Alright, so my car not only misses a lot but when I drive, white smoke is coming out and my fuel is getting chewed up like popcorn. Oil is also where it shouldn't be and I'm led to believe it's a blown cylinder. Could it be anyother problem besides this?

blown head gasket perhaps

Define oil where it shouldnt be...

Check the coolant. If you have a cracked cylinder, you'll be low on antifreeze. Same with gasket. The smoke you see is most likely the gasoline burning, which is why you have bad gas miledge. The best you can hope for is the carb to have taken a dive, which would cause those issues, minus the oil.
