ATC 185s oil bubbling

[delaswim]

Hello everyone. I'm sorting out my 185s, and am noticing that it oil bubbles out of the top of the head through what looks to be a missing bolt hole. I'm not sure if there's a head bolt that was never replaced or what. It's been like this since I got it.

Can someone tell me if it's just a missing bolt, or a vent hole, or what?

Thanks!

Here's a picture of oil bubbling out of the hole. Hopefully this link works:

I just keep getting errors for the first link and the pic doesn't show up for me on the second post

I’m not able to open or view your photo, but your story sure does remind me of a poor mountaineer named Jed who could barely keep his family fed.

Look at the side of the head in this pic. See the tiny hole on the side of the head in the finned area just below the CDI trigger/camshaft area..... That bolt #15 in the pic is supposed to go in that hole and all the way thru the head (see the corresponding hole in the head gasket in the pic below the head)

Is that where it's coming out?

We'll see if this works. I'm trying to use Photobucket, but the website says I'm over my limit. I've only uploaded 3 pictures, all of which are shared on this https://photos.app.goo.gl/tnFqTjbdCoadHM447

Maybe this one will be clearer:

So it would makes sense for the engine to leak oil through this bolt hole. Simply putting a new bolt in will fix the problem right?

Is the circled bolt hole on this diagram the one I'm picturing? I can't tell. If it is, this is just a missing 6mm Allen head bolt?
