Hey guys, I need some help with ideas as to where my ticking noise is coming from. I have 1.6 scorpion rockers, and trickflow heads. I have a slight ticking noise that I can hear from inside the car, and is also noticeable on the outside. It sounds similar to an exhaust leak, seems to be isolated to the passenger side. I've pulled the valve cover and it doesnt appear to be a loose rocker seeing as how that is much much louder. Any other suggestions?
