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.

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.
