Interesting point there, Oh Conical One. Say, have you or anyone else
seen the symptoms of a blown headgasket with ethylene glycol-based
antifreeze going out the pipe and contaminating the O2 sensor. It's
always referred to as one of the failure modes and especially something
to check following a head going pop, for diagnosticians, but I've never
heard/read a description of the actual detailed symtoms at the O2 end,
like does the output range collapse, shift, just get slow, what?

Only those having observed an O2 failure shortly after blowing a
head-gasket, need reply. (I hate the thot of having to search thru a
bunch of pundit theoreticals, ifyaknowadamean :).

I also hate the idea of having to sacrifice one (a sensor, I mean) just
for the learning experience. :)

Shannen I 'spect would be a likely one to have observed this from his
dealership experience, as well as any of the rest of you bloaks who are
especially keen/proficient at blowing head gaskets. :)
