This week on The Best of Car Talk, despite the best efforts of every vice-grip holder in a 30-mile radius, Lyle can’t move her truck’s dipstick. Is her only option to turn the truck upside down and hope gravity does the trick? Meanwhile, the laws of space and time are being challenged in Colorado, where Ian’s girlfriend’s odometer is spinning backwards. Should she trade her car in before or after it hits negative numbers? Also, Jay’s Civic was running perfectly until he attempted some DIY maintenance, and now the car is revving high and getting lousy gas mileage; Erin’s turn signals fail if she turns on the high beams in the 3-tone Impala she inherited from her grandfather; and Steve poses the philosophical question, why do bad things come to cars in the threes, in the worst possible weather? All this and more, this week on The Best of Car Talk.
