I did not do it yet. I am hoping to do it this weekend. The tube has a crack right at the lip of the tube that sits against the supercharger. I am going to use epoxy on the crack and also make a gasket to help seal. I will let you know hopefully Monday how things worked out.

If your egr tube has a crack it will cause a very rough idle due to vacuum leak. Spraying the tube with carburetor cleaner while the engine is running will cause the idle to smooth out if you have a leak. They soapy water will show you wher the leak is. I tried high temp silicone sealant but it only helped for a few days. I took the tube to a shop to have it brazed but they were concerned that they would burn a bigger hole. I finally decided to try brazing it myself. I had never welded anything before but I was able to pull it off. So it is possible but I would reccomend finding a shop that can do it as there is the riks of fire, and serious injury. Also, I have found several egr tubes at the junkyard but they have all had micro cracks so far.

Do you think soldering it would work. It is only a fine crack.

I tried both liquid and regular solder and neither held. Those exhaust temps are just too high.

Thanks for letting me know that. I am going to see if my dad can braze it for me.

I brazed the crack in the tube but I am still sucking air at the top. I did cut a gasket for around the top of the pipe but when I tightened it down the bracket that holds the tube was crooked so i removed the gasket. I am going to try again tomorrow and make a gasket the size of the whole bracket to see if that seats better when I tighten it.
Also replaced the MAF sensor today and know the car idles high (1500-2000rpm) and then drops to about 800 and almost stalls. It goes back and forth like this. If I spray carb cleaner at the top of the egr tube when the idle drops to around 800 then it idles up and sounds ok. This tube is a real hassle.

Been there, done that and as you now know it does not work that way.The tube should fit snug against the bracket like a collar. I cut my gasket to fit the bracket. I used the bracket as a guide for the outside diameter. Then I cut a hole for the tube and one for the bolt. Slip the gasket over the bolt and line it up with the hole in the SC.. (I think one side had adhesive to assist in positioning) Insert the egr tube and slip the bracket over the stud. Attach the bolt and tighten it down.
