Went to add some oil to the SC today and it looks like my oil cap is busted. I turned it a little bit and then heard a snap and now the top of the oil cap just spins freely without opening. I tried to pull it a bit, as well as push it down and see if it locks into something, but nothing. It just spins freely, I can't open the damn thing up! I don't recall it doing this last time I opened it up, so I don't think I'm having a brain fart and just not remembering how to open up a simple oil cap. So how can I get the thing open and until then, can I put some oil down the dipstick tube?
