There is only 1 drain plug. I just changed my oil few days ago.
I might need a new crush washer... where are we getting those from?
might?
you should always be changing your crush washer every time you do your oil change.. the dealer parts dept can sell you a baggie but it also comes with the OEM Honda filters I buy
I took the liberty of running the original photo through Photoshop and I think the image below shows the OP's area of concern. But since I don't I own a 1G RDX, I can only speculate what the unknown bolt is. You should only have to remove what I've indicated to be the oil drain plug. Sorry about my spelling error...Uknown = unknown!

Looks like damage from a curb check (but could also just be a stain - hard to tell for sure from the image alone). I had a gouge on the sidewall of mine that looked like that - it may be ok if it doesn't go completely through, but otherwise it may be a safety risk. My tire ended up being fine for its remaining useful life.
Also, for that leak, it's not likely coming from that bolt, but rather dripping off that bolt because it is the lowest part of the pan from where the actual leak is. Mine drips from the same spot, but I am *pretty* sure it's the pan gasket wearing out. It's not super high on the priority list, but I'll need to address it eventually.
I don’t know if you can see it but it’s where oil is leaking from
@Locsta
If you are observing oil accumulation at that 'mystery' bolt, you may have an oil leak higher up on the #15 oil filter base at the rear of the engine.
Probably the o-rings or seals #16 & #17?
The 'mystery' bolt (yellow arrow) is one of four 12X35 flange bolts that fasten the torque rod bracket (magenta arrow).
Below is a better picture of the rear of the engine that your picture does not show.
Yellow arrow is the 'mystery' bolt, magenta arrow is the torque rod bracket; therefore, if the 'mystery' bolt has oil accumulation there could be oil leaking from the oil filter base, as mentioned above, circled in green with gravity pulling it down to settle on the 'mystery' 12X35 flange bolt.
Ok that’s a lot of useful info I didn’t think to use the Acura diagram for my car, seems like the oil is leaking from the green circled area but I haven’t looked there. When my car isn’t warmed up and on a slope like a driveway it’s the only time I notice leaking.
i tried to get a new oil pan but it’s worth more than what is worth fixing until it gets worse than I will go have a estimate before fidgeting around with the oil storage.
Finally managed to fix the o ring seals on the filter gasket and seems to prevent the leaking. The old seals were squished in probably had no structure to keep the oil from dripping out, got the new seals from a Honda/acura locally and it doesn’t leak for the time being.
