Well De-cat actually.
Look at the following picture. Inside the red shape.

How the hell do i get that bolt with sensor off the pipe, ive had it in clams to have ablast at turning it from 1ft handles to spanners with 3ft of lever and it still not shift.
Im putting my cat back on for mot time.

8 views an loads of mechanical boffins on an no posts.
Ive done the soak it in WD40 thing and the try an tighten it then loosen it. ive knocked it with a hammer, but will it shift, not even a soddin mm.

Anyone got a spare lamda sensor for sale cheap as i aint paying some £60 for a new one.

clamp the hole decat into a bench or vice, then using a monkey wrench (plumbers pipe wrench) get a good grip round the part yu want to twist and very slowly tease it free, this always used to work for me when changin lamba's i found it the only thing with any decent teeth and ability to grip the nut, espicaly when its all craped up like that,
if that dont move it then its gota be taking it down the garage and get some O2 heat on it, hope this helps

I think its going to be the O2 route then, ive had it in clamps with a monkey wrench as its was the biggest thing in the shed.

WD40 is not half as good as freeing things up as people think. By a can of spray 3-in-1 penetrating oil. Penetrating oil will get in there way more than WD and will be much more likely to free it up.

Put a spanner on mine and hit it with a lump hammer. Took one hell of a whack but did come off!

yea i think heat is going to be your best bet, if you have a flame tourch clamp it and heat it and spanner it lol or garage

Heat it and beat it.
