OK, so first thing I read was you were going to change the oil. Then you cleaned the radiator "inside and out" and noticed it blowing oil out of the "blow by port". I'm wondering if you overfilled the crankcase.
No. I checked it's level. I considered I left the plug loose. Refilled it again tested the level. Ran it a bit and noticed excessive smoke this time coming from underneath. It was coming from a hose that while running was spewing oil. The hose was connected to the top of the valve cover. I also at time I seen a trail of oil where I had already mowed. The tractor had been running hot until I flushed the radiator inside and out. It's likely a blown head gasket or cracked a ring is what a Kioti tech told me.
