Recently I've noticed that I have a small amount of oil coming from the pressure box after shutdown. This amounts to about a tablespoon or two of oil collecting below the engine. I'm not getting any oil blowing out from below the engine when flying but the oil collecting on the hanger floor is frustrating. I've traced it down to the drain hose connected to the two ports on the pressure box. When the engine is cool I can touch the bottom of the hose and get a drop or two of oil on my finger. I'm thinking that it could be oil condensation. My plugs and exhaust appear clean, not sootey. Any ideas?
