man i had the same problem not too long ago, some mech told me it was the timing chain tensioner...its like 100bucks but then before i was going to get it fixed, the sound totally went away...it was weird and the prob tripped me out too...mine wasnt comming from the intake side tho, it was from the other side of the engine but it did make a weird ticking sound...and it went away after like 3000 - 3500 rpm :-/ hope that helps
