broke oxygen sensor post - Toyota Nation Forum : Toyota Car and Truck Forums

Hey, guys!
I used to much force and too little Liquid Wrench/WD40 when trying to take off the nuts that hold the oxygen sensor in place on the catalytic. One of the posts broke off.

So, now the oxygen sensor is just being held by one post thru one lobe and 1 nut when it should have 1 on either side.

will this cause and air leak/vacuum?

Any suggestions for repair? a self tapping screw for metals?

This is for a 88 camry, manual trans., 193xxx miles, non california.

thanks

This can cause exhaust leak.
How far from the flange did the stud break[is there short stump sticking out, or it broke flush with the mounting flange]

looks like its pretty flush. no stump. clean.

would this cause oxygen to enter and cause a false reading and increase HC?

This most likely is a screwed in stud. If so you or a shop may be able to remove the old stud and install another.
