oil in bottom of airbox

[rollinghelmet]

why would i have lots of oil in the bottom of my airbox only been for a few rides since carb and airbox cleanout
should i just put a breather on engine oil breather hose and block off airbox hole

[andyb]

Lotsa blowby in the motor?  Tired rings and such = more crankcase pressure = more oily air coming out the breather, yes? 

Is it using significant amounts of oil?  Is the engine a high mileage unit?

Stock air filter, or an oiled element of some sort?  I've seen plenty of oil in the bottom of airboxes with K&N or foam filters in them....

everything is stock, maybe i will try better quality oil and not let it get to hot on idle, any Australian oil recommendations
