Really 2 questions here: I have a relatively small oil leak around the base of where the oil check stick goes into the engine. Not big, doesn't drip or anything, but is this normal and if not, what to do to fix it? The other question is about the gold color on top of my engine. Was the engine supposed to be gold colored or silver. Can it be cleaned off? Why is it like that? Thanks
