losing the egr stuff

[Yellowsplash]

You can use a rubber freeze plug to block the port in the intake plenum. I believe the size you need is around 1 1/16. It has a bolt in the middle to squish the rubber to size.

The exhaust size is trickier if you want to do away with the tube...With my headers I stuck a bolt that was about the same size and welded around the head. I'm not sure how hard it would be with cast manifold.

And yes, the egr valve itself has a vacuum line running to it.

 

[disciplerocks]

Yes there is one vacuum line from the DPFE to the actuator that opens the diaphragm.

Any one want to post some pics of the 4.0 setup? I can probably get it bypassed for you.

What part of hot gas that is mostly already combusted getting reintroduced in your intake doesn't hurt performance? Egr is for one and one thing only. Emissions.

I am not sure how it is setup on my 2.9 or your 4.0 for that matter. I haven't ventured that far yet, but on my Focus you can just loop the vacuum hose on the DPFE sensor that tells the egr to open and it won't ever tell it to and won't throw a code.

It doesn't hurt performance because of WHEN the system is working, part throttle.

Yanno... I'm quite surprised this thread is still open. Now, correct me if I'm wrong... but isn't it illegal to tamper with emission control devices? Personally, if the vehicle came with it, it should still be there and operational. Not just a matter of legality... but responsibility for the environment. People wonder why they keep closing down trails... well this is one of many reasons that come to mind "increased emissions"!
Myself, I would like the privilege to go out in the wilderness to still be there for me in say twenty years. Governments world wide are just looking for an excuse to keep us "regulated" in what we do and where we go. Lets all start doing our part and start doing the ecologically "responsible" thing so that in twenty years, the "privilege" will still be there for us.

Lol I don't think they close trails because of emissions, but I've been wrong before. And if you live in a state that checks it then don't mess with it, but if not and you want to get rid of it then do so. Its the same as saying you can't turbo that or swap out the engine because it didn't come that way.

Case in point... all two cycle power products are banned from some US parks (can't remember what ones in particular). Reason... excessive emissions. And what about these "incentives" to reduce the number of older vehicles on the road... emission related. They have also eliminated the use of "aviation fuel" for use in off road racing in some states. What does this mean to us... the the eco friendly watch dogs are looking at what we (we being the guys that modify and enjoy the use of our vehicles) do and how we do it.
Now, I'm not saying we all have to trade our trucks off for a hybrid one and I'm also not saying mine is the cleanest burning one out there. But, I do know that whatever I put in my tank is being burnt off in such a manner that I'm not dumping fuel out my tail pipe. Hell, if someone asked me to submit to a smog or sniffer test I would happily oblige them (I have willingly submitted myself to emission testing and passed with flying colors). Also, at the risk of opening another ball of yarn, I do wish that the province I live in would mandate some form of emission testing on a regular basis.
Time is coming where the pastime we all enjoy, be it wheeling... racing... snowmobiling... dirt biking (choose your poison in the recreation world and insert it here) will be scrutinized for it's environmental impact and judged. It's up to us as aficionados of our chosen recreational sport to take measures into our own hands and "leave nothing but footprints"... and not carbon footprints either.

To give an idea of what's already happening -
I have a California Air Resources Board compliant 4 cycle weed whacker with a ventless fuel system and electronic ignition...(Thats what the manual said, electronic ignition). I'm not sure how the timing works in the thing. Interesting thing is it puts off no smell whatsoever when its stored, even with a full tank of gas. No two cycle stink to it when its running, and you can't see the exhaust at all.

4 cycle ATVs are already out there, and there are rumors of 4 cycle snowmobiles coming out. Even more nasty rumors of going to catalytic convertors on these small off-road engines.

It's not a rumor... it's a fact. 2010 Honda TRX 420 does in fact run a Cat in "CANADIAN" form... And we don't even enforce the CARB laws.

To go along with the emissions line look at the difference in the outboard motors now. I can remember when you fired up the old outboard and an oil streak immediately appeared at the back of the motor! Now you don't see any traces unless there is a problem. Off hand I would say it for a lot more & safer fishing,boating,whatever.

The ebst way to plug open holes on exhaust is to go buy a can of readywhip. The aerosol kind. Take the blue or brown cap and fill it with JB weld and stick it over top of the hole. Takes no time, dries fast and you can grind it down for appearnces. I did this for my long tube headers on my mustang and it worked like a charm. the heat had no effect and it never broke loose. It expands and shrinks at the same rate as the header steel.

I apologize. I stand corrected.

Does that apply to fuel economy too? Or would that take a hit (or maybe increase?) if my truck was egr-less?

There should ne NO change in economy. Since it takes X amount of hp to move the vehicle with egr working, it stands to reason it takes the SAME amount of hp without egr.
HP= fuel

x2
me too
remove egr valve and tube connecting exhaust
I think that we make laugh of us with this thing

y cant i find my egr valve? the book says for a 94 4.0 its rightby the iac on the intake, but i cant find it anywhere. theres no holes or anything where its suppose to be.
