Smoke cloud at cold start

[grounch]

Hi

Have some concern about my recently acquired 2005 3.0dA E53.
When i start it after let it sit all night, it launch a cloud of smoke:

Doesn't smell much like oil, i had a civic with oil issues in the past so i know what burned oil smell.


I drove 5min and stopped to check again, almost no more smoke when revving or starting it again. Temp past the blue on the gauge.

Warm start: https://youtu.be/VrZe4QJZGlQ
Revving: https://youtu.be/O7o1-EZQuR8



Could it be the pcv valve that's too clogged and not functionnal anymore, leading to oil deposits after turning the car off?

Or bigger issue like turbo?

Drives fine, no big smoke even when flooring it (maybe i can't see it if it's thin smoke, but no big cloud like on the video).

thanks
