I think 10% ona fresh engine is too high. Leakdowns tell you the condition of the compression ring.. the top ring.. But if the top ring isnt sealing gasses, the 2nd ring isn't scraping the oil well and the oil rings arent doing their job well either. Ona modern built moly ringed engine the cross hatch should barely be visible. The rings need a smooth finish to seat properly and they will show less than 4% leakdown if they have. IMO, yours haven't. If you disconnected the PCV and drove it for 50 miles you should see no drop in oil level if it's sucking past the valve. I dont think it is.

Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.
