   Ok been trying to remove my lambda sensor from my manifold (Bank 1) but it aint budging at all
   
   Even bought that tool that is used to remove 22mm lambda sensors but it is just rounding the bolt off were using a 2ft length of bar on the socket but it just keeps slipping off the bolt!
   
   Could i just go and cut the full bolt off think that would get it off so i can fit a new one or even drill holes into the bolt and then just break away the bolt parts which are left would this be ok ?
   
   Thanks

   You can get spanners that are like a C shape on a hinge and undo nuts from like 17-26mm bolts.
   
   As you undo the bolt the C grips harder.
   
   I've always had a success with one.

   I took ages trying to undo the one in the centre section. Ended up putting the spanner on and giving it a short sharp wack with a big hammer and it cracked the seal and came off fine

   Got that C tool like says above.. Its an actual socket made for lambda sensors but they just slip off the bolt. Gonna just cut it off (Hopefully) lol
   
   If any small bits falls into the manifold downpipe will they just be shot out the exhaust ?

   I heated the manifold up by taking the car along the back roads and it still didnt budge
