They ’re easy to check , though , and cheap to replace before they flush it . Dry - rotted gaskets can allow vitriolic throttle to seep in and lento destroy your catalytic convertor , which is indicated by a rotten egg / sulfur odor . If an exhaust multiplex gasket give direction , you ’ll likely hear a " fffttt " dissonance that sounds like a combining of blowing and flapping , most detectable when the motorcar is baseless ( at a stoplight , for example ) . If this gasket is worn , your motorcar is leaking very hot chemical substance , including atomic number 6 monoxide , that can have fateful consequences .

Metal should be checked over for corroding or impact damage from rocks , speed bumps and the alike . ( Do n’t get near a hot exhaust fumes , though ! ) If you live in an area that use route Strategic Arms Limitation Talks in winter , frequent washes aid transfer the buildup that do surface corroding . you could also interpolate your drive habits to tighten untimely damage . deflect myopic trips with no warm up - up period , because this allows acidic moisture from the locomotive engine to bite out the catalytic converter . Modern organization are make to withstand such heat , but allowing the car to warm up before take off might help avoid inner corroding [ source : Allen ] .
