When your own station's Web site singles out your "off-beat delivery," you know they're not talking about the recipient of a bachelor's of broadcasting degree. That's exactly what we like about the quirky Scotty Kilmer, the car-care expert who hosts the twice-weekly taped segments. But it's during his Saturday-morning live appearance answering viewer calls that the Guru of Gaskets really shines. As disembodied voices attempt to imitate the sounds of their cars' various ailments ("Scotty, it goes wrrr-wrrr-wrrr-ch-chunka chunka! What do I do?") Kilmer is fast with his simple, direct answers and explanations, all delivered with flailing hands, darting eyes, odd voice modulation and not-meant-to-be-funny pronouncements ("Check your dipstick, it might be foamy"). After he gave instructions during one recent segment about how to start a flooded car, the befuddled caller asked, "So, it has something to do with the spark plug?" That's right, lady. And bonus fashion points to Scotty for wearing the gold-stud earring.
