2002 Honda Accord Question: symptoms and causes for a bad catalytic converter

 

Question

I've had high oil consumption, rough running engine which lead to a burnt valve - that was replaced and yet the problems still persist. Now I'm being told I need to replace the cat as it is not "clearing out" the build up. First, does this sound right and second, what other issues are caused by a bad cat? Thank you.

    Cats go bad when fuel is introduced into them. Oil too. We just replaced an engine that overheated and dumped the coolant into the exhaust system which went through the cat(s). After assembly we tested the cat and if failed.

    Before replacing the cat have all your other concerns addressed to keep the one working well. Happy Holidays
