When the car gets to 2500rpms and the gas is released the engine will tick till it gets to 2000rpms. I put oil in it and it stopped then about a half hour later while driving it started making a loud knocking sound. The sound is coming from the top end I took the valve cover off and nothing is abnormal and nothing is loose what might cause this?
