Help! How to remove stripped o2 sensor
repair kits with an oversize tap.
One of my Mufflex tubes is kind of sloppy in the sensor
bung, can only take maybe 20 lb-ft before starting
to yield. I used some stainless 1/16" welding rod to
"safety wire" it, twisting for tension, and it's held up
where it used to blow out at WOT.
You could also just grind out the old and buy a
replacement bung (or, if you're feeling all shade-tree,
cut off the upper end of an 18mm "anti-fouling"
spark plug adaptor from the HELP! rack at any auto
parts store. But this will be mild steel, not stainless)
and weld it in. I used to use the adaptor-ends for
putting sensors into stock iron manifolds on my vehicles.
