Re: Changing oxygen sensor : spider 1986

["Jason Hagen" <hagen_jason1@domain.elided>]

Here is my advice:

Soak the sensor thread area with penetrating oil, each day, for several 
days.  Be sure to drive the car each day as well to help work the oil in.  
When you are ready to remove the sensor, soak it again and using an 
appropriate wrench, loosen the sensor incrementally.  Work it slowly loose 
90 to 180 degrees at a time, and rotate it back clockwise as well to help 
relief and release the threads.  Apply lots of penetrating oil during the 
loosening procedure as well.

Shouldn't be any need to remove the pipe or manifold from the car unless 
there is an access problem (like on my '88 BMW 735i which I am changing the 
sensor on any day now!).

Good luck.
