I did an oil change on my quad a few months ago and ever since then I’ve had a small and slow leak from the drain bolt on the front. I first tried changing the copper crush washer, and I thought that was the issue as the washer looked warped and had a hole in it. Once I changed it I still had the leak. I then went to ride now and asked them about it and showed them some pictures. They think it is because the case is marred up. I tried to file it down and smoothen it. I have not put oil back in since, and it just had what was left (I only drained the oil from the front bolt, not the one on the side also). I put a new crush washer again and a new drain bolt. I just went to look at it and it looks like a tiny bit of oil is still leaking from there. I have no idea what the issue is at this point. I have attached some photos that show what it looked like before I tried filing it down.
