The past two times I changed my oil I never noticed a oil plug gasket. I'm pretty there is suppose to be one because I see it in the manual and I've had Honda's in the past. It doesn't leak or anything, maybe its stuck on the pan. Just a thought.

 

mine was on the plug, it was hard to tell that it was there (it was black around the edges), but I pulled it off with some pliers it was stuck on there, I would also check on the pan, they get stuck there sometimes.

 

yea ill check again this weekend. never really bothered me cuz it wasn't leaking. but now that my car is burning a qt of oil per change thought id check if there were any leaks.

 

ditto...same thing happened to me.

u want to change that everytime u change the oil bc its a crush washer to prevent u from overthreading when u tighten it. so everytime u take it off and tighten it, it loses its "crushability"

 

Those are probably crush washers and should be replaced each time you put the plug back in... they are designed to crush once.
