d) buy & install a post O2 bung extension that is shaped like an L, in order to get the O2 sensor out of the mainstream of smoke. (It will fit; I am currently doing this)
Do not do #4, it will fuck up your fuel trims. The rear o2s have to be in the exhaust flow same as the front, checks and balances against each other.

I’m sorry for the late reply, but I already replaced all 4 a while back. It still kept showing up but then magically disappeared haha
