Default Valve adjustment or TCT?

Hello,

Lately my 2004 S2000 F20c engine is doing a sort of grinding noise. I searched on the internet and found that it could be either the TCT or the valve adjustments. I started with the TCT fix, sandblasted that worm gear and inside the piston but the noise is still there. Could you please verify whether the TCT needs replacement or the valve needs adjustments?
