This week on Car Talk, volcano tracker Bill returns from the increasingly lava-laden shadows of Alaska's Mount Redoubt, for a round of Stump the Chumps. Did a pair of Hanes hose-top really help ash-proof his Subaru, when the volcano blew its top? Find out.
Also, could a dealer actually conceal the sound of a failing muffler with... seed corn in the air filter? Plus, a sisterly prank with a spoon goes awfully awry, a turn of one wrong bolt ruins an entire brake job, and another reason not to let a guy with hairy knuckles install your new clutch. All this and more, this week on Car Talk.
