Hi Bill,

I'm pretty sure I used the copper anti-seize compound on my O2 sensor.
I lost two of them in the first two hours of flight because the wire
broke off.  It was unsupported for several inches and I think it was
vibrating.  I don't think the anti-seize will hurt anything as long as
you don't get it on the sensor itself.

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!

 

Bill B
