[Shop-talk] What fun - O2 sensor

[mark at bradakis.com (Mark J Bradakis)]

I need to replace a failed oxygen sensor in my old S10.  Should be
a simple task - fat chance! There's just so little clearance that when I
do get a wrench or socket securely on it there's no way to get enough
torque applied to break it loose.   Heat, penetrent in various combinations
and cycles have not made it any easier.  Sheesh.

Sorry, I just had to vent.
