If the engine has a lot of miles it wears out just like everything else. If the mile are low, or may have a bad O2 sensor, which will make the engine run rich and sooty and can ruin a cat fairly quickly. If the engine burns oil it can also damage it, make sure to change the pcv valve if it hasn't been changed in a while, it will make the engine use oil.
