    1998 7.4 Vortec EGR tube replacement/repair

    Final update. Big thank you to TagAllen for the egr tube he had left over from one of his projects. The tube is an exact replacement and will be installed once I get a moment to do so.

    Well all, quick update. Looks like the possible “source” that I had located one from has been a waste of time. Since Oct7, the part was ordered and on its way to me leaving Bonanza Auto Dismantlers in Shingle Springs CA; Friday OCT 9....still waiting for its arrival. Called multiple times to...

    Any chance that you located the one you thought you had? Thanks

    Stainless commercial gas line for a water heater or furnace is similar yes. It can be purchased in the yellow coated (which will burn off due to that line not being “heat” rated like the stainless EGR tubing). Also, the JIC flare fittings are far smaller that the fittings on the Vortec 7.4...

    I will try and get a photo of the damage later but essentially the previous owners didn’t pay attention to the tube while tightening the JIC/ Flare nut and twisted the tube, which ripped a hole in it. In order for me to “clean up the mess” I had to cut a 3” section of the tubing out to get back...

    Did find two options on that site, but nothing within driving distance. But I did send emails to both yards inquiring if the tube was available.

    Fabbing that is... stupid autocorrect

    I agree fanning is seemingly going to be my only option, and finding a suitable material is going to be the next challenge

    I thought about that, but around here it would honestly be cheaper to “fab” something than have the reprogramming done I believe

    Yes, I did get that response from GM, and I agree, thus far find a used one has been virtually impossible for a “reasonable” price or that is useable. I think I am going to have to hunt for some materials and see if repair/ rebuilding may be possible.

    No, the one you found is for the small block Vortec engines.

    I appreciate the information. The tube itself has what appears to be flare or JIC fittings on the manifold and EGR. Removing the old one isn’t the problem, it’s finding a way to repair the hole/ missing section or find a complete replacement tube.

    Hello all, First time member looking for a lead or some advice here. I have a motorhome that has a 98 vortec 454 and I need advice on repairing a EGR tube from the the drivers manifold to the EGR. The tube has been twisted and now has a good sized hole blown through it. I cut the section out...
