REMARKS :
#
camshafts for use with STD VVT (vanos) system
#
The VANOS (VVT) system on the intake camshaft changes the PD from 117° to 92°.
The data are shown for full intake retard (disengaged VVT). Check distance between valves and piston to be 1mm at least with VVT engaged. Wrong installation will cause severe engine damage!
