318 oil leak

I didn't look last night (because I didn't know about it). I took a pic but cannot see if it does. I'm stuck at this place called work and will check it out tonight. From my pic there are only 3 bolts and the top left does not look like it does. I read that is a weep hole for oil, some have some do not. Opinion on if I should or not. I can easily chuck it up in lathe and drill one if needed.

I sent this before I saw TrailBeast's post. Thank you for the info
