Hi there. I have the ultimate piece of junk, 2003 X5 4.6. Don't get me wrong... it's nice to drive. Just wish I could get more than a few days out of it at a time. Latest complication was quite similar to this thread. I live in edmonton, alberta. Things got cold and I had a ccv freeze up, blew the valve cover gasket, and it puked oil all over. Took it in to Eurasia auto where one of the guys (Ralph) was a service mgr at a bmw dealership. $700 later and it's fixed. That was a week ago. Today I am driving and a huge cloud of oily smoke blasts out the exhaust pipes. I found oil coming out of only the driver's side tail pipe, but oil burning smell coming out of both. I got it to a heated shop, let it unthaw and restarted it. Tons of oily smoke poured out the pipes. It seems to run ok otherwise, and doesn't have any horrible noises. Any suggestions would be greatly appreciated! Thanks.
