So recently when ever i start my Z it grinds for less then a second.

This grind sounds like metal on metal and can somehow be felt in the clutch pedal.

I just removed the starter and inspected it, teeth a fine no unusual wear. Went ahead and had it bench tested as well, and tested perfectly.

So im at a complete loss on what it could be any insight would be great.
