I pulled off the intake manifold to do the dual pass mod and noticed a yellow film coating the inside of it and some tiny black debris. It looked almost like oil, but when I plugged the inlets of the cylinders and removed it, it looked like a yellow film. The supercharger side of the intake manifold was immaculate, but when you look on the other side and down into the manifold you can clearly see some black debris.
Did anyone else find this in their car? I only have 21k miles.
