I'm with Jim on this one, a tap is the easiest and cheapest option and
should be tried first. The last oxy I had come out hard(200tq) looked a bit
mangled on the sensor side when removed, but a tap revealed that most of the
*damage* was on the sensor side, not the downpipe threads themselves. Always
worth a try.
