Oil Leak

Hello All. I have an 02 or 04 grizzly 660 that has an oil leak. I am by no means a mechanic, but I believe I have found the source of the leak. The oil was leaking around and below the exhaust ports on the cylinder head. I removed both exhausts from the studs and the gaskets. The exhaust had some carbon buildup in it, but it was very dry and no oil. After further looking, it appears that there is oil between both exhaust ports in a cavity. I cannot get my finger all the way back in, but there was oil in that cavity. I was able to get a picture and it appears that there is some type of bolt back in there. My questions is, what do you think is causing the problem and what it that bolt back in there? I have attached a photo. Thanks for any help!

If you zoom in and look at the right side of the cavity, does that look like a vertical crack?

Something does look weird in there. Hard to tell exactly what it is from a picture though
