x5 4.4i v8 smoke problems PLEASE HELP!

You are not going to like this.
Mine did the same exact thing. It was the dreaded valve stem repair. ($3600) at indie garage. As soon as I mentioned it to my mechanic he knew what it was.
I asked him if I could just put it off since it ran fine. He advices that the extra smoke can mess up the catalytic converter. What I did was that I trusted the little indicator regarding oil change. I think that was a mistake in that I drove way too long between oil changes.
Hope that helps you.
