O2 Sensor...

O2 Sensor...
I've been dealing with a CEL due to a bad O2 sensor for a couple years. So, I've been treating the thing with penetrating oil for the past few days and finally put a wrench on it last night.
Well, it just crumbled. The threaded parts stayed in place, the rest practically fell off. So, I can't pound/drill it out as it's facing upward.
Do I drop the exhaust for fear of cracking the downpipe? Or, do I just order a bung and weld it in on the side of the pipe that I can easily access?
I'm going to try the latter with . I hope it's the right size. If not, I'll try other sizes. For $7, it's not a painful experiment.
Anyone know the thread size of our O2 sensors?

I tried to do my car this weekend and found the threads to be 12mm. I have been unable to find an extender with the 12mm threads. Has anyone had any luck with this? Where did you get the extenders/spacers?

I have been unable to find any 12mm extenders and am considering using one or two 12mm bolts welded together to get the spacing.

May or may not be aware of the connector ready Bosch # 13789 equivalent to the Denso and it would save you some big money . Spark plug Autolite #4163 has the correct 12 mm crush washers if they are missing . Anti - seize is not a bad idea for in service removal , careful not to get too much on and contaminating the sensor . Proper connector hookup to the correct connector is important and may be a source of problems although I have not experienced it myself . On the AJ16 engine the #1 cylinder is the forward most position ( opposite of the AJ6 ? ) . So the B1S1 ( bank 1 sensor 1 ) is on that pipe forward of the forward Cat . B1S2 is aft . On the ECU side of the connectors they have the same wire colors with exception of the one important return signal wire to the ECU . B1S1 Green , B2S1 Brown , B1S2 Blue , B2S2 Red . Not to be confused with the term orientation as this is a requirement to have the Jaguar shop " match " the changed sensors with the ECU under certain ( unknown to me ) conditions . Some readers may already know this but this information is for others that are new to this . Hope this helps some people . The old original sensors can be cleaned or refresh to possibly give you more service life by soaking overnight in some gasoline ( small baby food jar ) periodically tapping out softly against your hand and re-soaking a couple of times . Don't get the wires wet . Seafoam product seamed like a good idea ( their label says it is safe ) but I was able to get so much deposits out there may not have been anything left to clean . The sensors can be bench tested with a propane ( not high temp welding ) torch to get them to operating temp and deprive them of the O2 which then can be read with a digital multimeter . But then again they could be " out of range " . Look for some corrosion of the B1S2 and B2S2 connectors behind the back of the valve cover .
