Should I do something?

Upstream o2 sensor. I guess I need a head gasket? I am blowing a small amount of white smoke when cold but I've changed the oil a few times and haven't seen any coolant. How hard are head gaskets to replace on the 3rz-fe (2.7 in first gen tacoma) Here's downstream

I'm replacing the Cat because of a code and the rest of the exhaust with it.

First question to ask here, are you actually losing coolant?

If not, do nothing. If so, how quickly? And does it misfire for a little bit on startup when it's smoking?

You might consider a cooling system pressure test and a "block test", which checks for combustion gasses in the cooling system. That sensor doesn't look that bad to me. Colors and deposits will vary on/in exhaust parts for lots of reasons.

You might want some new tires too.

I just got new tires thought. The one in the picture was the spare spare I took off because it's useless.

Make a swing out of the old tire. It's not good enough to be a spare's spare.

I meant to say spare. Mobile Kinja likes to double my words.
