I had this knocking rattling noise in my cylinder head after I took it to the track a few days ago. I was told to remove the valve cover so I did. What I found is what seems to be the two springs over the fourth cylinder under the cam closes to the fire wall, are rubbing up against a hump inside the inner front wall. There was no clearance. Wich would kind of explain the rattling noise, Kind of sounds like when you put a card in bike spokes. It does it when the car starts and under acceleration. There were a couple of scrathes on the wall in front of the rockers also. What would cause this, and waht do I need to do to fix it?

Do you
have the same problem?
