Smell it, see if it smells like gas, but it does look like leaky valve cover. If its you injector just get the seal kit from the dealer or parts store and replace all the O-rings. Chill

You can tell because the intake runners directly under those injectors are way too clean in comparison to everything else. I have the same problem on #4 only.
Each injector has I believe 2 rubber 0-rings, and 2 plastic cushions. From what I understand, usually the rubber is worn and that is where it leaks from. I just bought all the o-rings and all the cushions from Majestic for a total of $41 including shipping.
I didn't pull them out yet though, cause I plan to torque the rail to spec when I put everything back, and my torque wrench is MIA.
Peep my thread where I got all the assistance about this...
I suggest getting rid of the old mess to see if you have a current leak. Clean the area around the injectors, and the area on the head just below the valve cover gasket, then check it after you've driven around. Gas will smell like gas and be clear, used oil is dark, it'll be easy to tell what the deal is before you buy parts or start disassembling.
From the top down the injectors have:
a filter
a small o-ring that sits on top of the injector and seals in the fuel rail
a cushion for the fuel rail that goes around the injector body
a large o-ring that seals in the manifold
and a hard plastic spacer ring that goes between the o-ring and the manifold, and does not usually wear out or need to be replaced.
If you do end up having to replace the injector seals, apply a light oil to all rubber parts upon install, and put the injectors into the rail before you put them into the manifold.

PM me and get it done right!
If they were leaking, you'd be able to smell the gas inside the car when your climate controls are on outside air. That's how I discovered two of mine were leaking. Just contact your local honda parts desk for the o-ring kit.....it's relatively cheap.
before u condemn the injector orings make sure the injector body isnt leaking...ive been burned before like that....replaced the orings and it still had a leak...

& a word of advice, once you pull off the seals off the injectors. chances are you wont be able to put them back
