2008 Hisun Supermach 700 oil dripping from air box drain

[Lucas Lenartowicz]

I have oil dripping off the the tube that drains the air box. I have checked the inside of the air box on a few occasions and there is never any fresh oil. So I don't know if the oil is there from any previous leaks/spills or if there is sometime i am missing. Also it is missing the oil/air separator but I checked the end of the crankcase breather tube and it is dry, even when running.

Any help appreciated

check your oil level, be sure it isn't over the fill mark, or smells like gasoline.

No it constantly burns oil so it maybe overfilled momentarily. it just is that i did't see a direct hole inside the airbox to the drain tube and I wondered whether there was something  weird with an extra compartment in the floor of the air box. But now that I think about it, it doesn't make sense. Sometimes a person needs to think out loud. I'll keeping an eye on it.

Thanks

P.S. if the oil level is maintained correctly is the oil/air separator necessary?

Usually the crankcase ventilation tube comes up into the airbox. Sounds like blow by coming up through the crankcase ventilation. If it it's old and worn, some amount of blow by is pretty much normal. 

But oil being overfilled will cause it also. So if that's not the case. And it's not caused by being old, and just normal wear. Or if it's excessive. Then you'll need to check a few things. Starting with compression. To find the source of the blow by. Piston rings are the usual culprit.
