45 degrees or so. If its not that then why else would the fan not come on. I am tempted to jump on rock auto and order a fan clutch and thermostat. I want to just replace everything that could be a problem at this point.

I believe my Jeep is running rich. I can smell it whenever it's running in combination with some burning oil. Not getting any codes. 94 with 200k.
Any ideas?
Any way to tell where I'm burning oil, like rings or valve seals?

When do you smell it. When first starting up on a cold morning or after driving for an hour

O2 is probably 18 months?
I can see blue smoke in the mornings since it's been cold and I could see it while the engine was warming up.
I recently replace the CCV valves on the cover, lines and intake had a bit of oil in them b

A compression test with oil would also be a cheap way to tell. If it's your rings you'll see a jump in compression in a wet test vs dry. Could still be valve seals too lol
