Hi I have an 94 gt wondering if the egr tube is supposed to come apart where the corrugated part ends or is the tube supposed to be totally solid? Thanks in advance
I already know and understand that I replaced the egr valve and position sensor was wondering if the tube was designed to come apart at the corrugated part of the tube I'm assuming not.It unscrews from the header and on the other end it unscrews from the egr valve.

Even if the pipe is designed to where the smaller diameter pipe,at the bottom,fits inside of the corrugated section,the pipe doesnt have any play in it.In otherwords,if you were to try pulling the bottom piece of pipe upwards so it would go back inside of the corrugated section,it would pull right back out again as soon as you tighten the bottom nut up again.It would still have to be JB Welded,etc to close it up again.Mine comes apart at the bottom side of the corrugated tube it sits on top of it and there's a smaller diameter tube in the middle.

The only way you might possibly be able to push the smaller pipe back up inside of the corrugated section would be to buy a double sided fitting,female threaded on the exhaust manifold side & male threaded on the egr pipe side.You would screw this fitting onto the exhaust manifold then mount the egr pipe to the fitting.The inch or so height of this fitting would force the smaller pipe upwards so it would go up inside of the corrugated section that inch or so.Hopefully my description wasnt confusing.Basically right now,because of the pipe being seperated,the bottom part of the pipe is too short to fit up inside of the corrugated section,so adding a fitting between the manifold & egr pipe should give you an inch or so of additional height which will force the smaller pipe upwards by that inch or so.
I agree,I'd replace it too (like I stated in post #9)vs trying to repair it.I still have the original (stock headers) and it's a B to screw it on to the valve. If it were to break I'd buy a new one vs trying fix it.

However if he's dead set on trying to repair it,the fix I mentioned is one way to do it.
I dont know why Ford had to change the design so that you'd have to use a pipe setup like.Well I know why,so they can sell you a replacement pipe to make more money.Ive always hated any egr system thats connected to the manifold by a thin piece of pipe.The Ranger Ive got uses a thin pipe setup too connected to the manifold & its got a 4" long crack running down the center of it.Those pipes just dont hold up to that kind of heat.
On the pipes with the corrugated section,they tend to break when you start loosening the big nut because the pipe tries to rotate too when you break the nut loose.I dont know if it would help to spray some penetrating oil between the pipe & the backside of the nut or not,that way when you start turning the nut the pipe will hopefully not be stuck to the nut.Oh well.
Will soft copper hold up to the heat thats created by the exhaust gases, and more importantly,the direct/indirect heat coming off the exhaust manifold itself?? I know it'll hold up to hot coolant,etc,but have you tested it on your ride before?? Im not doubting it,Im just curious.... Thanks WB...you need to get a new one or fabricate one out of soft copper from like home depot or whatever
