I bought a blaster a few days ago and when i got home i realized it is leaking oil really bad from the cylinder where the pipe is and dripping down. i can see theres air coming out from there too. there is oil leaking from the silencer as well and i can see a little puddle of oil in the tip of the silencer. what can i do to fix this? i dont want to mess anything up but i also would rather not bring it somewhere to get it looked at and spend all kinds of money
