Top end noise?

Noise: Top end the obvious is the valves need adjusting.... not that kind of noise though. It is a deeper harder less frequent noise. no it's not rod knock. it sounds like the timing belt tapping the cover. that kind of sound. yes it increases with rev's and yes it is audible at idle. it's most noticable there. any ideas?? I'm going on a fishing trip tomorrow so after that i'll try to take a video of it so you can hear the noise. thanks guys

Are you 100% sure your valves are in adjustment?

Your problem could also be a bearing on a pulley going out. Timing belt tensioner, alternator, etc.
