Yes it can if the oil gets in the catalytic converter when due to bad rings or head gasket burned the oil gets on top of the pistons!

Can an oil leak damage a catalytic converter?
yes it can because oil cal leak into the exhaust system and contaminate the catalytic converter
Will a vacuum leak cause your catalytic converter go bad?
It is possible but highly unlikely.
What would cause a noise around the catalytic converter and up toward the motor?
most likely the converter is plugged up and caused a leak in the flex pipe
Will a code po455 show if car has a bad catalytic converter?
No, that code is for the evaporative emissions control system in the fuel tank. It has nothing to do with the catalytic converter.
Where would coolant leak from if dripping over the catalytic converter in a 2000 Ford Tauraus?
From the water pump
What causes code P0174 Bank 2 lean?
catalytic converter, oxygen sensor, exhaust leak
What is the P430 error code on a 2003 Toyota Highlander?
That code means that the oxygen sensor downstream of the catalytic converter on bank 2 is detecting that the converter is not working as efficiently as it should be. It could be a bad oxygen sensor, a bad catalytic converter or and exhaust leak.
How and where do you punch holes in a catalytic converter on a 2001 jeep grand Cherokee?
You don't. One, it is illegal. Two, It would cause a exhaust leak that if it got inside the vehicle would be poisonous to the driver and passengers.
Where is the oxygen sensor switch located on a 1989 Chevrolet Caprice?
All Oxygen Sensors are located in the exhaust eitherbefore or after the catalytic converter. Your O2 sensor may not be defective as a vacuum leak can cause the code.
Will a upper trans cooler line leak cause any damage?
If you run the transmission low on fluid you can cause damage. Fix the leak.
Why would the air smell like exhaust when you turn on the heat?
most likely you have a leak in the exhaust pipes or a bad catalytic converter
Why will a lean condition cause a catalytic converter to turn red?
The catalytic converter usually has an Oxygen Sensor before and after the converter. The hot exhaust gases of the exhaust heat up a catalystic and the voltage is proportional to Oxygen. By measuring before and after the catalytic converter, you have a sense if the Catalytic converter is working correctly in cleaning up the exhaust. The exhast to be cleaned up correctly requires the PCM to sometimes run Lean fuel mixture, to clean up NOx, and sometimes Rich mixture to clean up HC (Hydrocarbons). So PCM cycles the fuel mixture between rich and lean many times in the process of driving, so that to get optimal efficiency of the catalytic converter. However, if you have a vacuum leak, your engine will run LEAN and the PCM will compensate and force it to run rich instead. After a while, by running rich too much, you are throwing unburned fuel into the exhaust pipe, causing Catalytic converter to become Red hot and causing it to fail. So in short, running Rich, not lean, can cause converter failure.
