I bought my 08 SM about a month ago and I've been having issue after undisclosed issue with it (missing parts, rash here and there, cracks, etc). Most recently, I've noticed a lot of heat coming from the engine. So, I emptied the oil and replaced the oil filter to find that the o-ring inside the oil filter case was missing. And of course, only about 1 liter of oil actually drained out (did not smell like gasoline). Also, I noticed that these cracks had formed inside the oil filter case. Am I &%$#@!ed? Or are these cracks not a big deal?
