I just bought this minivan2 days ago, it is in great shape like it was well taken care of but now I have noticed apretty distinct knocking in the engine, it sounds like it is coming fom under the back (engine is sideways) valve cover. It almost sounds like it is knocking right on the valve cover but it is hard to tell because the air intake sits on top of it. Does any one know what this might be. Thank you.
