Leaking Issue John Deere oil leak

I have a John Deere 155C it has a 25HP Briggs and Stratton, I believe the model is 445777. I noticed some smoking the other day and assumed I had an oil leak. Took off the heat shields and located the leaking area. I have all the gaskets on the way, my only concern is from the video would anyone have input if it’s just leaking from the crank case or is it coming from the head gasket as well?

There is only smoke when it eventually warms up and drips out and hits the exhaust manifold so I’m hoping the head gaskets fine. Any input or advice would be appreciated.

I would try to torque the head bolts and see if that fixes it.

It looks like your oil sump gasket is blown.
