Black often denotes too much gas in the fuel/air mixture. I'm not sure what that sound is, hard to tell. Almost sounds like a bad fan clutch (?) Some other folks might have a better idea.
I'd make sure those plugs are seated properly. Also, how much oil is it using? A little is OK, considering it almost has 170k miles. Also, mild oil use is one of the symptoms of worn valve seals. Not a big deal, btw. It's A DIY job and not too expensive if you bring it to a competent shop.
