It sounds like you have a rod problem. If that is the case the engine will need to be taken apart to be fixed. Price varys from shop to shop but they can do a bunch of tests on it and tell you exactly what is wrong with it for about 80 to 100 dollars

Sounds like a vacuum leak. Raise the hood while your engine is idling and see if you can pinpoint the area. Chances are, you'll find a vacuum line with a hole or loose connection.

So does the a/c still work, maybe your compressor is bad? Top off your oil and run the engine and see if you can find out where the oil came from?
