Well I have tried to shift the one reasonably accessible o2 sensor on the car (3.2 petrol) and it is not budging.
I used a WD40 Penetrating spray, 2 or 3 times over the weekend and had a couple of different o2 sensor tools connected to a 15 cm socket and then a longer torque wrench....NO GO.
I have a breaker bar coming today in the post, which might improve the leverage a bit, but are there any other tips that you all may have to get the f*cker loose?
