car has o2 sensor codes on check engine light. car runs good but, once the engine gets hot, it started to smoke from the exhaust pretty consistently but mostly when accelerating. not super heavy smoke but, it’s definitely there. i’ve heard of issues with the PCV Valve so i upgraded that with a metal one and idk if it fixed the issue. i just drove it around for 20 minutes or so and i didn’t see any smoke when accelerating but it is also night time. however, once i stopped at a stop light on my way home, i could see some smoke as there was a car behind me with their lights on. im not sure what the cause is, please help me, i don’t see any oil leaks in the drive way or engine bay… also im new to BMW scene so please forgive my ignorance

the night time video is after the PCV Valve upgrade, the daytime video is before

Need a bit of history on the car. Is this a used car you just bought? How many Miles? Is a white or blue smoke?

Okay sorry I have re-attached video with this link so hopefully it works now. Just bought the vehicle, 76k miles.
