Exclamation BMW 645ci N62 blue smoke warm engine

Hi guys,

I'm having blue smoke trouble with my car. There is no problem with a cold start, but soon as the engine is on temperature it blows blue smoke when I hit the gaspedal.

I've allready checked on the internet what the problem could be. But here's the thing, the blue smoke only comes out of the left exhaustpipes (driver side)

Does anybody know what it could be? I know I'm burning oil but dont know where. I'm reading something about a alternator bracket on this car, if it's leaking here could it burn oil?

Allready changed:

- valve cover gaskets both side
- uppertiming covers gaskets
- vacuum pump o-ring and gasket
- oil sensor

If my questions make me look stupid, please know I'm not a mechanic and just want to learn more about my car

Thanks for the feedback, I've read some threads about valve stems and I will bring it to a mechanic to check if this is the problem.

I will check it Able thanks

Forgot to reply back on this problem.

Brought the car to the garage a couple months ago.
The problem was one of the valve cover gaskets. This one was leaking oil (again). The mechanic replaced it with a new one, changed all sparks and new oil and filter. My car is blue smoke free now and I'm glad that it wasn't the valve stem seals.
