oil leak from prechamber???

My 83 300td seems to have started to weep up top. I cleaned her up and replaced the valve cover gasket as the first guess as to solving this, but after a 10 minute test drive this is what I found. How do I remedy this? I recently swapped in 3 new injectors and heat shields and questioned how clean I was able to get the heat shield to seat. Is there a better way to clean out the holes than to stuff a clean rag into them? I also torqued to spec according to my toy torque wrench but I guess it could be light. Perhaps I should snug them up a bit? Btw, even the 2 injectors that I did not swap out leak as well. I also thought that maybe the leak doesn't come from the injectors. Is there a possibility it is from the head bolts?

If your valve cover was leaking, then this could be just oil that accumulated in the treads of the pre chamber ring.
Spay it of with carb cleaner and blow it of with compressed air.

X2 on what 1960Mog said.

If you noticed when you looked down inside your Prechambers they should have had dry powdery Carbon inside of them.

If that was the case there is no way for Oil to work up to the Injectors.

If Oil was getting pumped up into the Prechamber you would have a serious miss or at least some smoke issue going on.
