Come to think about it, when I "accidently" cured my B&K troubles during the muffler replacement I removed my O2 sensor just to make sure it had not "welded" itself in place. I didnt replace the sensor; just removed it, cleaned the threads, smeared a thin coat of anti-seize and put it back in. It was quite a job loosening the sensor so it might be that it was not grounded before removal but was grounded after.

It's quite possible that the antiseize poisoned your sensor and ruined it. I did it to one of Jon Casey's a month ago by being thoughtless -- the sensors come with a dab of "safe" antiseize already applied to the threads. This was a reinstall and I don't know what/where to get stuff that's safe -- it may even be that they simply are very careful where it's applied, though I doubt it. Anyway, Jon's lasted about five or maybe ten minutes before it was toast. I doubt that it would interfere with the connection though, if the sensor were tightened reasonably. david David Beierl - Providence, RI http://pws.prserv.net/synergy/Vanagon/ '84 Westy "Dutiful Passage" '85 GL "Poor Relation" |
