How much oil should coming from the oil breather? What causes the breather to blow oil back into the airbox? I pulled my cover on my airbox and I have small pooling of oil and smell of gas in the bottom where the cover attaches (I have a stock airbox) and it appears that it is starting to work on the rubber o-ring I am seeing cracking in the rubber o-ring. I am wondering oil blow leaking back into the airbox is related to why I am still going through so much oil? almost 2 qts. in 100 miles?
