O2 sensor rusted bolts

The OP doesn't have nuts on the sensor studs. They're gone. Check post 1 & 2. His best bet is to use a stud extractor.

 

If it works this might be better than grinding.. And note this was in reference to the note about how to remove a nut if you have one. Obviously not about the case where there there is no nut.


Note, i have never used one and dont own one but what about using one of the nut splitters to get that nut off??

 

looking at this and the fact you are asking.

The easy way is just replace that pipe and be done.

A new sensor is needed .

Having tried every other method replacing the pipe is the easy way if your truck has the California emission package.

 

it’s all welded together . I don’t think it’ll be easy . I just let it fo but now it gotten worst and I’m gonna heat up the rust that’s there and try to either use a stud removal tool or if I can get the rust off just pull it off but I need new studs anyway .

 

I gotta get that rust of its like a rust weld between for the o2 sensor down the plate . Can’t pull it off without breaking the rust free . I got an angle grinder but it’s big as hell I need small space

 

Do you have a file? Just get in there and hit 'em with anything you got. You have to replace the studs anyway, it's not like you're trying to save those threads.

 

local shop swapped the pipe and a new flange deal for the sensor.

Installed the sensor for me as well, IIRC $120 cash.
