Hello!

So after owning my bike for about 3 weeks now, I noticed that there is a "slight" oil leak.. I couldn't understand where it's coming from, until I noticed it dripping from a bolt

Upon closer inspection, the bolt has somehow managed to strip inside the (block?). When taking the bolt out I saw little thread shavings from it stripping, now i'm not sure if this is bad or BAD.. How easy of a fix is this?

This bolt is situated right next to the gear lever.
