It's good to know that the car has been by and large reliable.
And if you ever pull the valve cover at any point, would love to see the insides. I believe that the BMW OCI does a good job as long as you stick to the right oil and filter, and seeing pics of your head would be a good reaffirmation.
BTW, I betcha BMW would be willing to buy that car back for analysis and hook you up with an F30..
Single-owner car, clean history and regular maintenance on schedule..
Sammk, here's the valve train at 100,000. No sludge back then, and no sludge now.
And this is a pic of my Wife's Z3 valve train in April 2012 when I did the gasket. The Z3 has BMW OCI's around 10,000 miles and he car sits quite a bit and gets driven once or twice a week at about 40 miles a trip.
