So I have tried everything I can think of while trying to install my O2 housing and it has been a bust. I cannot for the life of me get the bolt off on the bottom left (when looking at it from the engine bay) the one with the stud facing the opposite way of all the others.I have soaked the nut in 50/50 mixture of ATF and Acetone. I don't want to hear "PB blaster works wonders" because ATF/Acentone literally works 4 times better look at the study if you are curious. I have tried a wrench on the end of the nut from inside the engine bay no luck, couldn't get enough torque due to clearance. I removed my intake, used a 3/4in deep socket with 6in extension along with a foot of metal piping on the end of the ratchet no luck. (1/2in doesn't fit its too thick and hits the bottom of the turbo angling the extension and not being able to get on the nut). I am out of ideas and have no idea what I can do from this point I am hoping someone has some miracle trick to solve this big PITA.
