Question: why does my car smoke?

it smokes when it idles for a good period of time. its an older big body grand marquis and im not sure if its possibly the valve covers having a small hole in the gasket(s)? also it has excessive oil consumption as well. i have went underneath the car and essentially everything on the bottom of the engine has either caked on dried oil on it or has oil leaking from it. i have seen oil dripping down from a small hole in the oil pan that im about to change this weekend, but im not completely sure thats the only spot. when i drive i can smell burnt oil as well from time time, not all the time though. any info would be great appreciated and thanks for your time

Smoke from the tail pipe: This could be valve stem seals, piston rings, or a PCV problem.
