Cracked head ? So my buddies 08 L has a very small ( tbl. spoon @ most )of oil coming from the head. Specifically, as you sit on the bike, the left side. Buried in behind the cooling fins is a rather deep cavity. There is oil seeping from said cavity. The only thing I can think of is that he has a cracked head. Has anyone seen this particular location weakened / cracked before ? Is this a known weakness in the casting ? etc.. ???
