ok my car was running i reved it up and then it had a hard time reving above about 3500 rpm actually wouldn't rev over that now the car wont run it cranks over i hear like a banging sound under the hood?????? also it did start and idled at like 400 rpm for a few seconds then quit and when i gave it gas it did nothing and it does start a little but just revs to like 200 rpm and dies right away and the engine is also kicking and there is oil on the ground under the exhaust manifold and it smells like oil

 

is the car turboed?
