my 2000 jeep cherokee idles fine, but when you rev up the motor to around 3kRPM it starts ticking badly. i posted a video to show you what it sounds like.
removed the valve cover to check oil flow and rocker arm tightness
 

Did you figure out what the issue was?

Discovered few problems. Had sticky intake valve sleeve on cylinder 6, as well as blown out lifter and torn up can lobe all on the same valve. I'm mid process in rebuild. Just finished the head minus .012 off the deck, as well as getting the block cleaned up real good. All in all the project should be fun.
