[V8] Oxygen sensor

[Kneale Brownson]

You'll be really lucky if it amounts to "simply unscrew the old one".  If
it's been in there a while, it'll likely take a heavy duty socket and long
breaker bar to extract.  Some of the sensor's threads may end up in the
cast iron too.  I had to get a thread chaser (same as for larger spark
plugs, fortunately) and clean up the pipe bung before I could install the
new one.   This was a major PITA task working on jack stands.  I now have a
hoist and look forward to attempting the next one :~).
