yes it can because oil cal leak into the exhaust system and contaminate the catalytic converter
Yes, an oil leak can cause damage to a catalytic converter. When engine oil leaks into the exhaust system—often due to worn piston rings, valve seals, or a blown head gasket—it can burn inside the catalytic converter. This burning oil creates excess heat and deposits that can clog the converter’s honeycomb structure, reducing its efficiency and potentially leading to complete failure. Over time, this can trigger the check engine light, increase emissions, and decrease engine performance. Addressing oil leaks promptly is crucial to avoid expensive catalytic converter repairs or replacements.
An engine that burns oil will usually foul the spark plugs. That, in turn will cause ignition misfire, higher emissions and likely damage the catalytic converter.
The life of your catalytic converter depends on the condition of the engine and the fuel you're using. If the fuel has the wrong additives, the catalytic converter can become plugged up. If the engine burns oil the oil vapor will build up on the catalytic converter and it can become plugged. Otherwise, if the catalytic converter isn't plugged, don't replace it.

The 2001 Passat wagon uses 5.7 pints of oil to 6.5 oil. Do not overfill as that may cause overflow to damage the catalytic converter.
No
The catalytic converter should be bolted onto the exhaust pipes. The bolts will have to be soaked in penetrating oil to be able to break them free, then you can replace the converter.
That depends on the engine and the fuel you've used. If the engine starts burning oil a catalytic converter can fail rapidly. Some fuel additives can also cause a catalytic converter to fail prematurely.
If the rings are worn and oil is entering the combustion chamber then yes it can destroy a catalytic converter one time.
Many of the compounds that make your engine oil work better on the INSIDE of the engine are also "poisonous" to your catalytic converter as your engine starts to use oil. The nice thing about catalytic converters, they burn unused hydrocarbons that come out the exhaust. You may not KNOW that your engine is burning oil until the catalytic converter gives out or even gets plugged up. Watch the oil level in the crankcase. If it drops with no evidence of leaking, it's burning and your catalytic converter will die.
The catalytic converters "burn" unused hydrocarbons, including raw and partially burned gasoline, and CAN burn small amounts of engine oil, providing that the engine isn't TOO messed up. But engine oil often has additives that can eventually destroy the catalytic converter. co and no is removed via Catalytic Converter
If the vehicle is smoking out of the exhaust, its not necessarily the catalytic converter. If the engine has an oil leak big enough to cause oil to be burned, it typically needs a rebuild and should be rebuilt as soon as possible. (If its smoking, this isn't a small oil leak) This can be avoided with regular maintenance as these problems are common on poorly maintained vehicles. If the catalytic converter is plugged its highly advised the vehicle not be driven until it can be replaced, however if what you describe is excessive smoking, the vehicle should not be driven too long in its state as you risk destroying the engine entirely. If it is absolutely nessecary, take frequent breaks, and monitor your oil level. If oil is dripping onto the catalytic converter and is burning off causing smoking, you should be fine, just continue to monitor the oil level, and be wary of a fire that can start due to high temperatures and a flammable medium. If you chose to continue to drive the vehicle in that state, its at your own risk.
