Dipstick o-ring help?

I know there are a lot of threads mentioning this, but I couldn't find anything too specific on how the o-ring "seats". I replaced my ccv a few weeks ago as preventative and now I get the honk. Either the new ccv is defective or I have a leak, so after searching some I decided to replace the o-ring which I didn't pay much attention to when I did the job the first time around.

So I just pulled the dipstick and maybe it fell off just now or when I did the ccv a few weeks ago, but I don't see any old o-ring (surprisingly no oil leaking there). I also can't feel any place where the o-ring would sit. Some people mentioned putting it on the guide tube then pushing it in with a screwdriver, but it doesn't feel like there is anything that will stop it from falling all the way into the oil pan. Is there some kind of groove or lip in there that I am missing? I couldn't feel anything and don't want possibly two o-rings in my oil pan now =/

Update:

After replacing the dipstick o-ring the honk is gone and mustard under oil cap is also gone.

I don't recall exactly, but if there's an o-ring you should see it on guidetube, or stuck inside the hole the guidetube goes into.

Mine fit in fine...though I know I'd also read threads of guys with issues...some who banged it in with a hammer...not necessary I don't think...not if it's aligned right.

Possibly the o-ring came off when you did ccv? Anyway, if you have no o-ring, that might explain the honk, but I'm not sure. It should be a sealed system...so if no o-ring...no seal.

Maybe it broke apart and fell into the oil pan, but there's a filter before the pump...and honestly, even if it got to the pump, I suspect it wouldn't hurt anything.

You need an 0-ring though.

Thanks for the input. I think I got in in there now, but we'll see if the honk returns. Still putting it back together. On a side note, I probably shouldn't attempt repairs outside in record setting blizzards but I had to make the most of my day off

I just pushed as hard as I could using all my weight and wiggled the hell out of it for a while. The tube is definitely lined up, just the o-ring wouldn't press into the hole past where the bump stop on the guide tube sits. The hole for the bolt eventually lined up, so it's ether in or I bent the tube. Pretty sure it's in though because I tugged up a little and there was resistance whereas before there was none. If the old one did fall in, tiny bit of rubber should just break apart eventually I guess
