Decided to buy a replacement evap valve to fix it (only to find out that the previous one was stil working as i couldn't blow through it).source ↗

Threw the new valve on there regardless but noticed i have nicked it as seen in the image.source ↗

I never work on cars as i am not a mechanic i went into this knowing full well isues could happen.source ↗
