Re: oil is being pulled from valve cover to air filter on...
That sounds like the reed valve sticking or dirty.
You will need to take out the reed valve, clean and re-install. Be aware that a small amount of oil is common, also do not over fill the oil. The full mark is hot. Too much oil in the crakcase can build up pressure and keep the reed valve open.
