maybe your valve covers aren't baffled

is it a ton of oil or just a little runnin out the breather? if thats the case use a highly baffled breather with a fitting for a transfer tube, run the transfer tube up to the air cleaner, hopefully its got a trasnfer tube fitting or provisions to ad one.... once hopefully it wont be enough oil to climb all the way up the baffle and the tube into your air cleaner.... if it is, you can get a kit to ad a filter to the end of the transfer tube inside your air cleaner.... that should take care of it
