I was removing the o2 sensor on a 92 civic ex, 1.6L V-TEC, and it broke
in half! The sensor broke free and was turning, but then it got tight
and broke. The threads broke inside the manifold.
The center portion of the sensor is gone so there is a hole where the
sensor use to be and, of course, exhaust gasses escape through this
opening.

Any suggestions on what to do now (besides having a stiff drink)?

Thank you for your help.

Have a drink and then get a propane torch... a can of penetrating
oil... and a large "easy out"(available from an auto store). Spray
what's left of the sensor and then heat with the torch. Repeat this
procedure several times to break the rust/corrosion bond. Be patient.
After heat cycling perhaps 10 times... then try the easy-out in the
hole. Next time you attempt this... you should use heat/oil cycling
several times before the removal attempt.

Thank you for the reply. I've been hitting it with penetrating oil each
day since, and I will try to remove it within the next couple days.
I'll have to pick up an easy out first.

Thanks again
Dan
