I'm looking for someone that knows how to diagnose the smoking issue. It is burning oil when it's smoking, the smell is so evident.

Last year it would smoke about 2-3 minutes after starting the engine and it would do it when I would stop for more than 5 sec., I resolved it by replace with a new valve cover. I drove the car for about 8000km and the smoking is slowly creeping and now it is back.

It is either a leak with the pcv system or a turbo is about to go.
I've tried the RB pcv valve, I've even tried the external pcv setup, and the smoking is there.
