even if you "expected more" in terms of good news, please do not select this option as it PUNISHES ME for my honest answer.
this is common on your engine
it is caused by bad valve guides, allowing oil to burn after idlling for a long period
this is a big job to repair, about $6000 total
make sure that the dealer tests the crankcase ventilation system, to make sure it is not causing the oil burning, but unfortunately the symptoms you describe are very common and point directly to the valve guides
I am sorry that I can't have better news for you, but I trust that my honesty and quick rseponse is appreciated.
Remember, a low rating PUNISHES me for my honesty - thanks.
