I had AEM Cam gears installed on my Prelude over a month ago. I haven't driven the car a lot lately because my parents gave me there Jeep Grand Cherokee. When I start up my car I hear a noise from where the Cam gears were installed...at least where the plastic cover was taken off. It sounds live the valves...but I do not hear any knocking. It is more of a humming noise. Is the engine noise that I am hearing supposed to be louder now that the cover is off or do I need a valve adjustment/valve lash adjustment?! Any feedback would be great. Thanks!
