EDIT: quote didn't quite work.
Thank you Clan. I will unplug promptly. And when the time comes to fit a new sensor I will look for the clips. Stephen .

Hello
I am still applying PlusGas. Is the blanking plug perhaps needing an AF or BS/WHIT spanner or socket please? Stephen .

Lambda sensor connectors are on the bulkhead under the bonnet behind the Offside strut tower.

Thanks. Mine appear to bu in-line connectors in that place. Unless there are similar connectors in that area.
The hex of the blanking plug I can't get a fit for yet. I must be very tired 'cos I can't get a confident measure of the size yet. Stephen .

it must be very rusty now , its originally metric but use which ever socket is a tight fit even if you need to tap it on with a hammer.

If the worst comes to the worst I've always found the easiest way of unscrewing a rusty sensor is to remove the cat and whatever length of exhaust pipe is necessary, clamp the sensor in a hefty vice, and then use the cat/pipe as a lever to unwind the cat from the sensor.
The trouble with trying to apply leverage to the sensor in situ is that the cat is not rock solid - the engine and exhaust hangers move and absorb all your efforts. |

Thank you Heckflosse, Clan and Clifford

Oh yes corroded. More than I had realised. It has been decided as 17mm. I should have worked that out earlier. Age and health. I am continuing with PlusGas. Daily. And my 17mm impact socket is wall drive. My first experience of using a hex impact socket was dismantling an 1100 sub-frame, a seriously rusted bolt head. Impact socket, an extension, a "breaker" bar. Job done. So I do hope PlusGas and wall drive will do this job. I especially learnt the value of daily PlusGas doing 240 headlight removal, for reflector replacement. Perhaps Dave's magic mixture would help. But it is not the easiest fixing to apply a mixture to. And for me so far PlusGas is tried and tested. For me that is important. I am being patient with the PlusGas. When I eventually try to undo the blanking plug, I have a good impact driver available. Many micro impacts are a good way to deal with tough fixing undoing. If none of that works, whether to resort to a worn, corroded, &c remover extractor could become a cost decision. Having a new boss welded in by the mechanic could be cheaper than a set of extractors. All will be well, I hope. Quote:
The down pipe is fairly firm, and the impact driver has more hope than leverage, I think. Many strong swift impacts. ***** Early in this mini saga. I had a horrible chest pain. I am known to have cardiac "issues". It was probably angina. But. I am further below my best than before. Just to put the job in my personal perspective. And I acknowledge that some other members must have more difficult health than me. Obviously I am all the more grateful for advice. Thank you. Stephen .
