Main bearing shells are color coded. Yellow is the thinnest material, green is in the middle, and white is the thickest. BMW recommends checking oil clearance with Plastigage for each crankshaft journal. Yellow is the default replacement, if your gap is too large use a green or white shell to bring it into spec.
