A valve adjustment would probably help out but honda valves are notorious for being loud at cold start up.

and accord f series are dubbed "sewing machine"

the mechanical valve are known for being noisy, get a valve ajustment if you haven't already got it.

if you have a 5th gen v6, the hydralic valves are known for ticking when warming up under light load

Is it a Loud, deep knock? Or a higher pitched "Ticking" noise?

the noise is not too loud but not too low right in the middle. it sounds like its hollow inside or something.. i guess you can call it a clicking noise but it goes away.

Sounds like valves to me, I would do a valve adjustment but like I and others have said the f-series motors are notorious for being loud.

it kinda makes sense doesnt it? of course your car is going to be louder when you start it, from a cold start my honda 5th gen is very loud, just like all of them just about, i can hear my car warming up all the way across my yard loudly, thats what it does, when it warms up it purrs like a kitten , sounds perfectly normal to me, but if you want to be safe go get an adjustment

as eeryone says most likely it is the valve lash a bit loose but i have seen the same kind of noise pattern with Piston pin slap,,

I want to get my valves adjusted,
but I just spent all my money making the dang thing pass inspection. (320k miles, totaled twice, different engine than original)
How hard is a valve adjustment? I mean, I do 90% of my own repairs, but...
My problem is, I'm a 17 year old kid with nothing but Google for info on how to fix stuff, and the only thing I get out of Google on valve adjusting is 'you should go get a valve adjustment'

Anyone know how to adjust the valves, or where to find out how? I assume you take the valve cover off, line the crank up so the valves are closed and turn the nut until it's tight enough, but... that's all I've got.

And sorry for bumping ancient history, btw.
