Engine Opened~
They opened the engine and invited me to take a look at it, and here are the pics.
They say they have never seen it before, the crankshaft bearings for the 1st, 3rd, and 5th bank are partially welded shut so they seem. I do get my oil from Costco, but it's Mobil and says conforms to BMW spec. LL01. I don't know if that would affect anything....
