Yes I've searched and read. No, nothing was matching my case:

I think this is not normal even if not so much annoying...
When I start the car when cold, for a couple of seconds there's some smoke, then AWS, and maybe still some minutes after ( when gettin' warmer ) it's smoking a bit blue. I smell oil, wich is ok, but I fear there's something bad to come...
The car is 80.000 miles, the engine I don't know.
A picture taken maybe after 2 minutes engine has been started.
