It could be that the PCV valve is clogged, causing too much crankcase pressure so it gets sucked through the other side. Try changing the PCV and see if the problem goes away.

You should be able to clean the oil out of the TB out with some good old spray carb cleaner. Head over to Dynamic up on Washington Ave. :)

PCV blowby. change the valve, clean everything up (sensors and ducting, spray some brake parts cleaner through it and dry it out nice) and run from there. the oil in the manifold will eventually get outta there. good idea to spray some carb cleaner through the plenum to clean it up. and wish for the best!
