What happens when you put too much oil in a car?

Overfilling your engine with oil can cause the oil to foam and get sucked up into the crankcase ventilation system. This is not a good thing.

A severe leak on a long drive can drain enough oil from your engine for damage to occur.

How will overfilling the engine oil damage a catalytic converter?

Your biggest problem with overfilling the engine is not damage to the converter but damage to the engine itself. Overfilling causes the crankshaft to make contact with the oil. This will cause a situation where air will be mixed with the oil. This air mixed with the oil causes the oil to lose it's lubricating properties as air is a poor lubricant. This will cause the engine to overheat and will result in severe wear to all moving parts within the engine. If you overfill the engine drain the excess oil out immediately.
