Well, Rock Auto had a special on the O2 sensor for my '92 Sentra
w/1.6L gas engine, so I said, "Why not? 177K it probably would
not hurt."

    Except I cannot remove the old sensor. I've been spraying it
with Liquid Wrench for about two weeks, and I went to remove it
yesterday. No dice. I have a 7/8" O2 socket, but it doesn't get a
good "grip". The corners are starting to round over on the sensor.

    The replacement sensor is almost spark-plug like, but the old
one's flats are not as high, and it sits in another little plug
(like a reducer bushing, which I presume is welded to the
manifold) and there is not much room to get any kind of tool on it.

    I can live without the new sensor; I just don't want to break
the old one and not be able to replace it.

    Any hints or tips?

Put a jubilee clip round the socket to stop it splaying open.

.... Jubilee clip? I'm not sure what that is. If it's similar to
a stainless steel hose clamp, I tried that already. But I don't
think the socket is splaying open, I think it's riding up over
the corners of the flats.

    Thank you, and correct me if I have misunderstood you.

Sorry yes Jubilee = brand name of British hose clip, used generically
just like Hoover.

All the O2 sensor sockets I've seen are full hex with one side cut out
for the wire. If it rides over the corners then a 12 point will too.

There are very few justifications for 12 point sockets. If you are
using a socket, you are using a ratchet 95% of the time, so the extra
points do nothing but give you less grip. For the few times you use a
breaker bar, 6 points are the way to go and the 12 point is definitely
useless.

The only exceptions are times when you really need a breaker bar and
you just can't do the angle with a 6pt; or for 12 point bolts (there
are some used on a few cars).

TO the OP - if an oxy sensor socket won't do it, you can buy 6 pt deep
impact wrench sockets and do it that way. You'll need to sacrifice the
wires.
