I can't explain it either. I thought the AFM was operated by solenoids and a valve body in the crotch of the cylinder bank. The cam "sprocket" looks like it could be one of those hydraulic cam phase changers that are used to vary timing, but of course without individual intake and exhaust cams, it would phase shift both intake and exhaust lobes simultaneously. Anyone know?
