Ok, going to be as descriptive and informative as I can, but please ask questions as I'm sure there will be need for it.
Scenario
Car starts fine, no oil burning. After a few minutes, usually about ONE, it will start to puff smoke. If I drive the car, no smoke even when I get on it hard or when I'm idling down. From what others have said, it sounds like a turbo rear seal going out; pulling oil on idle, but "sealed" ok when under boost or enough pressure present. This is the only time it smokes. Running a 1 piece intake with the PCV valve running to the top vacuum hole and I don't have a PCV or catch can going back into the intake. It's venting to atmosphere. BTW, Kevin and I talked about the need to have the PCV running back to the pre-turbo intake side, so please don't post a link about the need for it.
Assessment
Kevin (DodgeZ) and I pulled the head off tonight to find NO oil anywhere in the exhaust on the turbo end and no real signs of significant oil leaking from the seals. There is SOME oil on the valves when the exhaust valves are extended, but VERY LITTLE when they are closed, almost unnoticeable. Please take a look at the pics to see if the oil we saw on the exhaust valves is normal or would cause the smoke problem mentioned above.
There are some really odd things happening, but one that seems to be a potential problem and that is a leaky valve cover. There were good traces of oil around the manifold gasket close to cylinders 3 and 4 and a TAD close to 1. The valve cover was loose close to cylinder 1 and fairly tight close to cylinders 3 and 4. The nut for the lower exhaust stud on number 4 was gone, the rest were tight. All of the bolts for the intake where tight.
Here's where it gets fun. Runners 1 and 4 were the ones that have oil on them (see pics), however NEITHER of the two runners on the head for 1 and 4 had ANY OIL on them, they were totally dry.
Runners 2 and 3 had ZERO oil on the intake, yet both 2 and 3 had a little oil reside in the intake runners on the head.
Both of us are pretty stumped on where the oil could be coming from, however based on the amount of oil in runners 1 and 4, this seems to be the culprit for the oil, although the plugs really aren't fouled, yet they are a little dirty. Maybe this is it?
Now because I have the valve cover vent going to the upper vacuum hole on the 1 piece intake, could this be drawing in oil and then spreading/sending it to runners 1 and 4? Anyone who is versed in head work or has had experience with heads burning oil and oil on the exhaust valves, please lend your expertise and help. If the head needs to be re-worked, I can take it locally to a place to have them work on it. I just need to know what to do next.

Cylinder1, Cylinder2, Cylinder3, Cylinder4
Note that cylinder 1 has the most oil in the runner and you can see where it is burning in the chamber, but there is NO OIL in the runner on the head!!!! AGHH!!!!
