oxy sensor

[Mike Mulholland <meyeke@netinc.ca>]

welll..the quest to change the sensor went quite well today. :>) . using my
die grinder and 3" cutting disc i was able to decapitate my overly long
sensor, allowing access to the 22 mm hex base. of course i already have
removed my intercooler for reinforcement in anticipation of enjoying my new
chip power. i also had to remove the airbox and that was a challenge even
without the intercooler and air ducts. when decapitating the sensor it
became obvious that the centre section was a _very_ hard ceramic material
that was eating away my cutter faster that the ceramic was being eaten. i
cut around the perimeter of the metal cover of the sensor as far as i could
(100 deg or so) and then applied the box end of a 24 mm wrench over the
protruding stub and snapped the stub and its inside ceramic. a few back and
forth wiggles of the almost decapitated part and it was free in my hand.
from there i was able to use the deep 22 mm socket with a 5" extension and a
1/2" breaker bar to loosen and remove the sensor. i used anti seize _on the
threads only_ and installed and connected the new sensor. the old one was so
plugged with exhaust byproducts it has obviously not worked for years and
there is no mention of it ever having been changed in the p/o's records.
