On my '83 RRC? :flipoff2:

I went to Home Depot and picked up some brass fittings that would hopefully adapt my O2 sensors into the larger bungs on the exhaust. They work (for now) but were about 1/16" too small on the outer diameter and while I was able to torque them pretty tight, I don't know if thread sealant will be the most optimal solution.

FWIW, the brash bushings were 3/8" x 1/4". I still need the 1/4" inner diameter threads, but I dunno if I can find it in a 7/16" OD.
If you can, buy me two :D

Oh, and the computer isn't throwing an O2 sensor code anymore. :D Smog check tomorrow will tell the story!

hydrocarbonss were 26 at idle, 25 at 2500 rpm (220 ppm allowable)
CO2 was 0.03 at idle and 0.30 at 2500 rpm (1.30 allowable)
can't remember the O2 levels, but they were pretty low as well.
The aged RRC is probably cleaner than my Disco :eek:
