Well, no matter what the nice part is you have them fixing -a- symptom
If 10,000 miles from now your warranty is gone, and the symptom persists,
it'll still get fixed for free.
I'm actually wondering if it's a valve guide seal in the cylinder head. Do
you think you could convince them to yank the spark plugs?
Come to think of it... take the free turbos. Smile and nod. Follow up with
them after you get the turbos. It'd suck right now to get bit by Murphy as
you make them triplecheck their diagnosis, have them say "Oh HERE is the
problem" and then have your turbos die 6 months from now after your
warranty is gone. Know what I mean?
