JonS,
My experience is exactly what BlueStreak was talking about....with the twist of catastrophic failure in the end. I don't have any idea regarding frequency of total engine failure, as I only know that in my case it got really ugly.
Don't like your dealer? Might be time to try another. And is any of this work worth the hassle? Absolutely. Keep in mind your car is practically new. I personally couldn't bear to have 11k on the clock and noise like that every morning.
Good luck with this....
-Kurt
