we are running out of ideas...

im having valve problems. int he video, you can hear a "chatter" from the exhaust valve on number 8 cylinder. no matter what you do, it will not quiten down. we thought, maybe the cam lobe wore off. but we checked it by measuring a rod (dubbing as the pushrod) ontop of a good lifter at TDC and then at the bad one at TDC. same thing. now, since thats eliminated, thiking that it could be a valve thats either burnt, hitting the head, or a guide is not seated properly. you can put pressure on the sping while the car is running and it hushes up.
and before anyone asks, its not loose header bolts.
