ok Oil leak Returns

ok a while back i noticed oil spitting out my exhaust. I was told by a few people that it was probley my turbo, which it was. But now its spitting oil out again but only after it sits for a while. Is this something to do with the valves or seals not seating right. It only spits a little oil for about 30secs or so. But i know any oil is not good. Any info or suggestions or ideas.
