It is a 2.4 liter, 4 cylinder-was told i blew the gaskets because exhaust is blowing clouds of white/gray smoke, along with a little water and oil, and it runs rough-was told replacing gaskets or trying to rebuild engine would be really expensive and was advised by many to buy a used engine instead-thinking of getting one online, so many to choose from, not sure on warranties or prices, or even a good company to go with it-i'm open for suggestions-please help a girl who knows nuthing and is tired of the run around and rip offs!!!!
