So I did an oil change earlier in the week, and apparently I have reused the crush washer too many times, when I got off work today I found a huge pool of oil under my bike! Luckily I noticed it before riding, since when I dumped the rest of the oil out of the bike I only had around 3/4 of a quart left. Found a bunch of replacement 12x1.5 crush washers at cycle gear for $3.99, I will be changing the washers every oil change from now on. I got lucky, but be careful when you change your oil! Change that washer!
