Blue smoke coming out from my bmw 320d e46
When I start the car quite a bit cloud of grayish
smoke comes out followed by blue smoke which
continues to come out. As soon as the enigne
warms up smoke disappears. I know it could be oil
being burned but could I Have all the possible
reasons please? Maybe its not oil at all? Also, once
someone told me that if you open the oil cap when
the car is running the oil should not spit. In this case
it does. But I have read a little but about it and
some poeple say it should spit (moving parts inside
it) and some people say it shouldnt (blowby gases).
Maybe it depends on the vehicle?
I would be greatful to receive some detailed answer.
Thank you!
