leave emissions equipment in tact, EGR, PCV, catalysts etc. All of it makes the world a cleaner place.

My posts here are on the side of high performance. Not ONE performance engine builder in the country will recommend you run an EGR system. The ones I have asked laughed at me saying no way would they put that crap into their $$$$ engines:rll:.

From all the Lightning engines I has been into which is quite a few. The EGR is 90% of the black nasty coating on the inter cooler and intake runners. I have pulled the blowers off several engines with EGR deletes that still suck oil. The inter coolers are clean, the oil passes through the does not deposit the crusty black goo that comes from the EGR.

[Mark #2]

"My posts here are on the side of high performance"

The EGR doesn't have any effect on performance/HP at WOT as it is turned off.

But if you want to take all the EGR and PCV stuff off your DD, good luck.
Someone around here knows how to install a new motor.

[L8 APEX]

It is for the overall health and cleanliness of the engine. Appearance, faster plug changes and blower swaps etc. I am done repeating myself.
When driving around with the ERG cokes your engine with yuck it DOES affect performance.

We have done engine changes on several older engines and the EGR ports and intakes were restricted like cholesterol blocking an artery. In my 95 Tahoe it was completely sealed with hard black crystaline tar gunk.

[RSVT]

i got wat i needed and now is this easy for install, i done everthing else myself and have had no problem with anything , now for the instruction for install:rolleyes:

where can i get the manifold cap at....they dont sell it at LFP

[L8 APEX]

NAPA or Home Depot a 3/4 hose thread cap.
Yum, gotta love EGR crud can I have more please..
http://www.svtgalleries.net/gallery/data/500/medium/15nasty_IC.jpg
Half cleaned.

This is a seasoned cooler with the EGR deleted. It eats oil like all L's do this one even ate pieces of a blower. Nice and clean.

Trouble is that 90% of the trucks here are daily drivers. Or at least street trucks.

It amuses me to see people re engineering stuff.

[Sonicblue03]

So for a street truck the only benefit of doing the egr delete is appearance? What exactly can it hurt on a vehicle? If it keeps the engine cleaner wouldn't this be better for the truck? My goal is to make my truck a weekend street racer and occasional strip truck. I am confused now...:confused:

There are different opinions on this issue and you wont get a definitive, everyone agrees, opinion.. Terry feels that it craps up the inside of your engine, Mark feels it isnt worth the change. I dont think anyone would argue that if you can remove a bunch of stuff, it cleans up the engine bay, but then again, you have to reprogram the ECU to ignore the code that will get thrown when you remove it.. so you have to decide if you think its worth it to you..

[tiffo60]

I think just the time it saves you on the spark plug changes justifies the change:bows

[L8 APEX]

The EGR system was implemented in the late 70's to improve air quality for people. It was not engineered to improve engine life. Your engine stays much cleaner inside without EGR gasses flowing through it.
A simple analogy for the non technical:
An EGR valve is to an engine / as cigarettes are to your lungs. It fills it with a nasty black tar residue that eventually kills it/you.:evil
It is the KISS method or bringing the engine back to the basics of compression, fuel and spark.

Thanks Terry! :tu: I was hoping someone could put it into terms I can relate to...:tex

wiki knows everything


n a typical automotive spark-ignited (http://en.wikipedia.org/wiki/Spark_Ignition_Engine) (SI) engine, 5 to 15 percent of the exhaust gas is routed back to the intake as EGR (thus comprising 5 to 15 percent of the mixture entering the cylinders). The maximum quantity is limited by the requirement of the mixture to sustain a contiguous flame front during the combustion event; excessive EGR in an SI engine can cause misfires and partial burns. Although EGR does measurably slow combustion, this can largely be compensated for by advancing spark timing. The impact of EGR on engine efficiency largely depends on the specific engine design, and sometimes leads to a compromise between efficiency and NOx emissions. A properly operating EGR can theoretically increase the efficiency of gasoline engines via several mechanisms:
Reduced throttling losses. The addition of inert exhaust gas into the intake system means that for a given power output, the throttle plate must be opened further, resulting in increased inlet manifold pressure and reduced throttling losses.
Reduced heat rejection. Lowered peak combustion temperatures not only reduces NOx formation, it also reduces the loss of thermal energy to combustion chamber surfaces, leaving more available for conversion to mechanical work during the expansion stroke.
Reduced chemical dissociation. The lower peak temperatures result in more of the released energy remaining as sensible energy near TDC, rather than being bound up (early in the expansion stroke) in the dissociation of combustion products. This effect is relatively minor compared to the first two. It also decreases the efficiency of gasoline engines via at least one more mechanism:

Reduced specific heat ratio. A lean intake charge has a higher specific heat ratio than an EGR mixture. A reduction of specific heat ratio reduces the amount of energy that can be extracted by the piston. EGR is typically not employed at high loads because it would reduce peak power output. This is because it reduces the intake charge density. EGR is also omitted at idle (low-speed, zero load) because it would cause unstable combustion, resulting in rough idle.



Early (1970s) EGR systems were relatively unsophisticated, utilizing manifold vacuum as the only input to an on/off EGR valve; reduced performance and/or drivability were common side effects. Slightly later (mid 1970s to carbureted 1980s) systems included a coolant temperature sensor which didn't enable the EGR system until the engine had achieved normal operating temperature (presumably off the choke (http://en.wikipedia.org/wiki/Choke) and therefore less likely to block the EGR passages with carbon buildups, and a lot less likely to stall due to a cold engine). Many added systems like "EGR timers" to disable EGR for a few seconds after a full-throttle acceleration. Vacuum reservoirs and "vacuum amplifiers" were sometimes used, adding to the maze of vacuum hoses under the hood. All vacuum-operated systems, especially the EGR due to vacuum lines necessarily in close proximity to the hot exhaust manifold, were highly prone to vacuum leaks (http://en.wikipedia.org/w/index.php?title=Vacuum_leak&action=edit&redlink=1) caused by cracked hoses; a condition which plagued early 1970s EGR-equipped cars with bizarre reliability problems (stalling when warm, stalling when cold, stalling or misfiring under partial throttle, etc.). Hoses in these vehicles should be checked by passing an unlit blowtorch over them: when the engine speeds up, the vacuum leak has been found.
Modern systems utilizing electronic engine control computers (http://en.wikipedia.org/wiki/Engine_control_unit), multiple control inputs, and servo-driven EGR valves typically improve performance/efficiency with no impact on drivability.
In the past, a meaningful fraction of car owners disconnected their EGR systems[citation needed (http://en.wikipedia.org/wiki/Wikipedia:Citation_needed)]. Some still do either because they believe EGR reduces power output, causes a build-up in the intake manifold in diesel engines, or believe that the environmental impact of EGR outweighs the NOx emission reductions[citation needed (http://en.wikipedia.org/wiki/Wikipedia:Citation_needed)]. Disconnecting an EGR system is usually as simple as unplugging an electrically operated valve or inserting a ball bearing (http://en.wikipedia.org/wiki/Ball_bearing) into the vacuum line in a vacuum-operated EGR valve. In most modern engines, disabling the EGR system will cause the computer to display a check engine light (http://en.wikipedia.org/wiki/Check_engine_light). In almost all cases, a disabled EGR system will cause the car to fail an emissions test (http://en.wikipedia.org/w/index.php?title=Emissions_test&action=edit&redlink=1), and may cause the EGR passages in the cylinder head and intake manifold to become blocked with carbon deposits, necessitating extensive engine disassembly for cleaning.

[L8 APEX]

You internet mechanics need to leave motor stuff to the real mechanics. Ford modular heads don't have EGR passages to clog up. So your generic WiKi does not apply to this specific engine. Modular Fords run CLEANER without EGR's. I give up you refuse to accept my knowledge on this subject.

[Mark #2]

Just one more reference, ASE mechanic.

"It is important to remember this somewhat obscure fact: EGR systems are not only emission controls; they are also a means of lowering peak combustion temperatures to protect the engine from pre-ignition or detonation when using today's fuels. Thus, if you "defeat" the EGR system, you can also seriously decrease engine performance and life."

I am done on this topic.:beer:
I pretend to be a "real" mechanic.

[L8 APEX]

You said the EGR is not operational at full throttle. Are you saying every one blowing engines is doing it at part throttle with EGR's disabled? I doubt anyone has damaged an engine while cruising with their EGR off. Most engines I have replaced had operational EGR's. They blew at WOT in cold air in over drive. All of my fuel injected street bikes and ATV's have no EGR systems. I guarantee they will run forever with no problems part throttle, full throttle whatever. What about all the engines for marine and non emissions purposes that never seen an EGR? Are they in danger of damage? EGR's are on la very small portion of the world's engines. The EGR is not the savior and life giver of the combustion engine as you proclaim. Does that make any sense ?

Its not a savior

BUT the Engine System was designed with the EGR in place.
By people that know a heck of a lot more about it than me ... And you...

[99bolt]

Look at the 6.0 diesel. The Egr was put on it to appease the environmentalist and EPA. It does nothing but cause trouble for the motor.

[L8 APEX]

Yeah the EGR system has ruined all reliability diesels ever had. The EGR diesels are a nightmare. It clogs, it romps, it boils over, the coolers rupture etc...

Doug, I guarantee the folks that designed would tell you they it did it for cleaner air and to meet strict govt guidelines. Not for the longevity or benefit of the engine. The environment benefits not the engine. It is strictly and emissions control as labeled. An EGR system is essentially a tiny exhaust pipe running back into your engine, yum.

[hotrodsbygeorge]

A few thoughts on the EGR ...I worked on Cadillacs in the 80's and 90's and they constantly plugged up the egr ports in the intake so the soot deal is true.They even came out with carbon cutter valves because they had carbon buidup on the valves causing them to stick. ( not sure if that was totaly because of the egr ) When your PCM comands the EGR on it also changes the fuel mixture on most cars to compensate for the egr being on so deleting the egr would cause you to need to reprogram the pcm. My opinion is on a steet car/truck keep it . Any serious engine get rid of it because you dont want to do anything to " dillute the fuel mixture" If you notice most race cars have a pan evac. or a vacuum pump of some type to get rid of the blowby ( and to help the rings seal ) A egr valve is like putting blowby back into your engine.
Anyway just my thoughts on the subject :)

Wow 3 pages for someone asking where to get a EGR delete plate- board is kind of slow these days I guess

[slick-svt]

:popcorn

Did you cap off all of the vac lines??

[RSVT]

how many blks lines are removed from this.....

[03LightningRocks]

Holy Sh!t!!!!! 2 pages for an EGR delete wanted? This must be a new record.

[L8 APEX]

and get rid of the brackets and sensors you don't use anymore.

[RSVT]

and get rid of the brackets and sensors you don't use anymore.

the sensor i keep is the one at the rear of the blower right, and again is there two blk lines that needed to removed and cap or only one:confused:
