Check to see if you have vacuum when you open the oil fill cap if so, you may have an issue with one of the breathers and the valve cover for the check valve on top of the valve cover
I really hope you guys can figure out what caused this😢 Matt looks upset which I feel to personally, such a beautiful car but I know you guys can fix it ❤️🔥💪🏻
Seeing you guys do this reminds me of what I’ve gone thru with my F10 M5. I sold it and bought a F90 M5 I love them and can’t stay away from them both my favorite M cars
