Default Oil in breather box on 350 Rancher

Went to inspect the air filter today and I notice motor oil pooled up on the bottom of the box. It covers about half of the bottom. Is this backing up through the crankcase vent hose? Surely it's not coming out through the carburetor. If it is backing up through the vent hose is there anything other than over full that would be causing it?

It'll start smoking before long my 03 350 done the same thing. Sold it after it was dumping close to half a quart in the box after a long ride. Not sure what caused it since mine wasnt over full. Welcome to the forum

did you oil youre air filter the last time with just engin oil ....(if yes then it may just be the extra oil that dripped out the filter )
also a broken ring will pump oil up the breather into the air box from blow by ....

My son cleaned it the last time at a friends house with filter oil. Would it be smoking any if a ring were broke?
And to answer JWJR's question Yes, my son rolled it once a couple of weeks ago.

Oil most likely came in when he rolled it. Clean it out and keep an eye on it.
