stumped.....
nope increases with speed as far as i can remember, thats why the cam chain tensioner seemed like it was the cause, but apparently its not. if its an exhaust leak then that would be great, just a good excuse to get a new mani when i throw on my ko4 and testpipe
it also seems to get louder as the engine heats up. thats why i questioned oil pressure. i run mobile1 5w30, with a bosch big ol' filter. i didn't notice the sound until a couple of oil changes ago, it just kind of came out of nowhere.
so car standing-engine at idle and you can hear the noise then its definitely exhaust manifold ( possibly a broken bolt or bad gasket or both) also the manifold could have a crack in it which would get louder with the heat on it ( the gap will expand ) but good luck and if its the manifold consider having it welded it will be cheaper
thank you good sir i will have to check that out. i'm really starting to doubt my mechanics trouble-shooting abilities. maybe i'll try and throw a sound clip up here for you and see if you still think the same thing.
hey avant80 & co.
how about my oil pump being the culprit? the mechanic I used did some phoning around and quite a few people seemed to think it was my pickup line/oil pump on its way out. this would explain the top of the engine not getting enough oil and making the valve train noise would it not?

this may be a long shot, but on my vw gti i had a annoying clicking noise that sounds alot like what your problem is and turns out to be my valves were sticking. i just ran down to discount auto and picked up a bottle of "valve medic" took two bottles but fixed it right up. i say for $5.00 it couldn't hurt to try.
