Hey, Bill, don't beat up on yourself about it. If we
haven't done that particular dumb thing, we have certainly done others
{:>).
I have no personal experience. I have read that
silicon is suppose to be bad for the O2 sensor. I don't know if the
damaging effect is simply coating of the zircon material in the O2 sensor or if
there is some chemical reaction that forever alters and damages the
sensor. I presume you have verified that the sensor is still connected
electrically. More than once, I have found myself assuming that one action
on my part cause a problem and zeroed in on it - only to find that after much
wasted time - it was another cause.
So just to rule it out, I would check the continuity
between my O2 sensor and the indicator you are using.
I guess I would be tempted to take it out and soak it in
gasoline or something that acts as a solvent. I mean nothing to lose doing
that and perhaps it could clean the stuff off.

So, it appears that I am the only one dumb enough to
do this..:>)
Does anyone have any helpful thoughts? I would
hate to replace the O2 sensor and just contaminate the
replacement.
Thanks,

I just removed my exhaust to have some welding done on
it. When I replaced it, I added some anti-seize compound on the two EGT
thermocouples and also the O2 sensor boss.
When I started the engine, the O2 sensor worked for a
few minutes, then stopped working. I assume that it did not like the
anti-seize compound???
My question is…will it come back after a while?
If I need to replace the O2 sensor, should I try and remove all the compound
from the thermocouples as well? (they are ahead of the O2 sensor) Should
I run the engine for a while after I remove the compound to try and burn it
out of the pipe or should I clean out the pipe?
How bad is my situation? What to do….What to
do???
Thanks for the help!
