Kohler 7000 series engine with 189 hours

[Robzilla]

Does anyone have any ideas why this is doing this. Looks like it’s spitting oil out of left side of engine. Just started doing it today, it’s coming from where I have it circled in the picture. It’s not coming from valve cover.
Mower is a Hustler Raptor Sd 54 with Kohler engine. It has 189 hours on it. I changed spark plugs and oil+filter, air filter today.

Any help would be appreciated,
Rob

To me that looks like a blown head gasket.

We've done alot of Kohler head gaskets. They have an updated head gasket P/N 32 841 02. I think they've known about this problem for awhile, but seems like they still put the weak head gaskets in from the factory??

I found the leak. It is coming out of the left side of manifold. I didn’t get a chance to take part off last night, planning on taking off today. It is leaking on left side, only at the left bolt. Will update with what I find. Hoping it’s only a gasket.
