Having killed the sensor drifting the corroded exhaust downpipe studs out to replace with a set of stainless bolts and nuts efforts to get the sensor out using a selection of cut away lambda sockets which only slipped off the flats and rounded them off has been a right pain.
Just bought a set of Extractor Sockets that have spiral flutes inside that bite into the flats the more force you apply to undo the sensor. I already had a smaller set but the sensors flats are 22mm my set only went up to 19mm. Got mine from Amazon but they are available on ebay at a cheaper price. Will have to cut off the top of the duff sensor to get the Extractor socket on its flats but as its dead thats not going to be a problem.
Should be able to get a breaker bar on it to exert a good amount of force on it to get it turning. Space is tight but hopeful I can get enough swing to start it moving. Will apply some heat from my Map Gas Blowlamp as well which should assist. Will report back on how these extractors perform.
