REMARKS :
#
machining of cylinder head can be required at camlobes
#
check distance between valve seal and retainer to be at least 0.6mm at full lift
#
VVT reprogramming, operating range adjustment or even eliminating the VVT system should be considered for camshafts with increased duration
#
Check distance between valves and piston to be 1mm at least with VVT engaged. Wrong installation will cause severe engine damage!
