Hi. I have only had the car for about four months now, and it has just recently started to make this ticking noise thats coming from under the valve cover. This only happens when the car gets driven around for awhile. I have already checked the timeing. I also pulled the plugs and noticed what bad condition they where in. so I changed them. But that didn't fix it. Do you think it could be valve chatter?

 

Adjust your valves y0!
