DIY EGR Tube Extension - Brazing

[99gtlimited]

So I was waiting for a while to figure out a good way to lengthen my EGR tube so I can install my phenolic IM spacers, and eventually I decided upon brazing using an oxy/acetylene flame, bronze brazing rod, and flux.

First I cut a spare EGR tube I had laying around in half.

Next, I found a piece of steel tubing that was slightly larger, to make a sleeve, and cut a piece roughly 1 cm longer than necessary.

Since the IM spacers are only 8mm thick, plus 2 IM gaskets, I have decided to lengthen the tube by approximately 10mm.

Here's a picture of the final product, after sanding. You can see a bronze strip where the steel pieces meet.


I decided to coat the entire thing with DEI silicone spray since I had some extra laying around. It is intended for use on exhaust pipes and should help slow/stop any corrosion/rust.

thanks! old school no doubt, but it got the job done. always fun to play with an oxygas torch, brazing rod, and an old can of flux

What about using "soft" copper tubing as an EGR tube? Just cutting the nuts off, sliding copper through and flaring the ends?

I had no problem re-bending my pipe by hand for phenolic spacers,
but it does help if the engine is out.

Old thread I know...but good work with that brazed in extension. I have 2 on hand right now so I'm going to try torching and stretching first and go from there.
