Default 6.5 NH hunts and throws oil

I have a 6.5 KW NH in a 1985 motorhome that started hunting and throwing oil out with the cooling air. Its a 3CRV16004P ser# B853882654. I think the hunting has to do with the choke. But the main question is, where is the oil comming from. I pulled the unit out of the MH and into the garage, pulled all the sheet metal, pulled the flywheel off and do not see any recent looking oil leaks. There was what looked like fresh oil under the oil pan, but it did not appear that there was a way for it to get into the air flow. Any sugestions and does anyone have a parts breakdown for the crank seal and the gasket for the assembly that covers the govener? Sorry for the long post, but this one has me.

The hunting is from lean fuel most of the time. For the oil leak clean the crankcase breather.

Thanks. I checked the breather it looked clean, but I ran some carb cleaner through it anyway. It was fairly clean, oil but no dirt like I expected.
