Hey everyone first post.

Getting blue/white smoke after driving car for a while. Only on acceleration. While driving with my wife following she says it smells like fireworks but no smoke. Took to BMW their pretty sure that it is the valve stem seals. They also think the guides as well. Now the kicker. Extended warranty from third party will pay for seal replacement but not the guides. Bmw is saying they would need to tear the engine down to tell for sure. If it's only valve guides I would have to pay for everything. Seals, warranty pays everything else I would have to pay for the guides 500 bucks. That's the background. Question is. . I'm burning oil, can the guides be bad without the seals being bad. Overall is about 7 Grand.
Car has 90000 miles on it. Love the car just wondering if I should chance it.

There is a possibility you need guides and if so the seals are a given (they have to be replaced if doing the guides). Here is where all the controversy comes in. What I have found is that the majority of BMW mechanics - right off the bat say - you have bad valve stem seals / guides. Here is a copy from a BMW Service Manual which needs to be addressed before an engine can be condemned with bad seals/guides. This is true with any engine and hopefully you get a honest diagnosis.
Note: If the exhaust system produces blue smoke, it is necessary to check whether the engine is also drawing oil into the combustion chamber through the crankcase breather, which suggest that there is a fault in the area of the crankcase breather. A clear sign of a problem is an oiled up clean-air pipe.

Thanks for your Response! Car has been at NEILLO BMW for the last 5 weeks (long wait at machine shop) bad valve guides and of course seals. Also some leaky gaskets, front struts, bushings. 9 Grand total covered by extended warranty.

Who is your extended warranty through? What price and how long as well? Thank you

Purchased it when I bought the car. The contract says 2907.00. Its from protective/western general. When I bought the car I was offered the mileage plus contract, but they have a bunch of others I would have liked to have been told about. Ill put the link to their site. Mine was for 2 years or 24000 miles and covers gaskets/seals for 150, 000. I had 4000 miles left when the blue smoke started.http://www.protectiveassetprotection.com/Products/Automotive.aspx#Automotive_MileagePlus

Thank you! Ill look into it. I have 106K miles on my 06 750li. Contemplated selling it due to the presumed valve stem and mechatronik sleeve/adapter issue but got in contact with bmwoem1 and once I get back from Afghanistan, I'll be immediately taking it to him for half the price the dealership quoted me to fix the valve stems.
