egr pipe repacement

[ncsdaonex]

can i use a piece of copper pipe for the egr pipe and flange the end and connect it with compression fittings if needed?

i have a 1990 ranger 2wd 2.3 4 cylinder 5 speed

no. the egr tube isnt just an empty tube. is has a metered orifice inside that has to be exactly right or else your EGR system will recieve too much or not enough flow.

On my 92 Ranger, my EGR tube is just a empty tube made up of 1/2" or 3/4" mild steel. A 88 Tubo coupe tube is made up of mild steel also. There is a small hole coming out of the exhaust manifold that may meter exhaust gas flow but the tube is just a tube.

You can use copper pipe for a EGR tube just use the Type L pipe as it is thicker then Type M. I personally would just get a new one from Ford (if they are still available) or have your local hydraulic shop bend you a new one. Most shops charge $25-35 to make a new one. Just take in your old one and you should have a new one in a day.

of the two smaller hard lines coming from the EGR tube, one should be on the "exhaust" side of the oriface, and one should be on the "EGR" side of the oriface. this is how a DPFE system works. IIRC, both of those small tubes come off of the EGR tube itself, so the meter oriface would have to be placed inside the EGR tube, between those two smaller tubes. if the metered oriface is at the junction of the EGR tube and the manifold, than one of those hard lines would have to be attached to the manifold itself (this may be the case...i just seem to remember both lines coming from the EGR tube itself).

On my 2.3 there is only one tube that goes from the exhaust manifold to the EGR valve and it is just a hollow tube. I know this because I hacked one to pieces to make a new one for my turbo motor.

im talking about the two smaller tubes leading from the EGR tube to the DPFE sensor.

When I had to replace mine it ran me about $60..

There is only one tube. What engine are you talking about? He is asking about a 1990 2.3

I believe this is what Sludge was talking about. If not, correct me.

Mine looks like Joseph's post. It's actually rattling under higher rpm accelleration. Is it bad inside?

Not sure what you mean by it being bad inside, but thats the noise mine was making, but it sounded more like the entire exhaust was falling off

What the problem ended up being was the end of the Pipe that connects to the manifold rusted out completely and was just dangling there. The hard part of replacing the pit was getting the fitting off the piece of rusted pipe that was still connected to the manifold. The dealer ship said to make sure not to break the fitting because they are hard to come by for some reason

What I mean is, "is there something inside that can come loose and rattle because that's exactly where the sound is coming from"?

I changed out my valve cover gasket a while ago and messed with that pipe and the noise went completely away. Now it's back. It's been a few years though and this is a completely different engine. And tranny! I'm thinking of removing it over the weekend to get a better look.

Thanks.

Theres nothing inside the pipe itself if thats what you mean? Maybe remove it and do a little cleaning around the rivets of the nuts with some steel wool and tighten it back on there.

that is what i was talking about...though thats obviously a 3.0, all engines will have the same connections (that 2.3 diagram is innacurate).

between those two tubes is where the oriface is located.

The 2.3 diagram is correct for the year that the original poster was asking about. 1992 and down 2.3's DO NOT have addtional pipes or a oriface in the tube. It is just a tube. I have enclosed a picture of mine so you can see. One of the EGR tube on the ground and one of the EGR tube on the truck.
