Anyone else have a throttle plate crack? I noticed a 1" crack in my throttle plate. On the top the crack runs from the edge at about 45 degrees but on the bottom it appears to be at 90 degrees. The is no performance degradation and the crack appears to have remained the same for a year. How concern should I be?

Crack or scratch from top. Is that a small chip or machine mark?

Crack or scratch is barely visible from bottom

What's a new one run? Seems like a pretty straight forward job...
